-If this extension is supported, an OpenCL image object can be created from a

+<p>This section describes the <strong>cl_khr_dx9_media_sharing</strong> extension.
+The goal of this extension is to allow applications to use media surfaces as
+OpenCL memory objects.
+This allows efficient sharing of data between OpenCL and selected adapter
+APIs (only DX9 for now).
+If this extension is supported, an OpenCL image object can be created from a
+media surface and the OpenCL API can be used to execute kernels that read
+and/or write memory objects that are media surfaces.
+Note that OpenCL memory objects may be created from the adapter media
+surface if and only if the OpenCL context has been created from that
+adapter.</p>

-For each file in this path, the ICD Loader opens the file as a text file.
-The expected format for the file is a single line of text which specifies
-the Vendor ICD&#8217;s library.
-The ICD Loader will attempt to open that file as a shared object using
-dlopen().
-Note that the library specified may be an absolute path or just a file name.</p>

-<p>RESOLVED: Such functions will be a noop for all calls through the ICD.</p>
+<p>RESOLVED: No, as this may be very difficult since the synchronization would

-The components of vector type can be accessed using swizzle expression.
-The syntax of a swizzle expression is similar to syntax used in class member access expression <em>[ISO/IEC 14882:2014: expr.ref, ch. 5.2.5]</em>:
-The swizzle expression is a postfix expression formed with a postfix expression followed by a dot <span class="monospaced">.</span> or an arrow <span class="monospaced">-&gt;</span> and then followed by an <em>vector-swizzle-selector</em>. The postfix expression before the dot or arrow is evaluated. The result of that evaluation, together with the <em>vector-swizzle-selector</em>, determines the result of the entire postfix expression.

-<em>vector-swizzle-selector</em>, in a form of <em>vector-swizzle-xyzw-selector</em>, <em>vector-swizzle-rgba-selector</em> or <em>vector-swizzle-num-selector</em> can specify multiple values.
-Each value selects single component.
-Values in a selector can be repeated and specified in any order.
-A number of values in a selector including repeated values is called the swizzle size.

-<h5 id="vector-types-and-usual-arithmetic-conversions">Vector Types and Usual Arithmetic Conversions</h5>
-<div class="paragraph"><p>Many operators that expect operands of arithmetic type cause conversions and yield result types in a similar way.
-The purpose is to determine a common real type for the operands and result.
-For the specified operands, each operand is converted, without change of type domain, to a type whose corresponding real type is the common real type.
-For this purpose, all vector types shall be considered to have higher conversion ranks than scalars.
-Unless explicitly stated otherwise, the common real type is also the corresponding real type of the result, whose type domain is the type domain of the operands if they are the same, and complex otherwise.
-This pattern is called the usual arithmetic conversions.
-If the operands are of more than one vector type, then an error shall occur.
-Implicit conversions between vector types are not permitted, per <em><a href="#implicit-type-conversions">Implicit Type Conversions</a> section</em>.</p></div>
-<div class="paragraph"><p>Otherwise, if there is only a single vector type, and all other operands are scalar types, the scalar types are converted to the type of the vector element, then widened into a new vector containing the same number of elements as the vector, by duplication of the scalar value across the width of the new vector.</p></div>

-<div class="paragraph"><p>For 3-component vector data types, the size of the data type is <span class="monospaced">4 * sizeof(component)</span>.
-This means that a 3-component vector data type will be aligned to a <span class="monospaced">4 * sizeof(component)</span> boundary.
-The <span class="monospaced">vload3</span> and <span class="monospaced">vstore3</span> built-in functions can be used to read and write, respectively, 3-component vector data types from an array of packed scalar data type.</p></div>
-<div class="paragraph"><p>A built-in data type that is not a power of two bytes in size must be aligned to the next larger power of two.
-This rule applies to built-in types only, not structs or unions.</p></div>
-<div class="paragraph"><p>The OpenCL C++ compiler is responsible for aligning data items to the appropriate alignment as required by the data type.
-For arguments to a kernel function declared to be a pointer to a data type, the OpenCL compiler can assume that the pointee is always appropriately aligned as required by the data type.
-The behavior of an unaligned load or store is undefined, except for the <span class="monospaced">vload</span><em>n</em>, <span class="monospaced">vload_half</span><em>n</em>, <span class="monospaced">vstore</span><em>n</em>, and <span class="monospaced">vstore_half</span><em>n</em> functions defined in <em><a href="#vector-data-load-and-store-functions">Vector Data Load and Store Functions</a> section</em>.

-<div class="paragraph"><p>Note that the alignment of any given struct or union type is required by the C++ standard to be at least a perfect multiple of the lowest common multiple of the alignments of all of the members of the struct or union in question and must also be a power of two.

-In the example above, the size of each short is 2 bytes, and therefore the size of the entire struct S type is 6 bytes.
-The smallest power of two which is greater than or equal to that is 8, so the compiler sets the alignment for the entire struct S type to 8 bytes.</p></div>
-<div class="paragraph"><p>Note that the effectiveness of aligned attributes may be limited by inherent limitations of the OpenCL device and compiler.
-For some devices, the OpenCL compiler may only be able to arrange for variables to be aligned up to a certain maximum alignment.
-If the OpenCL compiler is only able to align variables up to a maximum of 8 byte alignment, then specifying <span class="monospaced">aligned(16)</span> will still only provide you with 8 byte alignment.

-A conforming implementation is not required to autovectorize code, but shall support the hint.
-A compiler may autovectorize, even if no hint is provided.

-<div class="ulist"><ul>
-<li>
-<p>
-The <em>l</em> modifier followed by a <em>c</em> conversion specifier or <em>s</em> conversion specifier is not supported by OpenCL C++.
-</p>
-</li>
-<li>
-<p>
-The <em>ll</em>, <em>j</em>, <em>z</em>, <em>t</em>, and <em>L</em> length modifiers are not supported by OpenCL C++ but are reserved.
-</p>
-</li>
-<li>
-<p>
-The <em>n</em> conversion specifier is not supported by OpenCL C++ but is reserved.
-</p>
-</li>
-<li>
-<p>
-OpenCL C++ adds the optional <em>vn</em> vector specifier to support printing of vector types.
-</p>
-</li>
-<li>
-<p>
-The conversion specifiers <em>f</em>, <em>F</em>, <em>e</em>, <em>E</em>, <em>g</em>, <em>G</em>, <em>a</em>, <em>A</em> convert a float argument to a double only if the double data type is supported.
-Refer to the description of <span class="monospaced">CL_DEVICE_DOUBLE_FP_CONFIG</span> in <em>table 4.3</em>.
-If the double data type is not supported, the argument will be a float instead of a double.
-</p>
-</li>
-<li>
-<p>
-For the embedded profile, the <em>l</em> length modifier is supported only if 64-bit integers are supported.
-</p>
-</li>
-<li>
-<p>
-In OpenCL C++, <span class="monospaced">printf</span> returns 0 if it was executed successfully and -1 otherwise vs. C++14 where <span class="monospaced">printf</span> returns the number of characters printed or a negative value if an output or encoding error occurred.
-</p>
-</li>
-<li>
-<p>
-In OpenCL C++, the conversion specifier <em>s</em> can only be used for arguments that are literal strings.

-<div class="paragraph"><p>The OpenCL C++ programming language implements a subset of the C++14 atomics (refer to <em>chapter 29</em> of the C++14 specification) and synchronization operations.
-These operations play a special role in making assignments in one work-item visible to another.
-Please note that this chapter only presents synopsis of the atomics library and differences from C++14 specification.</p></div>

-<td class="content">With fine-grained system SVM, sharing happens at the granularity of individual loads and stores anywhere in host memory.
-Memory consistency is always guaranteed at synchronization points, but to obtain finer control over consistency, the OpenCL atomics functions may be used to ensure that the updates to individual data values made by
-one unit of execution are visible to other execution units.
-In particular, when a host thread needs fine control over the consistency of memory that is shared with one or more OpenCL devices, it must use atomic and fence operations that are compatible with the C++14 atomic operations <a href="#ftn9">[9</a>].</td>

-<div class="sectionbody">
-<div class="paragraph"><p>This section describes features of the C++14 and IEEE 754 standards that must be supported by all OpenCL compliant devices.</p></div>
-<div class="paragraph"><p>This section describes the functionality that must be supported by all OpenCL devices for single precision floating-point numbers.
-Currently, only single precision and half precision floating-point is a requirement.
-Double precision floating-point is an optional feature.</p></div>
-<div class="sect2">
-<h3 id="rounding-modes-1">4.1. Rounding Modes</h3>
-<div class="paragraph"><p>Floating-point calculations may be carried out internally with extra precision and then rounded to fit into the destination type.
-IEEE 754 defines four possible rounding modes:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Round to nearest even.
-</p>
-</li>
-<li>
-<p>
-Round toward +infinity.

-<p>
-Round toward -infinity.

-</li>
-<li>
-<p>
-Round toward zero.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p><em>Round to nearest even</em> is currently the only rounding mode required <a href="#ftn30">[30</a>] by the OpenCL specification for single precision and double precision operations and is therefore the default rounding mode.
-In addition, only static selection of rounding mode is supported.
-Static and dynamic selection of rounding mode is not supported.</p></div>

-<h3 id="inf-nan-and-denormalized-numbers">4.2. INF, NaN and Denormalized Numbers</h3>
-<div class="paragraph"><p>INF and NaNs must be supported.
-Support for signaling NaNs is not required.</p></div>
-<div class="paragraph"><p>Support for denormalized numbers with single precision floating-point is optional.
-Denormalized single precision floating-point numbers passed as input or produced as the output of single precision floating-point operations such as add, sub, mul, divide, and the functions defined in <a href="#math-functions">Math Functions</a>, <a href="#common-functions">Common Functions</a> and <a href="#geometric-functions">Geometric Functions</a> may be flushed to zero.</p></div>

-<div class="sect2">
-<h3 id="floating-point-exceptions">4.3. Floating-Point Exceptions</h3>
-<div class="paragraph"><p>Floating-point exceptions are disabled in OpenCL.
-The result of a floating-point exception must match the IEEE 754 spec for the exceptions not enabled case.
-Whether and when the implementation sets floating-point flags or raises floating-point exceptions is implementation-defined.
-This standard provides no method for querying, clearing or setting floating-point flags or trapping raised exceptions.
-Due to non-performance, non-portability of trap mechanisms and the impracticality of servicing precise exceptions in a vector context (especially on heterogeneous hardware), such features are discouraged.</p></div>
-<div class="paragraph"><p>Implementations that nevertheless support such operations through an extension to the standard shall initialize with all exception flags cleared and the exception masks set so that exceptions raised by arithmetic operations do not trigger a trap to be taken.
-If the underlying work is reused by the implementation, the implementation is however not responsible for reclearing the flags or resetting exception masks to default values before entering the kernel.
-That is to say that kernels that do not inspect flags or enable traps are licensed to expect that their arithmetic will not trigger a trap.
-Those kernels that do examine flags or enable traps are responsible for clearing flag state and disabling all traps before returning control to the implementation.
-Whether or when the underlying work-item (and accompanying global floating-point state if any) is reused is implementation-defined.</p></div>
-<div class="paragraph"><p>The expressions math_errorhandling and MATH_ERREXCEPT are reserved for use by this standard, but not defined.
-Implementations that extend this specification with support for floating-point exceptions shall define math_errorhandling and MATH_ERREXCEPT per ISO / IEC 9899 : TC2.</p></div>

-<h3 id="relative-error-as-ulps">4.4. Relative Error as ULPs</h3>
-<div class="paragraph"><p>In this section we discuss the maximum relative error defined as ulp (units in the last place).
-Addition, subtraction, multiplication, fused multiply-add and conversion between integer and a single precision floating-point format are IEEE 754 compliant and are therefore correctly rounded.
-Conversion between floating-point formats and explicit conversions specified in <em><a href="#conversions-library">Conversions Library</a> section</em> must be correctly rounded.</p></div>
-<div class="paragraph"><p>The ULP is defined as follows:</p></div>
-<div class="paragraph"><p>If x is a real number that lies between two ﬁnite consecutive floating-point numbers a and b, without being equal to one of them, then ulp(x) = |b −a|, otherwise ulp(x) is the distance between the two non-equal ﬁnite floating-point numbers nearest x.
-Moreover, ulp(NaN) is NaN.</p></div>

-The <span class="monospaced">as_type&lt;T&gt;</span> construct is intended to compile to no instructions on devices that use a shared register file designed to operate on both the operand and result types.
-Note that while differences in memory organization are expected to largely be limited to those arising from endianness, the register based representation may also differ due to size of the element in register.
-(For example, an architecture may load a char into a 32-bit register, or a char vector into a SIMD vector register with fixed 32-bit element size.)
-If the element count does not match, then the implementation should pick a data representation that most closely matches what would happen if an appropriate result type operator was applied to a register containing data of the source type.
-So, for example if an implementation stores all single precision data as double in register, it should implement <span class="monospaced">as_type&lt;int&gt;(float)</span> by first downconverting  the double to single precision and then (if necessary) moving the single precision bits to a register suitable for operating on integer data.

-<div class="paragraph"><p><strong>OpenCL</strong> (Open Computing Language) is an open royalty-free standard for general purpose parallel programming across CPUs, GPUs and other processors, giving software developers portable and efficient access to the power of these heterogeneous processing platforms.</p></div>
-<div class="paragraph"><p>Parallel programs in OpenCL may be written in the OpenCL C source language, or may compiled from OpenCL C, OpenCL C++, or other source languages into SPIR-V modules.</p></div>
-<div class="paragraph"><p>All SPIR-V intermediate binary modules are consumed by environments, such as an API, a specific version of an API, or an implementation of an API.  The environment describes required support for some SPIR-V capabilities, additional semantics for some SPIR-V instructions, and additional validation rules a module must adhere to in order to be considered valid.</p></div>
-<div class="paragraph"><p>This document describes the environment for implementations of the OpenCL API.  It is written for compiler developers who are generating SPIR-V modules to be consumed by the OpenCL API, for implementors of the OpenCL API who are consuming SPIR-V modules, and by software developers who are using SPIR-V modules with the OpenCL API.</p></div>

-<h2 id="consumption">SPIR-V Consumption</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>This section describes common properties of all OpenCL environments.  Subsequent sections describe environments for specific versions of OpenCL, and how an environment may additionally be modified via OpenCL or SPIR-V extensions.</p></div>
-<div class="paragraph"><p>A SPIR-V module passed to an OpenCL environment is interpreted as a series of 32-bit words in host endianness, with literal strings packed as described in the SPIR-V specification.  The first few words of the SPIR-V module must be a magic number and a SPIR-V version number, as described in the SPIR-V specification.</p></div>
-<div class="sect2">
-<h3 id="_validation_rules">Validation Rules</h3>
-<div class="paragraph"><p>The following are a list of validation rules that apply to SPIR-V modules executing in all OpenCL environments:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-The <em>Execution Model</em> declared in <strong>OpEntryPoint</strong> must be <strong>Kernel</strong>.
-</p>
-</li>
-<li>
-<p>
-The <em>Addressing Model</em> declared in <strong>OpMemoryModel</strong> must be either <strong>Physical32</strong> or <strong>Physical64</strong>:
-</p>
-<div class="ulist"><ul>
-<li>
-<p>
-Modules indicating a <strong>Physical32</strong> <em>Addressing Model</em> are valid for OpenCL devices reporting <span class="monospaced">32</span> for <span class="monospaced">CL_DEVICE_ADDRESS_BITS</span>.
-</p>
-</li>
-<li>
-<p>
-Modules indicating a <strong>Physical64</strong> <em>Addressing Model</em> are valid for OpenCL devices reporting <span class="monospaced">64</span> for <span class="monospaced">CL_DEVICE_ADDRESS_BITS</span>.
-</p>
-</li>
-</ul></div>
-</li>
-<li>
-<p>
-The <em>Memory Model</em> declared in <strong>OpMemoryModel</strong> must be <strong>OpenCL</strong>.
-</p>
-</li>
-<li>
-<p>
-For all <strong>OpTypeImage</strong> type-declaration instructions:
-</p>
-<div class="ulist"><ul>
-<li>
-<p>
-<em>MS</em> must be 0, indicating single-sampled content.
-</p>
-</li>
-<li>
-<p>
-<em>Arrayed</em> may only be set to 1, indicating arrayed content, when <em>Dim</em> is set to <strong>1D</strong> or <strong>2D</strong>.
-</p>
-</li>
-</ul></div>
-</li>
-<li>
-<p>
-The image write instruction <strong>OpImageWrite</strong> must not include any optional <em>Image Operands</em>.
-</p>
-</li>
-<li>
-<p>
-The image read instructions <strong>OpImageRead</strong>, <strong>OpImageFetch</strong>, and <strong>OpImageSampleExplicitLod</strong> must not include the optional <em>Image Operand</em> <strong>ConstOffset</strong>.
-</p>
-</li>
-<li>
-<p>
-Only 32-bit integer types are supported for the <em>Result Type</em> and/or type of <em>Value</em> for all <strong>Atomic Instructions</strong>.
-</p>
-</li>
-<li>
-<p>
-Recursion is not supported.  The static function call graph for an entry point must not contain cycles.

-<h3 id="_source_language_encoding">Source Language Encoding</h3>
-<div class="paragraph"><p>If a SPIR-V module represents a program written in OpenCL C, then the <em>Source Language</em> operand for the <strong>OpSource</strong> instruction should be <strong>OpenCL_C</strong>, and the 32-bit literal language <em>Version</em> should describe the version of OpenCL C, encoded MSB to LSB as:</p></div>
-<div class="literalblock">
-<div class="content monospaced">
-<pre>0 | Major Number | Minor Number | Revision Number (optional)</pre>
-</div></div>
-<div class="paragraph"><p>Hence, OpenCL C 1.2 would be encoded as <span class="monospaced">0x00010200</span>, and OpenCL C 2.0 as <span class="monospaced">0x00020000</span>.</p></div>
-<div class="paragraph"><p>If a SPIR-V module represents a program written in OpenCL C++, then the <em>Source Language</em> operand for the <strong>OpSource</strong> instruction should be <strong>OpenCL_CPP</strong>, and the 32-bit literal language <em>Version</em> should describe the version of OpenCL C++, encoded similarly.  Hence, OpenCL C++ 2.2 would be encoded as <span class="monospaced">0x00020200</span>.</p></div>
-<div class="paragraph"><p>The source language version is purely informational and has no semantic meaning.</p></div>

Whether and when the implementation sets floating-point flags or raises floating-point exceptions is implementation-defined.</p></div>
-<div class="paragraph"><p>This standard provides no method for querying, clearing or setting floating-point flags or trapping raised exceptions.  Due to non-performance, non-portability of trap mechanisms, and the impracticality of servicing precise exceptions in a vector context (especially on heterogeneous hardware), such features are discouraged.</p></div>
-<div class="paragraph"><p>Implementations that nevertheless support such operations through an extension to the standard shall initialize with all exception flags cleared and the exception masks set so that exceptions raised by arithmetic operations do not trigger a trap to be taken.  If the underlying work is reused by the implementation, the implementation is however not responsible for re-clearing the flags or resetting exception masks to default values before entering the kernel.  That is to say that kernels that do not inspect flags or enable traps are licensed to expect that their arithmetic will not trigger a trap.  Those kernels that do examine flags or enable traps are responsible for clearing flag state and disabling all traps before returning control to the implementation.  Whether or when the underlying work-item (and accompanying global floating-point state if any) is reused is implementation-defined.</p></div>

Conversion between floating-point formats and explicit conversions must be correctly rounded.</p></div>

-<h2 id="optional-extensions">Optional Extensions</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>This document describes the list of optional features supported by OpenCL 2.2. Optional extensions may be supported by some OpenCL devices. Optional extensions are not required to be supported by a conformant OpenCL implementation, but are expected to be widely available; they define functionality that is likely to move into the required feature set in a future revision of the OpenCL specification. A brief description of how OpenCL extensions are defined is provided below.</p></div>
-<div class="paragraph"><p>For OpenCL extensions approved by the OpenCL working group, the following naming conventions are used:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-A unique <em>name string</em> of the form "<strong>cl_khr_&lt;<em>name</em>&gt;</strong>" is associated with each extension. If the extension is supported by an implementation, this string will be present in the implementation&#8217;s CL_PLATFORM_EXTENSIONS string or CL_DEVICE_EXTENSIONS string.
-</p>
-</li>
-<li>
-<p>
-All API functions defined by the extension will have names of the form <strong>cl&lt;<em>function_name</em>&gt;KHR</strong>.
-</p>
-</li>
-<li>
-<p>
-All enumerants defined by the extension will have names of the form <strong>CL_&lt;<em>enum_name</em>&gt;_KHR.</strong>
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>OpenCL extensions approved by the OpenCL working group can be <em>promoted</em> to required core features in later revisions of OpenCL. When this occurs, the extension specifications are merged into the core specification. Functions and enumerants that are part of such promoted extensions will have the <strong>KHR</strong> affix removed. OpenCL implementations of such later revisions must also export the name strings of promoted extensions in the CL_PLATFORM_EXTENSIONS or CL_DEVICE_EXTENSIONS string, and support the <strong>KHR</strong>-affixed versions of functions and enumerants as a transition aid.</p></div>
-<div class="paragraph"><p>For vendor extensions, the following naming conventions are used:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-A unique <em>name string</em> of the form "<strong>cl_&lt;<em>vendor_name</em>&gt;_&lt;<em>name&gt;</em></strong>" is associated with each extension. If the extension is supported by an implementation, this string will be present in the implementation&#8217;s CL_PLATFORM_EXTENSIONS string or CL_DEVICE_EXTENSIONS string.
-</p>
-</li>
-<li>
-<p>
-All API functions defined by the vendor extension will have names of the form <strong>cl&lt;<em>function_name</em>&gt;&lt;<em>vendor_name</em>&gt;</strong>.
-</p>
-</li>
-<li>
-<p>
-All enumerants defined by the vendor extension will have names of the form <strong>CL_&lt;<em>enum_name</em>&gt;_&lt;<em>vendor_name</em>&gt;.</strong>

-<p>
-When the CGL binding API is supported, the attribute CL_CGL_SHAREGROUP_KHR should be set to a CGLShareGroup handle to a CGL share group object.
-</p>
-</li>
-<li>
-<p>
-When the EGL binding API is supported, the attribute CL_GL_CONTEXT_KHR should be set to an EGLContext handle to an OpenGL ES or OpenGL context, and the attribute CL_EGL_DISPLAY_KHR should be set to the EGLDisplay handle of the display used to create the OpenGL ES or OpenGL context.
-</p>
-</li>
-<li>
-<p>
-When the GLX binding API is supported, the attribute CL_GL_CONTEXT_KHR should be set to a GLXContext handle to an OpenGL context, and the attribute CL_GLX_DISPLAY_KHR should be set to the Display handle of the X Window System display used to create the OpenGL context.
-</p>
-</li>

-When the WGL binding API is supported, the attribute CL_GL_CONTEXT_KHR should be set to an HGLRC handle to an OpenGL context, and the attribute CL_WGL_HDC_KHR should be set to the HDC handle of the display used to create the OpenGL context.

-<p>
-How should the OpenGL context be identified when creating an associated OpenCL context?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>RESOLVED: by using a (display,context handle) attribute pair to identify
-an arbitrary OpenGL or OpenGL ES context with respect to one of the
-window-system binding layers EGL, GLX, or WGL, or a share group handle
-to identify a CGL share group. If a context is specified, it need not be
-current to the thread calling clCreateContext*.</p></div>
-<div class="paragraph"><p>A previously suggested approach would use a single boolean attribute
-CL_USE_GL_CONTEXT_KHR to allow creating a context associated with the
-currently bound OpenGL context. This may still be implemented as a
-separate extension, and might allow more efficient acquire/release
-behavior in the special case where they are being executed in the same
-thread as the bound GL context used to create the CL context.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-What should the format of an attribute list be?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>After considerable discussion, we think we can live with a list of
-&lt;attribute name,value&gt; pairs terminated by zero. The list is passed as
-<em>cl_context_properties *<em>properties'</em>, where cl_context_properties is
-typedefed to be 'intptr_t</em> in cl.h.</p></div>
-<div class="paragraph"><p>This effectively allows encoding all scalar integer, pointer, and handle
-values in the host API into the argument list and is analogous to the
-structure and type of EGL attribute lists. NULL attribute lists are also
-allowed. Again as for EGL, any attributes not explicitly passed in the
-list will take on a defined default value that does something
-reasonable.</p></div>
-<div class="paragraph"><p>Experience with EGL, GLX, and WGL has shown attribute lists to be a
-sufficiently flexible and general mechanism to serve the needs of
-management calls such as context creation. It is not completely general
-(encoding floating-point and non-scalar attribute values is not
-straightforward), and other approaches were suggested such as opaque
-attribute lists with getter/setter methods, or arrays of varadic
-structures.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-What&#8217;s the behavior of an associated OpenGL or OpenCL context when
-using resources defined by the other associated context, and that
-context is destroyed?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>RESOLVED: OpenCL objects place a
-reference on the data store underlying the corresponding GL object when
-they&#8217;re created. The GL name corresponding to that data store may be
-deleted, but the data store itself remains so long as any CL object has
-a reference to it. However, destroying all GL contexts in the share
-group corresponding to a CL context results in implementation-dependent
-behavior when using a corresponding CL object, up to and including
-program termination.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-How about sharing with D3D?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>Sharing between D3D and OpenCL should use the same attribute list
-mechanism, though obviously with different parameters, and be exposed as
-a similar parallel OpenCL extension. There may be an interaction between
-that extension and this one since it&#8217;s not yet clear if it will be
-possible to create a CL context simultaneously sharing GL and D3D
-objects.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-Under what conditions will context creation fail due to sharing?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>RESOLVED: Several cross-platform failure conditions are described (GL
-context or CGL share group doesn&#8217;t exist, GL context doesn&#8217;t support
-types of GL objects, GL context
-implementation doesn&#8217;t allow sharing), but additional failures may
-result due to implementation-dependent reasons and should be added to
-this extension as such failures are discovered. Sharing between OpenCL
-and OpenGL requires integration at the driver internals level.</p></div>

-<p>
-What command queues can <strong>clEnqueueAcquire/ReleaseGLObjects</strong> be placed on?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>RESOLVED: All command queues. This restriction is enforced at context
-creation time. If any device passed to context creation cannot support
-shared CL/GL objects, context creation will fail with a
-CL_INVALID_OPERATION error.</p></div>

-<p>
-How can applications determine which command queue to place an Acquire/Release on?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>RESOLVED: The <strong>clGetGLContextInfoKHR</strong> returns either the CL device
-currently corresponding to a specified GL context (typically the display
-it&#8217;s running on), or a list of all the CL devices the specified context
-might run on (potentially useful in multiheaded / "virtual screen"
-environments). This command is not simply placed in <a href="#cl_khr_gl_sharing__memobjs">Creating OpenCL Memory Objects from OpenGL Objects</a>
-because it relies on the same property-list method of specifying a GL
-context introduced by this extension.</p></div>
-<div class="paragraph"><p>If no devices are returned, it means that the GL context exists on an
-older GPU not capable of running OpenCL, but still capable of sharing
-objects between GL running on that GPU and CL running elsewhere.</p></div>

-What is the meaning of the CL_DEVICES_FOR_GL_CONTEXT_KHR query?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>RESOLVED: The list of all CL devices that may ever be associated with a
-specific GL context. On platforms such as MacOS X, the "virtual screen"
-concept allows multiple GPUs to back a single virtual display. Similar
-functionality might be implemented on other windowing systems, such as a

OpenGL share groups and contexts are created using platform specific APIs such as EGL, CGL, WGL, and GLX. On MacOS X, an OpenCL context may be created from an OpenGL share group object using the OpenCL platform extension <strong>cl_apple_gl_sharing</strong>.  On other platforms including Microsoft Windows, Linux/Unix, and others, an OpenCL context may be created from an OpenGL context using the extension <strong>cl_khr_gl_sharing</strong>.

-<div class="paragraph"><p>In order to ensure data integrity, the application is responsible for synchronizing access to shared CL/GL objects by their respective APIs. Failure to provide such synchronization may result in race conditions and other undefined behavior including non-portability between implementations.</p></div>
-<div class="paragraph"><p>Prior to calling <strong>clEnqueueAcquireGLObjects</strong>, the application must ensure that any pending GL operations which access the objects specified in <em>mem_objects</em> have completed. This may be accomplished portably by issuing and waiting for completion of a <strong>glFinish</strong> command on all GL contexts with pending references to these objects. Implementations may offer more efficient synchronization methods; for example on some platforms calling <strong>glFlush</strong> may be sufficient, or synchronization may be implicit within a thread, or there may be vendor-specific extensions that enable placing a fence in the GL command stream and waiting for completion of that fence in the CL command queue. Note that no synchronization methods other than <strong>glFinish</strong> are portable between OpenGL implementations at this time.</p></div>
-<div class="paragraph"><p>Similarly, after calling <strong>clEnqueueReleaseGLObjects</strong>, the application is responsible for ensuring that any pending OpenCL operations which access the objects specified in <em>mem_objects</em> have completed prior to executing subsequent GL commands which reference these objects. This may be accomplished portably by calling <strong>clWaitForEvents</strong> with the event object returned by <strong>clEnqueueReleaseGLObjects,</strong> or by calling <strong>clFinish</strong>. As above, some implementations may offer more efficient methods.</p></div>
-<div class="paragraph"><p>The application is responsible for maintaining the proper order of operations if the CL and GL contexts are in separate threads.</p></div>
-<div class="paragraph"><p>If a GL context is bound to a thread other than the one in which <strong>clEnqueueReleaseGLObjects</strong> is called, changes to any of the objects in <em>mem_objects</em> may not be visible to that context without additional steps being taken by the application. For an OpenGL 3.1 (or later) context, the requirements are described in Appendix D ("Shared Objects and Multiple Contexts") of the OpenGL 3.1 Specification. For prior versions of OpenGL, the requirements are implementation-dependent.</p></div>
-<div class="paragraph"><p>Attempting to access the data store of an OpenGL object after it has been acquired by OpenCL and before it has been released will result in undefined behavior.

-<div class="paragraph"><p>If the <strong>cl_khr_gl_event</strong> extension is supported and the OpenGL context in question supports fence sync objects, completion of OpenGL commands may also be determined by placing a GL fence command after those commands using <strong>glFenceSync</strong>, creating an event from the resulting GL sync object using <strong>clCreateEventFromGLsyncKHR</strong>, and determining completion of that event object via <strong>clEnqueueAcquireGLObjects</strong>. This method may be considerably more efficient than calling <strong>glFinish</strong>, and is referred to as <em>explicit synchronization</em>. Explicit synchronization is most useful when an OpenGL context bound to another thread is accessing the memory objects.</p></div>
-<div class="paragraph"><p>If the <strong>cl_khr_gl_event</strong> extension is not supported, completion of OpenGL commands may be determined by issuing and waiting for completion of a <strong>glFinish</strong> command on all OpenGL contexts with pending references to these objects.

-<div class="paragraph"><p>Note that no synchronization method other than <strong>glFinish</strong> is portable between all OpenGL implementations and all OpenCL implementations.

-<h4 id="cl_khr_gl_event-issues">Issues</h4>
-<div class="olist arabic"><ol class="arabic">
-<li>
-<p>
-How are references between CL events and GL syncs handled?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>PROPOSED: The linked CL event places a single reference on the GL sync object. That reference is removed when the CL event is deleted. A more expensive alternative would be to reflect changes in the CL event reference count through to the GL sync.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-How are linkages to synchronization primitives in other APIs handled?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>UNRESOLVED. We will at least want to have a way to link events to EGL sync objects. There is probably no analogous DX concept. There would be an entry point for each type of synchronization primitive to be linked to, such as clCreateEventFromEGLSyncKHR.</p></div>
-<div class="paragraph"><p>An alternative is a generic clCreateEventFromExternalEvent taking an attribute list. The attribute list would include information defining the type of the external primitive and additional information (GL sync object handle, EGL display and sync object handle, etc.) specific to that type. This allows a single entry point to be reused.</p></div>
-<div class="paragraph"><p>These will probably be separate extensions following the API proposed here.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-Should the CL_EVENT_COMMAND_TYPE correspond to the type of command (fence) or the type of the linked sync object?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>PROPOSED: To the type of the linked sync object.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-Should we support both explicit and implicit synchronization?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>PROPOSED: Yes. Implicit synchronization is suitable when GL and CL are executing in the same application thread. Explicit synchronization is suitable when they are executing in different threads but the expense of glFinish is too high.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-Should this be a platform or device extension?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>PROPOSED: Platform extension. This may result in considerable under-the-hood work to implement the sync&#8594;event semantics using only the public GL API, however, when multiple drivers and devices with different GL support levels coexist in the same runtime.</p></div>
-</div></div>
-</li>
-<li>
-<p>
-Where can events generated from GL syncs be usable?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>PROPOSED: Only with clEnqueueAcquireGLObjects, and attempting to use such an event elsewhere will generate an error. There is no apparent use case for using such events elsewhere, and possibly some cost to supporting it, balanced by the cost of checking the source of events in all other commands accepting them as parameters.</p></div>

-<div class="paragraph"><p>This section describes the <strong>cl_khr_dx9_media_sharing</strong> extension. The goal of this extension is to allow applications to use media surfaces as OpenCL memory objects. This allows efficient sharing of data between OpenCL and selected adapter APIs (only DX9 for now). If this extension is supported, an OpenCL image object can be created from a media surface and the OpenCL API can be used to execute kernels that read and/or write memory objects that are media surfaces. Note that OpenCL memory objects may be created from the adapter media surface if and only if the OpenCL context has been created from that adapter.</p></div>

-<div class="openblock">
-<div class="content">

-</div></div>
-<div class="paragraph"><p>PROPOSED A: Add wording to the spec about some implementations needing the resource setup as shared:</p></div>
-<div class="paragraph"><p>"Some implementations may require the resource to be shared on the D3D10 side of the API"</p></div>
-<div class="paragraph"><p>If we do that, do we need another enum to describe this failure case?</p></div>
-<div class="paragraph"><p>PROPOSED B: Require that all implementations support both shared and non-shared resources. The restrictions prohibiting multisample textures and the flag D3D10_USAGE_IMMUTABLE guarantee software access to all shareable resources.</p></div>
-<div class="paragraph"><p>RESOLVED: Require that implementations support both D3D10_RESOURCE_MISC_SHARED being set and not set. Add the query for CL_CONTEXT_D3D10_PREFER_SHARED_RESOURCES_KHR to determine on a per-context basis which method will be faster.</p></div>

This operation is done only after all queues, memory object, programs and kernels are released, which in turn might wait for all ongoing operations to complete. However, there are cases in which a fast release is required, or release operation cannot be done, as commands are stuck in mid execution. An example of the first case can be program termination due to exception, or quick shutdown due to low power. Examples of the second case are when a kernel is running too long, or gets stuck, or it may result from user action which makes the results of the computation unnecessary.</p></div>

-This extension does not support reference counting of the images, so the onus is on the application to behave sensibly and not release the underlying cl_mem object while the EGLImage is still being used.

-What should happen for YUV color-space conversion, multi plane images, and chroma-siting, and channel mapping?
-</p>
-<div class="openblock">
-<div class="content">
-<div class="paragraph"><p>RESOLVED: YUV is no longer explicitly described in this extension. Before this removal the behavior was dependent on the platform. This extension explicitly leaves the YUV layout to the platform and EGLImage source extension (i.e. is implementation specific). Colorspace conversion must be applied by the application using a color conversion matrix.</p></div>
-<div class="paragraph"><p>The expected extension path if YUV color-space conversion is to be supported is to introduce a YUV image type and provide overloaded versions of the read_image built-in functions.</p></div>
-<div class="paragraph"><p>Getting image information for a YUV image should return the original image size (non quantized size) when all of Y U and V are present in the image. If the planes have been separated then the actual dimensionality of the separated plane should be reported. For example with YUV 4:2:0 (NV12) with a YUV image of 256x256, the Y only image would return 256x256 whereas the UV only image would return 128x128.</p></div>

The sync object in turn refers to a fence command executing in an EGL client API command stream. This provides another method of coordinating sharing of EGL / EGL client API objects with OpenCL. Completion of EGL / EGL client API commands may be determined by placing an EGL fence command after commands using eglCreateSyncKHR, creating an event from the resulting EGL sync object using clCreateEventFromEGLSyncKHR and then specifying it in the <em>event_wait_list</em> of a clEnqueueAcquire*** command. This method may be considerably more efficient than calling operations like glFinish, and is referred to as <em>explicit synchronization</em>.

Explicit synchronization is most useful when an EGL client API context bound to another thread is accessing the memory objects."</p></div>

-<h2 id="_introduction">1. Introduction</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>Modern processor architectures have embraced parallelism as an important
-pathway to increased performance. Facing technical challenges with
-higher clock speeds in a fixed power envelope, Central Processing Units
-(CPUs) now improve performance by adding multiple cores. Graphics
-Processing Units (GPUs) have also evolved from fixed function rendering
-devices into programmable parallel processors. As todays computer
-systems often include highly parallel CPUs, GPUs and other types of
-processors, it is important to enable software developers to take full
-advantage of these heterogeneous processing platforms.
-<br>
-<br>
-Creating applications for heterogeneous parallel processing platforms is
-challenging as traditional programming approaches for multi-core CPUs
-and GPUs are very different. CPU-based parallel programming models are
-typically based on standards but usually assume a shared address space
-and do not encompass vector operations. General purpose GPU
-programming models address complex memory hierarchies and vector
-operations but are traditionally platform-, vendor- or
-hardware-specific. These limitations make it difficult for a developer
-to access the compute power of heterogeneous CPUs, GPUs and other types
-of processors from a single, multi-platform source code base. More than
-ever, there is a need to enable software developers to effectively take
-full advantage of heterogeneous processing platforms  from high
-performance compute servers, through desktop computer systems to
-handheld devices - that include a diverse mix of parallel CPUs, GPUs and
-other processors such as DSPs and the Cell/B.E. processor.
-<br>
-<br>
-<strong>OpenCL</strong> (Open Computing Language) is an open royalty-free standard for
-general purpose parallel programming across CPUs, GPUs and other
-processors, giving software developers portable and efficient access to
-the power of these heterogeneous processing platforms.
-<br>
-<br>
-OpenCL supports a wide range of applications, ranging from embedded and
-consumer software to HPC solutions, through a low-level,
-high-performance, portable abstraction. By creating an efficient,
-close-to-the-metal programming interface, OpenCL will form the
-foundation layer of a parallel computing ecosystem of
-platform-independent tools, middleware and applications. OpenCL is
-particularly suited to play an increasingly significant role in emerging
-interactive graphics applications that combine general parallel compute
-algorithms with graphics rendering pipelines.
-<br>
-<br>
-OpenCL consists of an API for coordinating parallel computation across
-heterogeneous processors; and a cross-platform intermediate language
-with a well-specified computation environment. The OpenCL standard:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Supports both data- and
-task-based parallel programming models
-</p>
-</li>
-<li>
-<p>
-Utilizes a portable and
-self-contained intermediate representation with support for parallel
-execution
-</p>
-</li>
-<li>
-<p>
-Defines consistent
-numerical requirements based on IEEE 754
-</p>
-</li>
-<li>
-<p>
-Defines a configuration
-profile for handheld and embedded devices
-</p>
-</li>
-<li>
-<p>
-Efficiently interoperates
-with OpenGL, OpenGL ES and other graphics APIs
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>This document begins with an overview of basic concepts and the
-architecture of OpenCL, followed by a detailed description of its
-execution model, memory model and synchronization support. It then
-discusses the OpenCL__platform and runtime API. Some examples are given
-that describe sample compute use-cases and how they would be written in
-OpenCL. The specification is divided into a core specification that any
-OpenCL compliant implementation must support; a handheld/embedded
-profile which relaxes the OpenCL compliance requirements for handheld
-and embedded devices; and a set of optional extensions that are likely
-to move into the core specification in later revisions of the OpenCL
-specification.</p></div>

-<h2 id="_glossary">2. Glossary</h2>
-<div class="sectionbody">
-<div class="paragraph"><p><strong>Application</strong>: The combination of the program running on the host and
-OpenCL devices.
-<br>
-<br>
-<strong>Acquire semantics</strong>: One of the memory order semantics defined for
-synchronization operations.  Acquire semantics apply to atomic
-operations that load from memory.  Given two units of execution, <strong>A</strong> and
-<strong>B</strong>, acting on a shared atomic object <strong>M</strong>, if <strong>A</strong> uses an atomic load of
-<strong>M</strong> with acquire semantics to synchronize-with an atomic store to <strong>M</strong> by
-<strong>B</strong> that used release semantics, then <strong>A</strong>'s atomic load will occur before
-any subsequent operations by <strong>A</strong>.  Note that the memory orders
-<em>release</em>, <em>sequentially consistent</em>, and <em>acquire_release</em> all include
-<em>release semantics</em> and effectively pair with a load using acquire
-semantics.
-<br>
-<br>
-<strong>Acquire release semantics</strong>: A memory order semantics for
-synchronization operations (such as atomic operations) that has the
-properties of both acquire and release memory orders. It is used with
-read-modify-write operations.
-<br>
-<br>
-<strong>Atomic operations</strong>: Operations that at any point, and from any
-perspective, have either occurred completely, or not at all. Memory
-orders associated with atomic operations may constrain the visibility of
-loads and stores with respect to the atomic operations (see <em>relaxed
-semantics</em>, <em>acquire semantics</em>, <em>release semantics</em> or <em>acquire release
-semantics</em>).
-<br>
-<br>
-<strong>Blocking and Non-Blocking Enqueue API calls</strong>: A <em>non-blocking enqueue
-API call</em> places a <em>command</em> on a <em>command-queue</em> and returns
-immediately to the host. The <em>blocking-mode enqueue API calls</em> do not
-return to the host until the command has completed.
-<br>
-<br>
-<strong>Barrier</strong>: There are three types of <em>barriers</em>  a command-queue barrier,
-a work-group barrier and a sub-group barrier.</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-The OpenCL API provides a
-function to enqueue a <em>command-queue</em> <em>barrier</em> command. This <em>barrier</em>
-command ensures that all previously enqueued commands to a command-queue
-have finished execution before any following <em>commands</em> enqueued in the
-<em>command-queue</em> can begin execution.
-</p>
-</li>
-<li>
-<p>
-The OpenCL kernel
-execution model provides built-in <em>work-group barrier</em> functionality.
-This <em>barrier</em> built-in function can be used by a <em>kernel</em> executing on
-a <em>device</em> to perform synchronization between <em>work-items</em> in a
-<em>work-group</em> executing the <em>kernel</em>. All the <em>work-items</em> of a
-<em>work-group</em> must execute the <em>barrier</em> construct before any are allowed
-to continue execution beyond the <em>barrier</em>.
-</p>
-</li>
-<li>
-<p>
-The OpenCL kernel
-execution model provides built-in <em>sub-group barrier</em> functionality.
-This <em>barrier</em> built-in function can be used by a <em>kernel</em> executing on
-a <em>device</em> to perform synchronization between <em>work-items</em> in a
-<em>sub-group</em> executing the <em>kernel</em>. All the <em>work-items</em> of a
-<em>sub-group</em> must execute the <em>barrier</em> construct before any are allowed
-to continue execution beyond the <em>barrier</em>.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p><strong>Buffer Object</strong>: A memory object that stores a linear collection of
-bytes. Buffer objects are accessible using a pointer in a <em>kernel</em>
-executing on a <em>device</em>. Buffer objects can be manipulated by the host
-using OpenCL API calls. A <em>buffer object</em> encapsulates the following
-information:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Size in bytes.
-</p>
-</li>
-<li>
-<p>
-Properties that describe
-usage information and which region to allocate from.
-</p>
-</li>
-<li>
-<p>
-Buffer data.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p><strong>Built-in Kernel</strong>: A <em>built-in kernel</em> is a <em>kernel</em> that is executed on
-an OpenCL <em>device</em> or <em>custom device</em> by fixed-function hardware or in
-firmware. <em>Applications</em> can query the <em>built-in kernels</em> supported by
-a <em>device</em> or <em>custom device</em>. A <em>program object</em> can only contain
-<em>kernels</em> written in OpenCL C or <em>built-in kernels</em> but not both. See
-also <em>Kernel</em> and <em>Program</em>.
-<br>
-<br>
-<strong>Child kernel</strong>: see <em>device-side enqueue.</em>
-<br>
-<br>
-<strong>Command</strong>: The OpenCL operations that are submitted to a <em>command-queue</em>
-for execution. For example, OpenCL commands issue kernels for execution
-on a compute device, manipulate memory objects, etc.
-<br>
-<br>
-<strong>Command-queue</strong>: An object that holds <em>commands</em> that will be executed on
-a specific <em>device</em>. The <em>command-queue</em> is created on a specific
-<em>device</em> in a <em>context</em>. <em>Commands</em> to a <em>command-queue</em> are queued
-in-order but may be executed in-order or out-of-order. <em>Refer to
-In-order Execution_and_Out-of-order Execution</em>.
-<br>
-<br>
-<strong>Command-queue Barrier</strong>. See <em>Barrier</em>.
-<br>
-<br>
-<strong>Command synchronization</strong>: Constraints on the order that commands are
-launched for execution on a device defined in terms of the
-synchronization points that occur between commands in host
-command-queues and between commands in device-side command-queues. See
-<em>synchronization points</em>.
-<br>
-<br>
-<strong>Complete</strong>: The final state in the six state model for the execution of
-a command. The transition into this state occurs is signaled through
-event objects or callback functions associated with a command.
-<br>
-<br>
-<strong>Compute Device Memory</strong>: This refers to one or more memories attached
-to the compute device.
-<br>
-<br>
-<strong>Compute Unit</strong>: An OpenCL <em>device</em> has one or more <em>compute units</em>. A
-<em>work-group</em> executes on a single <em>compute unit</em>. A <em>compute unit</em> is
-composed of one or more <em>processing elements</em> and <em>local memory</em>. A
-<em>compute unit</em> may also include dedicated texture filter units that can
-be accessed by its processing elements.
-<br>
-<br>
-<strong>Concurrency</strong>: A property of a system in which a set of tasks in a system
-can remain active and make progress at the same time. To utilize
-concurrent execution when running a program, a programmer must identify
-the concurrency in their problem, expose it within the source code, and
-then exploit it using a notation that supports concurrency.
-<br>
-<br>
-<strong>Constant Memory</strong>: A region of <em>global memory</em> that remains constant
-during the execution of a <em>kernel</em>. The <em>host</em> allocates and
-initializes memory objects placed into <em>constant memory</em>.</p></div>
-<div class="paragraph"><p><strong>Context</strong>: The environment within which the kernels execute and the
-domain in which synchronization and memory management is defined. The
-<em>context</em> includes a set of <em>devices</em>, the memory accessible to those
-<em>devices</em>, the corresponding memory properties and one or more
-<em>command-queues</em> used to schedule execution of a <em>kernel(s)</em> or
-operations on <em>memory objects</em>.
-<br>
-<br>
-<strong>Control flow</strong>: The flow of instructions executed by a work-item.
-Multiple logically related work items may or may not execute the same
-control flow. The control flow is said to be <em>converged</em> if all the
-work-items in the set execution the same stream of instructions. In a
-<em>diverged</em> control flow, the work-items in the set execute different
-instructions. At a later point, if a diverged control flow becomes
-converged, it is said to be a re-converged control flow.
-<br>
-<br>
-<strong>Converged control flow</strong>: see <strong>control flow</strong>.
-<br>
-<br>
-<strong>Custom Device</strong>: An OpenCL <em>device</em> that fully implements the OpenCL
-Runtime but does not support <em>programs</em> written in OpenCL C.  A custom
-device may be specialized non-programmable hardware that is very power
-efficient and performant for directed tasks or hardware with limited
-programmable capabilities such as specialized DSPs. Custom devices are
-not OpenCL conformant. Custom devices may support an online compiler.  
-Programs for custom devices can be created using the OpenCL runtime APIs
-that allow OpenCL programs to be created from source (if an online
-compiler is supported) and/or binary, or from <em>built-in
-kernels_supported by the _device</em>.  See also <em>Device</em>.
-<br>
-<br>
-<strong>Data Parallel Programming Model</strong>: Traditionally, this term refers to a
-programming model where concurrency is expressed as instructions from a
-single program applied to multiple elements within a set of data
-structures.  The term has been generalized in OpenCL to refer to a model
-wherein a set of  instructions from a single program are applied
-concurrently to each point within an abstract domain of indices.
-<br>
-<br>
-<strong>Data race</strong>: The execution of a program contains a data race if it
-contains two actions in different work items or host threads where (1)
-one action modifies a memory location and the other action reads or
-modifies the same memory location, and (2) at least one of these actions
-is not atomic, or the corresponding memory scopes are not inclusive, and
-(3) the actions are global actions unordered by the
-global-happens-before relation or are local actions unordered by the
-local-happens before relation.
-<br>
-<br>
-<strong>Deprecation</strong>: existing features are marked as deprecated if their usage is not recommended as that feature is being de-emphasized, superseded and may be removed from a future version of the specification.[BA2] 
-<br>
-<br>
-<strong>Device</strong>: A <em>device</em> is a collection of <em>compute units</em>. A
-<em>command-queue</em> is used to queue <em>commands</em> to a <em>device</em>. Examples of
-<em>commands</em> include executing <em>kernels</em>, or reading and writing <em>memory
-objects</em>. OpenCL devices typically correspond to a GPU, a multi-core
-CPU, and other processors such as DSPs and the Cell/B.E. processor.
-<br>
-<br>
-<strong>Device-side enqueue</strong>: A mechanism whereby a kernel-instance is enqueued
-by a kernel-instance running on a device without direct involvement by
-the host program. This produces <em>nested parallelism</em>; i.e. additional
-levels of concurrency are nested inside a running kernel-instance. The
-kernel-instance executing on a device (the <em>parent kernel</em>) enqueues a
-kernel-instance (the <em>child kernel</em>) to a device-side command queue.
-Child and parent kernels execute asynchronously though a parent kernel
-does not complete until all of its child-kernels have completed.
-<br>
-<br>
-<strong>Diverged control flow</strong>: see <em>control flow</em>.
-<br>
-<br>
-<strong>Ended</strong>: The fifth state in the six state model for the execution of a
-command. The transition into this state occurs when execution of a
-command has ended. When a Kernel-enqueue command ends, all of the
-work-groups associated with that command have finished their execution.
-<br>
-<br>
-<strong>Event Object</strong>: An <em>event</em> <em>object_encapsulates the status of an
-operation such as a _command</em>. It can be used to synchronize operations
-in a context.
-<br>
-<br>
-<strong>Event Wait List</strong>: An <em>event wait list</em> is a list of <em>event objects</em> that
-can be used to control when a particular <em>command</em> begins execution.
-<br>
-<br>
-<strong>Fence</strong>: A memory ordering operation without an associated atomic
-object. A fence can use the <em>acquire semantics, release semantics</em>, or
-<em>acquire release semantics</em>.
-<br>
-<br>
-<strong>Framework</strong>: A software system that contains the set of components to
-support software development and execution. A <em>framework</em> typically
-includes libraries, APIs, runtime systems, compilers, etc.
-<br>
-<br>
-<strong>Generic address space</strong>: An address space that include the <em>private</em>,
-<em>local</em>, and <em>global</em> address spaces available to a device. The generic
-address space supports conversion of pointers to and from private, local
-and global address spaces, and hence lets a programmer write a single
-function that at compile time can take arguments from any of the three
-named address spaces.
-<br>
-<br>
-<strong>Global Happens before</strong>: see <em>happens before</em>.
-<br>
-<br>
-<strong>Global ID</strong>: A <em>global ID</em> is used to uniquely identify a <em>work-item</em> and
-is derived from the number of <em>global work-items</em> specified when
-executing a <em>kernel</em>. The <em>global ID</em> is a N-dimensional value that
-starts at (0, 0,  0). See also <em>Local ID</em>.
-<br>
-<br>
-<strong>Global Memory</strong>: A memory region accessible to all <em>work-items</em> executing
-in a <em>context</em>. It is accessible to the <em>host</em> using <em>commands</em> such as
-read, write and map. <em>Global memory</em> is included within the <em>generic
-address space</em> that includes the private and local address spaces.
-<br>
-<br>
-<strong>GL share group</strong>: A <em>GL share group</em> object manages shared OpenGL or
-OpenGL ES resources
-such as textures, buffers, framebuffers, and renderbuffers and is
-associated with one or more GL context objects. The <em>GL share group</em> is
-typically an opaque object and not directly accessible.
-<br>
-<br>
-<strong>Handle</strong>: An opaque type that references an <em>object</em> allocated by
-OpenCL. Any operation on an <em>object</em> occurs by reference to that
-objects handle.
-<br>
-<br>
-<strong>Happens before</strong>: An ordering relationship between operations that
-execute on multiple units of execution. If an operation A happens-before
-operation B then A must occur before B; in particular, any value written
-by A will be visible to B.We define two separate happens before
-relations: <em>global-happens-before</em> and <em>local-happens-before</em>. These are
-defined in section 3.3.6.
-<br>
-<br>
-<strong>Host</strong>: The <em>host</em> interacts with the <em>context</em> using the OpenCL API.
-<br>
-<br>
-<strong>Host-thread</strong>: the unit of execution that executes the statements in the
-Host program.
-<br>
-<br>
-<strong>Host pointer</strong>: A pointer to memory that is in the virtual address space
-on the <em>host</em>.
-<br>
-<br>
-<strong>Illegal</strong>: Behavior of a system that is explicitly not allowed and will
-be reported as an error when encountered by OpenCL.
-<br>
-<br>
-<strong>Image Object</strong>: A <em>memory object</em> that stores a two- or three-
-dimensional structured array. Image data can only be accessed with read
-and write functions. The read functions use a <em>sampler</em>.
-<br>
-<br>
-The <em>image object</em> encapsulates the following information:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Dimensions of the image.
-</p>
-</li>
-<li>
-<p>
-Description of each
-element in the image.
-</p>
-</li>
-<li>
-<p>
-Properties that describe
-usage information and which region to allocate from.
-</p>
-</li>
-<li>
-<p>
-Image data.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>The elements of an image are selected from a list of predefined image
-formats.
-<br>
-<br>
-<strong>Implementation Defined</strong>: Behavior that is explicitly allowed to vary
-between conforming implementations of OpenCL. An OpenCL implementor is
-required to document the implementation-defined behavior.
-<br>
-<br>
-<strong>Independent Forward Progress</strong>: If an entity supports independent forward
-progress, then if it is otherwise not dependent on any actions due to be
-performed by any other entity (for example it does not wait on a lock
-held by, and thus that must be released by, any other entity), then its
-execution cannot be blocked by the execution of any other entity in the
-system (it will not be starved). Work items in a subgroup, for example,
-typically do not support independent forward progress, so one work item
-in a subgroup may be completely blocked (starved) if a different work
-item in the same subgroup enters a spin loop.
-<br>
-<br>
-<strong>In-order Execution</strong>: A model of execution in OpenCL where the <em>commands</em>
-in a <em>command-queue_ are executed in order of submission with each
-_command</em> running to completion before the next one begins. See
-Out-of-order Execution.
-<br>
-<br>
-<strong>Intermediate Language</strong>: A lower-level language that may be used to
-create programs. SPIR-V is a required IL for OpenCL 2.2 runtimes.
-Additional ILs may be accepted on an implementation-defined basis.
-<br>
-<br>
-<strong>Kernel</strong>: A <em>kernel</em> is a function declared in a <em>program</em> and executed
-on an OpenCL <em>device</em>. A <em>kernel</em> is identified by the kernel or
-kernel qualifier applied to any function defined in a <em>program</em>.
-<br>
-<br>
-<strong>Kernel-instance</strong>: The work carried out by an OpenCL program occurs
-through the execution of kernel-instances on devices. The kernel
-instance is the <em>kernel object</em>, the values associated with the
-arguments to the kernel, and the parameters that define the <em>NDRange</em>
-index space.
-<br>
-<br>
-<strong>Kernel Object</strong>: A <em>kernel object</em> encapsulates a specific <em>kernel
-function declared in a <em>program</em> and the argument values to be used when
-executing this </em>kernel function.
-<br>
-<br>
-<strong>Kernel Language</strong>: A language that is used to create source code for kernel.
-Supported kernel languages include OpenCL C, OpenCL C++, and OpenCL dialect of SPIR-V.
-<br>
-<br>
-<strong>Launch</strong>: The transition of a command from the <em>submitted</em> state to the
-<em>ready</em> state. See <em>Ready</em>.
-<br>
-<br>
-<strong>Local ID</strong>: A <em>local ID</em> specifies a unique <em>work-item ID</em> within a given
-<em>work-group</em> that is executing a <em>kernel</em>. The <em>local ID</em> is a
-N-dimensional value that starts at (0, 0,  0). See also <em>Global ID</em>.
-<br>
-<br>
-<strong>Local Memory</strong>: A memory region associated with a <em>work-group</em> and
-accessible only by <em>work-items</em> in that <em>work-group</em>. <em>Local memory</em> is
-included within the <em>generic address space</em> that includes the private
-and global address spaces.
-<br>
-<br>
-<strong>Marker</strong>: A <em>command</em> queued in a <em>command-queue</em> that can be used to
-tag all <em>commands</em> queued before the <em>marker</em> in the <em>command-queue</em>.
-The <em>marker</em> command returns an <em>event</em> which can be used by the
-<em>application</em> to queue a wait on the marker event i.e. wait for all
-commands queued before the <em>marker</em> command to complete.
-<br>
-<br>
-<strong>Memory Consistency Model</strong>: Rules that define which values are observed
-when multiple units of execution load data from any shared memory plus
-the synchronization operations that constrain the order of memory
-operations and define synchronization relationships. The memory
-consistency model in OpenCL is based on the memory model from the ISO
-C11 programming language.
-<br>
-<br>
-<strong>Memory Objects</strong>: A <em>memory object</em> is a handle to a reference counted
-region of <em>global memory</em>. Also see_Buffer Object_and_Image Object_.
-<br>
-<br>
-<strong>Memory Regions (or Pools)</strong>: A distinct address space in OpenCL. <em>Memory
-regions</em> may overlap in physical memory though OpenCL will treat them as
-logically distinct. The <em>memory regions</em> are denoted as <em>private</em>,
-<em>local</em>, <em>constant,</em> and <em>global</em>.
-<br>
-<br>
-<strong>Memory Scopes</strong>: These memory scopes define a hierarchy of visibilities
-when analyzing the ordering constraints of memory operations. They are
-defined by the values of the memory_scope enumeration constant. Current
-values are <strong>memory_scope_work_item</strong>(memory constraints only apply to a
-single work-item and in practice apply only to image operations)<strong>,
-memory_scope_sub_group</strong> (memory-ordering constraints only apply to
-work-items executing in a sub-group), <strong>memory_scope_work_group</strong>
-(memory-ordering constraints only apply to work-items executing in a
-work-group), <strong>memory_scope_device</strong> (memory-ordering constraints only
-apply to work-items executing on a single device) and
-<strong>memory_scope_all_svm_devices</strong> (memory-ordering constraints only apply
-to work-items executing across multiple devices and when using shared
-virtual memory).
-<br>
-<br>
-<strong>Modification Order</strong>:All modifications to a particular atomic object M
-occur in some particular <strong>total order</strong>, called the <strong>modification
-order</strong> of M. If A and B are modifications of an atomic object M, and A
-happens-before B, then A shall precede B in the modification order of M.
-Note that the modification order of an atomic object M is independent of
-whether M is in local or global memory.
-<br>
-<br>
-<strong>Nested Parallelism</strong>: See <em>device-side enqueue</em>.
-<br>
-<br>
-<strong>Object</strong>: Objects are abstract representation of the resources that can
-be manipulated by the OpenCL API. Examples include <em>program objects</em>,
-<em>kernel objects</em>, and <em>memory objects</em>.
-<br>
-<br>
-<strong>Out-of-Order Execution</strong>: A model of execution in which <em>commands</em> placed
-in the <em>work queue</em> may begin and complete execution in any order
-consistent with constraints imposed by <em>event wait
-lists_and_command-queue barrier</em>. See <em>In-order Execution</em>.
-<br>
-<br>
-<strong>Parent device</strong>: The OpenCL <em>device</em> which is partitioned to create
-<em>sub-devices</em>. Not all <em>parent devices_are _root devices</em>. A <em>root
-device</em> might be partitioned and the <em>sub-devices</em> partitioned again.
-In this case, the first set of <em>sub-devices</em> would be <em>parent devices</em>
-of the second set, but not the <em>root devices</em>. Also see <em>device</em>,
-<em>parent device</em> and <em>root device</em>.
-<br>
-<br>
-<strong>Parent kernel</strong>: see <em>device-side enqueue</em>.
-<br>
-<br>
-<strong>Pipe</strong>: The <em>pipe</em> memory object conceptually is an ordered sequence of
-data items. A pipe has two endpoints: a write endpoint into which data
-items are inserted, and a read endpoint from which data items are
-removed. At any one time, only one kernel instance may write into a
-pipe, and only one kernel instance may read from a pipe. To support the
-producer consumer design pattern, one kernel instance connects to the
-write endpoint (the producer) while another kernel instance connects to
-the reading endpoint (the consumer).
-<br>
-<br>
-<strong>Platform</strong>: The <em>host</em> plus a collection of <em>devices</em> managed by the
-OpenCL <em>framework</em> that allow an application to share <em>resources</em> and
-execute <em>kernels</em> on <em>devices</em> in the <em>platform</em>.
-<br>
-<br>
-<strong>Private Memory</strong>: A region of memory private to a <em>work-item</em>. Variables
-defined in one <em>work-items</em> <em>private memory</em> are not visible to another
-<em>work-item</em>.
-<br>
-<br>
-<strong>Processing Element</strong>: A virtual scalar processor. A work-item may
-execute on one or more processing elements.
-<br>
-<br>
-<strong>Program</strong>: An OpenCL <em>program</em> consists of a set of <em>kernels</em>.
-<em>Programs</em> may also contain auxiliary functions called by the <em>_kernel
-functions and constant data.
-<br>
-<br>
-<strong>Program Object</strong>: A _program object</em> encapsulates the following
-information:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-A reference to an
-associated <em>context</em>.
-</p>
-</li>
-<li>
-<p>
-A <em>program</em> source or
-binary.
-</p>
-</li>
-<li>
-<p>
-The latest successfully
-built program executable, the list of <em>devices</em> for which the program
-executable is built, the build options used and a build log.
-</p>
-</li>
-<li>
-<p>
-The number of <em>kernel
-objects</em> currently attached.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p><strong>Queued</strong>: The first state in the six state model for the execution of a
-command. The transition into this state occurs when the command is
-enqueued into a command-queue.
-<br>
-<br>
-<strong>Ready</strong>: The third state in the six state model for the execution of a
-command. The transition into this state occurs when pre-requisites
-constraining execution of a command have been met; i.e. the command has
-been launched. When a Kernel-enqueue command is launched, work-groups
-associated with the command are placed in a devices work-pool from
-which they are scheduled for execution.
-<br>
-<br>
-<strong>Re-converged Control Flow</strong>: see <em>control flow</em>.
-<br>
-<br>
-<strong>Reference Count</strong>: The life span of an OpenCL object is determined by its
-<em>reference count_an internal count of the number of references to the
-object. When you create an object in OpenCL, its _reference count</em> is
-set to one. Subsequent calls to the appropriate <em>retain</em> API (such as
-clRetainContext, clRetainCommandQueue) increment the <em>reference count</em>.
-Calls to the appropriate <em>release</em> API (such as clReleaseContext,
-clReleaseCommandQueue) decrement the <em>reference count</em>.
-Implementations may also modify the <em>reference count</em>, e.g. to track
-attached objects or to ensure correct operation of in-progress or
-scheduled activities. The object becomes inaccessible to host code when
-the number of <em>release</em> operations performed matches the number of
-<em>retain</em> operations plus the allocation of the object. At this point the
-reference count may be zero but this is not guaranteed.
-<br>
-<br>
-<strong>Relaxed Consistency</strong>: A memory consistency model in which the contents
-of memory visible to different <em>work-items</em> or <em>commands</em> may be
-different except at a <em>barrier</em> or other explicit synchronization
-points.
-<br>
-<br>
-<strong>Relaxed Semantics</strong>: A memory order semantics for atomic operations that
-implies no order constraints. The operation is <em>atomic</em> but it has no
-impact on the order of memory operations.
-<br>
-<br>
-<strong>Release Semantics</strong>: One of the memory order semantics defined for
-synchronization operations.  Release semantics apply to atomic
-operations that store to memory.  Given two units of execution, <strong>A</strong> and
-<strong>B</strong>, acting on a shared atomic object <strong>M</strong>, if <strong>A</strong> uses an atomic store
-of <strong>M</strong> with release semantics to synchronize-with an atomic load to <strong>M</strong>
-by <strong>B*that used acquire semantics, then *A*s atomic store will occur
-<em>after</em> any prior operations by *A</strong>. Note that the memory orders
-<em>acquire</em>, <em>sequentialy consistent</em>, and <em>acquire_release</em> all include
-<em>acquire semantics</em> and effectively pair with a store using release
-semantics.
-<br>
-<br>
-<strong>Remainder work-groups</strong>: When the work-groups associated with a
-kernel-instance are defined, the sizes of a work-group in each dimension
-may not evenly divide the size of the NDRange in the corresponding
-dimensions. The result is a collection of work-groups on the boundaries
-of the NDRange that are smaller than the base work-group size. These are
-known as <em>remainder work-groups</em>.
-<br>
-<br>
-<strong>Running</strong>: The fourth state in the six state model for the execution of
-a command. The transition into this state occurs when the execution of
-the command starts. When a Kernel-enqueue command starts, one or more
-work-groups associated with the command start to execute.
-<br>
-<br>
-<strong>Root device</strong>: A <em>root device</em> is an OpenCL <em>device</em> that has not been
-partitioned. Also see <em>device</em>, <em>parent device</em> and <em>root device</em>.
-<br>
-<br>
-<strong>Resource</strong>: A class of <em>objects</em> defined by OpenCL. An instance of a
-<em>resource</em> is an <em>object</em>. The most common <em>resources</em> are the
-<em>context</em>, <em>command-queue</em>, <em>program objects</em>, <em>kernel objects</em>, and
-<em>memory objects</em>. Computational resources are hardware elements that
-participate in the action of advancing a program counter. Examples
-include the <em>host</em>, <em>devices</em>, <em>compute units</em> and <em>processing
-elements</em>.
-<br>
-<br>
-<strong>Retain</strong>, Release: The action of incrementing (retain) and decrementing
-(release) the reference count using an OpenCL <em>object</em>. This is a book
-keeping functionality to make sure the system doesnt remove an <em>object</em>
-before all instances that use this <em>object</em> have finished. Refer to
-<em>Reference Count</em>.
-<br>
-<br>
-<strong>Sampler</strong>: An <em>object</em> that describes how to sample an image when the
-image is read in the <em>kernel</em>. The image read functions take a
-<em>sampler</em> as an argument. The <em>sampler</em> specifies the image
-addressing-mode i.e. how out-of-range image coordinates are handled, the
-filter mode, and whether the input image coordinate is a normalized or
-unnormalized value.
-<br>
-<br>
-<strong>Scope inclusion</strong>: Two actions <strong>A</strong> and <strong>B</strong> are defined to have an
-inclusive scope if they have the same scope <strong>P</strong> such that: (1) if <strong>P</strong> is
-memory_scope_sub_group, and <strong>A</strong> and <strong>B</strong> are executed by work-items
-within the same sub-group, or (2) if <strong>P</strong> is memory_scope_work_group, and
-<strong>A</strong> and <strong>B</strong> are executed by work-items within the same work-group, or
-(3) if <strong>P</strong> is memory_scope_device, and <strong>A</strong> and <strong>B</strong> are executed by
-work-items on the same device, or (4) if <strong>P</strong> is
-memory_scope_all_svm_devices, if <strong>A</strong> and <strong>B</strong> are executed by host
-threads or by work-items on one or more devices that can share SVM
-memory with each other and the host process.
-<br>
-<br>
-<strong>Sequenced before</strong>: A relation between evaluations executed by a single
-unit of execution. Sequenced-before is an asymmetric, transitive,
-pair-wise relation that induces a partial order between evaluations.
-Given any two evaluations A and B, if A is sequenced-before B, then the
-execution of A shall precede the execution of B.
-<br>
-<br>
-<strong>Sequential consistency</strong>: Sequential consistency interleaves the steps
-executed by each unit of execution. Each access to a memory location
-sees the last assignment to that location in that interleaving.
-<br>
-<br>
-<strong>Sequentially consistent semantics</strong>: One of the memory order semantics
-defined for synchronization operations. When using
-sequentially-consistent synchronization operations, the loads and stores
-within one unit of execution appear to execute in program order (i.e.,
-the sequenced-before order), and loads and stores from different units
-of execution appear to be simply interleaved.
-<br>
-<br>
-<strong>Shared Virtual Memory (SVM)</strong>: An address space exposed to both the host
-and the devices within a context. SVM causes addresses to be meaningful
-between the host and all of the devices within a context and therefore
-supports the use of pointer based data structures in OpenCL kernels. It
-logically extends a portion of the global memory into the host address
-space therefore giving work-items access to the host address space.
-There are three types of SVM in OpenCL <strong>Coarse-Grained buffer SVM</strong>:
-Sharing occurs at the granularity of regions of OpenCL buffer memory
-objects. <strong>Fine-Grained buffer SVM</strong>: Sharing occurs at the granularity
-of individual loads/stores into bytes within OpenCL buffer memory
-objects. <strong>Fine-Grained system SVM</strong>: Sharing occurs at the granularity of
-individual loads/stores into bytes occurring anywhere within the host
-memory.
-<br>
-<br>
-<strong>SIMD</strong>: Single Instruction Multiple Data. A programming model where a
-<em>kernel</em> is executed concurrently on multiple <em>processing elements</em> each
-with its own data and a shared program counter. All <em>processing
-elements</em> execute a strictly identical set of instructions.
-<br>
-<br>
-<strong>Specialization constants</strong>: Specialization is intended for constant
-objects that will not have known constant values until after initial
-generation of a SPIR-V module. Such objects are called specialization
-constants. Application might provide values for
-the specialization constants that will be used when SPIR-V program is
-built. Specialization constants that do not receive a value from an
-application shall use default value as defined in SPIR-V specification.
-<br>
-<br>
-<strong>SPMD</strong>: Single Program Multiple Data. A programming model where a
-<em>kernel</em> is executed concurrently on multiple <em>processing elements</em> each
-with its own data and its own program counter. Hence, while all
-computational resources run the same <em>kernel</em> they maintain their own
-instruction counter and due to branches in a <em>kernel</em>, the actual
-sequence of instructions can be quite different across the set of
-<em>processing elements</em>.
-<br>
-<br>
-<strong>Sub-device</strong>: An OpenCL <em>device</em> can be partitioned into multiple
-<em>sub-devices</em>. The new <em>sub-devices</em> alias specific collections of
-compute units within the parent <em>device</em>, according to a partition
-scheme. The <em>sub-devices</em> may be used in any situation that their
-parent <em>device</em> may be used. Partitioning a <em>device</em> does not destroy
-the parent <em>device</em>, which may continue to be used along side and
-intermingled with its child <em>sub-devices</em>. Also see <em>device</em>, <em>parent
-device</em> and <em>root device</em>.
-<br>
-<br>
-<strong>Sub-group</strong>: Sub-groups are an implementation-dependent grouping of
-work-items within a work-group.   The size and number of sub-groups is
-implementation-defined.
-<br>
-<br>
-<strong>Sub-group Barrier</strong>. See <em>Barrier</em>.
-<br>
-<br>
-<strong>Submitted</strong>: The second state in the six state model for the execution
-of a command. The transition into this state occurs when the command is
-flushed from the command-queue and submitted for execution on the
-device. Once submitted, a programmer can assume a command will execute
-once its prerequisites have been met.
-<br>
-<br>
-<strong>SVM Buffer</strong>: A memory allocation enabled to work with Shared Virtual
-Memory (SVM). Depending on how the SVM buffer is created, it can be a
-coarse-grained or fine-grained SVM buffer. Optionally it may be wrapped
-by a Buffer Object. See <em>Shared Virtual Memory (SVM)</em>.
-<br>
-<br>
-<strong>Synchronization</strong>: Synchronization refers to mechanisms that constrain
-the order of execution and the visibility of memory operations between
-two or more units of execution.
-<br>
-<br>
-<strong>Synchronization operations</strong>: Operations that define memory order
-constraints in a program. They play a special role in controlling how
-memory operations in one unit of execution (such as work-items or, when
-using SVM a host thread) are made visible to another. Synchronization
-operations in OpenCL include <em>atomic operations</em> and <em>fences</em>.
-<br>
-<br>
-<strong>Synchronization point</strong>: A synchronization point between a pair of
-commands (A and B) assures that results of command A happens-before
-command B is launched (i.e. enters the ready state) .
-<br>
-<br>
-<strong>Synchronizes with</strong>: A relation between operations in two different
-units of execution that defines a memory order constraint in global
-memory (<em>global-synchronizes-with</em>) or local memory
-(<em>local-synchronizes-with</em>).
-<br>
-<br>
-<strong>Task Parallel Programming Model</strong>: A programming model in which
-computations are expressed in terms of multiple concurrent tasks
-executing in one or more <em>command-queues</em>. The concurrent tasks can be
-running different <em>kernels</em>.
-<br>
-<br>
-<strong>Thread-safe</strong>: An OpenCL API call is considered to be <em>thread-safe</em> if
-the internal state as managed by OpenCL remains consistent when called
-simultaneously by multiple <em>host</em> threads. OpenCL API calls that are
-<em>thread-safe</em> allow an application to call these functions in multiple
-<em>host</em> threads without having to implement mutual exclusion across these
-<em>host</em> threads i.e. they are also re-entrant-safe.
-<br>
-<br>
-<strong>Undefined</strong>: The behavior of an OpenCL API call, built-in function used
-inside a <em>kernel</em> or execution of a <em>kernel</em> that is explicitly not
-defined by OpenCL. A conforming implementation is not required to
-specify what occurs when an undefined construct is encountered in
-OpenCL.
-<br>
-<br>
-<strong>Unit of execution</strong>: a generic term for a process, OS managed thread
-running on the host (a host-thread), kernel-instance, host program,
-work-item or any other executable agent that advances the work
-associated with a program.
-<br>
-<br>
-<strong>Work-group</strong>: A collection of related <em>work-items</em> that execute on a
-single <em>compute unit</em>. The <em>work-items</em> in the group execute the same
-<em>kernel-instance</em> and share <em>local</em> <em>memory</em> and <em>work-group functions</em>.
-<br>
-<br>
-<strong>Work-group Barrier</strong>. See <em>Barrier</em>.
-<br>
-<br>
-<strong>Work-group Function</strong>: A function that carries out collective operations
-across all the work-items in a work-group. Available collective
-operations are a barrier, reduction, broadcast, prefix sum, and
-evaluation of a predicate. A work-group function must occur within a
-<em>converged control flow</em>; i.e. all work-items in the work-group must
-encounter precisely the same work-group function.
-<br>
-<br>
-<strong>Work-group Synchronization</strong>: Constraints on the order of execution for
-work-items in a single work-group.
-<br>
-<br>
-<strong>Work-pool</strong>: A logical pool associated with a device that holds commands
-and work-groups from kernel-instances that are ready to execute. OpenCL
-does not constrain the order that commands and work-groups are scheduled
-for execution from the work-pool; i.e. a programmer must assume that
-they could be interleaved. There is one work-pool per device used by
-all command-queues associated with that device. The work-pool may be
-implemented in any manner as long as it assures that work-groups placed
-in the pool will eventually execute.
-<br>
-<br>
-<strong>Work-item</strong>: One of a collection of parallel executions of a <em>kernel</em>
-invoked on a <em>device</em> by a <em>command</em>. A <em>work-item</em> is executed by one
-or more <em>processing elements</em> as part of a <em>work-group</em> executing on a
-<em>compute unit</em>. A <em>work-item</em> is distinguished from other work-items by
-its <em>global ID</em> or the combination of its <em>work-group</em> ID and its <em>local
-ID</em> within a <em>work-group</em>.</p></div>

-<div class="sectionbody">
-<div class="paragraph"><p><strong>OpenCL</strong> is an open industry standard for programming a heterogeneous
-collection of CPUs, GPUs and other discrete computing devices organized
-into a single platform. It is more than a language. OpenCL is a
-framework for parallel programming and includes a language, API,
-libraries and a runtime system to support software development. Using
-OpenCL, for example, a programmer can write general purpose programs
-that execute on GPUs without the need to map their algorithms onto a 3D
-graphics API such as OpenGL or DirectX.
-<br>
-<br>
-The target of OpenCL is expert programmers wanting to write portable yet
-efficient code. This includes library writers, middleware vendors, and
-performance oriented application programmers. Therefore OpenCL provides
-a low-level hardware abstraction plus a framework to support programming
-and many details of the underlying hardware are exposed.
-<br>
-<br>
-To describe the core ideas behind OpenCL, we will use a hierarchy of
-models:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Platform Model
-</p>

-<h3 id="_platform_model">3.1. Platform Model</h3>
-<div class="paragraph"><p>The Platform model for OpenCL is defined in <em>figure 3.1</em>. The model
-consists of a <strong>host</strong> connected to one or more <strong>OpenCL devices</strong>. An OpenCL
-device is divided into one or more <strong>compute units</strong> (CUs) which are further
-divided into one or more <strong>processing elements</strong> (PEs). Computations on a
-device occur within the processing elements.
-<br>
-<br>
-An OpenCL application is implemented as both host code and device kernel
-code.  The host code portion of an OpenCL application runs on a host
-processor according to the models native to the host platform. The
-OpenCL application host code submits the kernel code as commands from
-the host to OpenCL devices.  An OpenCL device executes the commands
-computation on the processing elements within the device. 
-<br>
-<br>
-An OpenCL device has considerable latitude on how computations are
-mapped onto the devices processing elements.  When processing elements
-within a compute unit execute the same sequence of statements across the
-processing elements, the control flow is said to be <em>converged.</em>
-Hardware optimized for executing a single stream of instructions over
-multiple processing elements is well suited to converged control
-flows. When the control flow varies from one processing element to
-another, it is said to be <em>diverged.</em> While a kernel always begins
-execution with a converged control flow, due to branching statements
-within a kernel, converged and diverged control flows may occur within a
-single kernel. This provides a great deal of flexibility in the
-algorithms that can be implemented with OpenCL.

-Programmers provide programs in the form of SPIR-V source binaries,
-OpenCL C or OpenCL C++ source strings or implementation-defined binary objects. The
-OpenCL platform provides a compiler to translate program input of either
-form into executable program objects. The device code compiler may be
-<em>online</em> or <em>offline</em>. An <em>online</em> <em>compiler</em> is available during host
-program execution using standard APIs. An <em>offline compiler</em> is
-invoked outside of host program control, using platform-specific
-methods. The OpenCL runtime allows developers to get a previously
-compiled device program executable and be able to load and execute a
-previously compiled device program executable.
-<br>
-<br>
-OpenCL defines two kinds of platform profiles: a <em>full profile</em> and a
-reduced-functionality <em>embedded profile</em>. A full profile platform must
-provide an online compiler for all its devices. An embedded platform
-may provide an online compiler, but is not required to do so.
-<br>
-<br>
-A device may expose special purpose functionality as a <em>built-in
-function</em>. The platform provides APIs for enumerating and invoking the
-built-in functions offered by a device, but otherwise does not define
-their construction or semantics. A <em>custom device</em> supports only
-built-in functions, and cannot be programmed via a kernel language.
-<br>
-<br>
-All device types support the OpenCL execution model, the OpenCL memory
-model, and the APIs used in OpenCL to manage devices.
-<br>
-<br>
-The platform model is an abstraction describing how OpenCL views the
-hardware. The relationship between the elements of the platform model
-and the hardware in a system may be a fixed property of a device or it
-may be a dynamic feature of a program dependent on how a compiler
-optimizes code to best utilize physical hardware.</p></div>

-<h3 id="_execution_model">3.2. Execution Model</h3>
-<div class="paragraph"><p>The OpenCL execution model is defined in terms of two distinct units of
-execution: <strong>kernels</strong> that execute on one or more OpenCL devices and a
-<strong>host program</strong> that executes on the host. With regard to OpenCL, the
-kernels are where the "work" associated with a computation occurs. This
-work occurs through <strong>work-items</strong> that execute in groups (<strong>work-groups</strong>).
-<br>
-<br>
-A kernel executes within a well-defined context managed by the host.
-The context defines the environment within which kernels execute. It
-includes the following resources:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Devices</strong>: One or
-more devices exposed by the OpenCL platform.
-</p>

-<strong>Memory
-Objects</strong>:Variables visible to the host and the OpenCL devices.
-Instances of kernels operate on these objects as they execute.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>The host program uses the OpenCL API to create and manage the context.
-Functions from the OpenCL API enable the host to interact with a device
-through a <em>command-queue</em>. Each command-queue is associated with a
-single device. The commands placed into the command-queue fall into
-one of three types:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Kernel-enqueue commands</strong>:
-Enqueue a kernel for execution on a device.
-</p>

-<strong>Memory commands</strong>:
-Transfer data between the host and device memory, between memory
-objects, or map and unmap memory objects from the host address space.

-</li>
-<li>
-<p>
-<strong>Synchronization
-commands</strong>: Explicit synchronization points that define order constraints
-between commands.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>In addition to commands submitted from the host command-queue, a kernel
-running on a device can enqueue commands to a device-side command queue.
-This results in <em>child kernels</em> enqueued by a kernel executing on a

-resides on the host or a device, each command passes through six states.</p></div>
-<div class="olist arabic"><ol class="arabic">
-<li>
-<p>
-<strong>Queued</strong>: The command is enqueued to a command-queue. A

-</p>
-</li>
-<li>
-<p>
-<strong>Submitted</strong>: The command is flushed from the command-queue and

-execution are met.
-</p>
-</li>
-<li>

-<strong>Ready</strong>: All prerequisites constraining execution of a command

-<strong>Ended</strong>: Execution of a command ends. When a Kernel-enqueue
-command ends, all of the work-groups associated with that command have

-<div class="paragraph"><p>Commands communicate their status through <em>Event objects</em>. Successful
-completion is indicated by setting the event status associated with a

-A command submitted to a device will not launch until prerequisites that
-constrain the order of commands have been resolved. These
-prerequisites have three sources:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-They may arise from
-commands submitted to a command-queue that constrain the order in which
-commands are launched. For example, commands that follow a command queue
-barrier will not launch until all commands prior to the barrier are
-complete.
-</p>
-</li>
-<li>
-<p>
-The second source of
-prerequisites is dependencies between commands expressed through events.
-A command may include an optional list of events. The command will wait
-and not launch until all the events in the list are in the state CL
-COMPLETE. By this mechanism, event objects define order constraints
-between commands and coordinate execution between the host and one or
-more devices.
-</p>
-</li>
-<li>
-<p>
-The third source of
-prerequisities can be the presence of non-trivial C initializers or C<span class="monospaced">
-constructors for program scope global variables. In this case, OpenCL
-C/C</span> compiler shall generate program initialization kernels that
-perform C initialization or C<span class="monospaced"> construction. These kernels must be
-executed by OpenCL runtime on a device before any kernel from the same
-program can be executed on the same device. The ND-range for any program
-initialization kernel is (1,1,1). When multiple programs are linked
-together, the order of execution of program initialization kernels
-that belong to different programs is undefined.
-<br>
-<br>
-Program clean up may result in the execution of one or more program
-clean up kernels by the OpenCL runtime. This is due to the presence of
-non-trivial C\</span> destructors for program scope variables. The ND-range
-for executing any program clean up kernel is (1,1,1). The order of
-execution of clean up kernels from different programs (that are linked
-together) is undefined.
-<br>
-<br>
-Note that C initializers, C<span class="monospaced"> constructors, or C</span> destructors for
-program scope variables cannot use pointers to coarse grain and fine
-grain SVM allocations.
-<br>
-<br>
-A command may be submitted to a device and yet have no visible side effects
-outside of waiting on and satisfying event dependences. Examples include
-markers, kernels executed over ranges of no work-items or copy
-operations with zero sizes. Such commands may pass directly from the
-<em>ready</em> state to the <em>ended</em> state.
-<br>
-<br>
-Command execution can be blocking or non-blocking. Consider a sequence
-of OpenCL commands. For blocking commands, the OpenCL API functions
-that enqueue commands don&#8217;t return until the command has completed.
-Alternatively, OpenCL functions that enqueue non-blocking commands
-return immediately and require that a programmer defines dependencies
-between enqueued commands to ensure that enqueued commands are not
-launched before needed resources are available. In both cases, the
-actual execution of the command may occur asynchronously with execution
-of the host program.
-<br>
-<br>
-Commands within a single command-queue execute relative to each other in
-one of two modes:
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>In-order Execution</strong>:
-Commands and any side effects associated with commands appear to the
-OpenCL application as if they execute in the same order they are
-enqueued to a command-queue.
-</p>
-</li>
-<li>
-<p>
-<strong>Out-of-order Execution</strong>:
-Commands execute in any order constrained only by explicit
-synchronization points (e.g. through command queue barriers) or explicit
-dependencies on events.
-<br>
-<br>
-Multiple command-queues can be present within a single context.
-Multiple command-queues execute commands independently. Event objects
-visible to the host program can be used to define synchronization points
-between commands in multiple command queues. If such synchronization
-points are established between commands in multiple command-queues, an
-implementation must assure that the command-queues progress concurrently
-and correctly account for the dependencies established by the
-synchronization points. For a detailed explanation of synchronization
-points, see section 3.2.4.
-<br>
-<br>
-The core of the OpenCL execution model is defined by how the kernels
-execute. When a kernel-enqueue command submits a kernel for execution,
-an index space is defined. The kernel, the argument values associated
-with the arguments to the kernel, and the parameters that define the
-index space define a <em>kernel-instance</em>. When a kernel-instance executes
-on a device, the kernel function executes for each point in the defined
-index space. Each of these executing kernel functions is called a
-<em>work-item</em>. The work-items associated with a given kernel-instance are
-managed by the device in groups called <em>work-groups</em>. These work-groups
-define a coarse grained decomposition of the Index space. Work-groups
-are further divided into <em>sub-groups</em>, which provide an additional level
-of control over execution.
-<br>
-<br>
-Work-items have a global ID based on their coordinates within the Index
-space. They can also be defined in terms of their work-group and the
-local ID within a work-group. The details of this mapping are described
-in the following section.

-<div class="sect3">
-<h4 id="_execution_model_mapping_work_items_onto_an_ndrange">3.2.1. Execution Model: Mapping work-items onto an NDRange</h4>
-<div class="paragraph"><p>The index space supported by OpenCL is called an NDRange. An NDRange is
-an N-dimensional index space, where N is one, two or three. The NDRange
-is decomposed into work-groups forming blocks that cover the Index
-space. An NDRange is defined by three integer arrays of length N:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-The extent of the index
-space (or global size) in each dimension.
-</p>
-</li>
-<li>
-<p>
-An offset index F
-indicating the initial value of the indices in each dimension (zero by
-default).
-</p>
-</li>
-<li>
-<p>
-The size of a work-group
-(local size) in each dimension.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>Each work-items global ID is an N-dimensional tuple. The global ID
-components are values in the range from F, to F plus the number of
-elements in that dimension minus one.
-<br>
-<br>
-If a kernel is created from OpenCL C 2.0 or SPIR-V, the size of work-groups
-in an NDRange (the local size) need not be the same for all work-groups.
-In this case, any single dimension for which the global size is not
-divisible by the local size will be partitioned into two regions. One
-region will have work-groups that have the same number of work items as
-was specified for that dimension by the programmer (the local size). The
-other region will have work-groups with less than the number of work
-items specified by the local size parameter in that dimension (the
-<em>remainder work-groups</em>). Work-group sizes could be non-uniform in
-multiple dimensions, potentially producing work-groups of up to 4
-different sizes in a 2D range and 8 different sizes in a 3D range.
-<br>
-<br>
-Each work-item is assigned to a work-group and given a local ID to
-represent its position within the work-group. A work-item&#8217;s local ID is
-an N-dimensional tuple with components in the range from zero to the
-size of the work-group in that dimension minus one.
-<br>
-<br>
-Work-groups are assigned IDs similarly. The number of work-groups in
-each dimension is not directly defined but is inferred from the local
-and global NDRanges provided when a kernel-instance is enqueued. A
-work-group&#8217;s ID is an N-dimensional tuple with components in the range 0
-to the ceiling of the global size in that dimension divided by the local
-size in the same dimension. As a result, the combination of a
-work-group ID and the local-ID within a work-group uniquely defines a
-work-item. Each work-item is identifiable in two ways; in terms of a
-global index, and in terms of a work-group index plus a local index
-within a work group.
-<br>
-<br>
-For example, consider the 2-dimensional index space in figure 3-3. We
-input the index space for the work-items (G<sub>x</sub>, G<sub>y</sub>), the size of each
-work-group (S<sub>x</sub>, S<sub>y</sub>) and the global ID offset (F<sub>x</sub>, F<sub>y</sub>). The
-global indices define an G<sub>x</sub>by G<sub>y</sub> index space where the total number
-of work-items is the product of G<sub>x</sub> and G<sub>y</sub>. The local indices define
-an S<sub>x</sub> by S<sub>y</sub> index space where the number of work-items in a single
-work-group is the product of S<sub>x</sub> and S<sub>y</sub>. Given the size of each
-work-group and the total number of work-items we can compute the number
-of work-groups. A 2-dimensional index space is used to uniquely identify
-a work-group. Each work-item is identified by its global ID (<em>g</em><sub>x</sub>,
-<em>g</em><sub>y</sub>) or by the combination of the work-group ID (<em>w</em><sub>x</sub>, <em>w</em><sub>y</sub>), the
-size of each work-group (S<sub>x</sub>,S<sub>y</sub>) and the local ID (s<sub>x</sub>, s<sub>y</sub>) inside
-the work-group such that

-<br>
-<br>
-The number of work-groups can be computed as:
-<br></p></div>
-<div class="paragraph"><p>&#160; &#160; &#160; &#160; (W<sub>x</sub>, W<sub>y</sub>) = (ceil(G<sub>x</sub> / S<sub>x</sub>),ceil( G<sub>y</sub> / S<sub>y</sub>))

-Within a work-group work-items may be divided into sub-groups. The

-work-groups, each sub-group is 1-dimensional and any given work-item may
-query which sub-group it is a member of.
-<br>
-<br>
-Work items are mapped into sub-groups through a combination of
-compile-time decisions and the parameters of the dispatch. The mapping
-to sub-groups is invariant for the duration of a kernels execution,
-across dispatches of a given kernel with the same work-group dimensions,

-(excluding the trailing edge work-groups in the presence of non-uniform

-be the same size, apart from the sub-group with the maximum index which
-may be smaller if the size of the work-group is not evenly divisible by

-<h4 id="_execution_model_execution_of_kernel_instances">3.2.2. Execution Model: Execution of kernel-instances</h4>
-<div class="paragraph"><p>The work carried out by an OpenCL program occurs through the execution
-of kernel-instances on compute devices. To understand the details of
-OpenCLs execution model, we need to consider how a kernel object moves
-from the kernel-enqueue command, into a command-queue, executes on a
-device, and completes.
-<br>
-<br>
-A kernel-object is defined from a function within the program object and
-a collection of arguments connecting the kernel to a set of argument
-values. The host program enqueues a kernel-object to the command queue
-along with the NDRange, and the work-group decomposition. These define
-a <em>kernel-instance</em>. In addition, an optional set of events may be
-defined when the kernel is enqueued. The events associated with a
-particular kernel-instance are used to constrain when the
-kernel-instance is launched with respect to other commands in the queue
-or to commands in other queues within the same context.
-<br>
-<br>
-A kernel-instance is submitted to a device. For an in-order command
-queue, the kernel instances appear to launch and then execute in that
-same order; where we use the term appear to emphasize that when there
-are no dependencies between commands and hence differences in the order
-that commands execute cannot be observed in a program, an implementation
-can reorder commands even in an in-order command queue. For an out of
-order command-queue, kernel-instances wait to be launched until:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-Synchronization commands
-enqueued prior to the kernel-instance are satisfied.
-</p>
-</li>
-<li>
-<p>
-Each of the events in an
-optional event list defined when the kernel-instance was enqueued are
-set to CL_COMPLETE.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>Once these conditions are met, the kernel-instance is launched and the
-work-groups associated with the kernel-instance are placed into a pool
-of ready to execute work-groups. This pool is called a <em>work-pool</em>.
-The work-pool may be implemented in any manner as long as it assures
-that work-groups placed in the pool will eventually execute. The
-device schedules work-groups from the work-pool for execution on the
-compute units of the device. The kernel-enqueue command is complete when
-all work-groups associated with the kernel-instance end their execution,
-updates to global memory associated with a command are visible globally,
-and the device signals successful completion by setting the event
-associated with the kernel-enqueue command to CL_COMPLETE.
-<br>
-<br>
-While a command-queue is associated with only one device, a single
-device may be associated with multiple command-queues all feeding into
-the single work-pool. A device may also be associated with command
-queues associated with different contexts within the same platform,
-again all feeding into the single work-pool. The device will pull
-work-groups from the work-pool and execute them on one or several
-compute units in any order; possibly interleaving execution of
-work-groups from multiple commands. A conforming implementation may
-choose to serialize the work-groups so a correct algorithm cannot assume
-that work-groups will execute in parallel. There is no safe and
-portable way to synchronize across the independent execution of
-work-groups since once in the work-pool, they can execute in any order.
-<br>
-<br>
-The work-items within a single sub-group execute concurrently but not
-necessarily in parallel (i.e. they are not guaranteed to make
-independent forward progress). Therefore, only high-level
-synchronization constructs (e.g. sub-group functions such as barriers)
-that apply to all the work-items in a sub-group are well defined and
-included in OpenCL.
-<br>
-<br>
-Sub-groups execute concurrently within a given work-group and with
-appropriate device support (<em>see Section__4.2</em>) may make independent
-forward progress with respect to each other, with respect to host
-threads and with respect to any entities external to the OpenCL system
-but running on an OpenCL device, even in the absence of work-group
-barrier operations. In this situation, sub-groups are able to internally
-synchronize using barrier operations without synchronizing with each
-other and may perform operations that rely on runtime dependencies on
-operations other sub-groups perform.
-<br>
-<br>
-The work-items within a single work-group execute concurrently but are
-only guaranteed to make independent progress in the presence of
-sub-groups and device support. In the absence of this capability, only
-high-level synchronization constructs (e.g. work-group functions such as
-barriers) that apply to all the work-items in a work-group are well
-defined and included in OpenCL for synchronization within the
-work-group.
-<br>
-<br>
-In the absence of synchronization functions (e.g. a barrier), work-items
-within a sub-group may be serialized. In the presence of sub -group
-functions, work-items within a sub -group may be serialized before any
-given sub -group function, between dynamically encountered pairs of sub
--group functions and between a work-group function and the end of the
-kernel.
-<br>
-<br>
-In the absence of independent forward progress of constituent
-sub-groups, work-items within a work-group may be serialized before,
-after or between work-group synchronization functions.</p></div>

-<h4 id="_execution_model_device_side_enqueue">3.2.3. Execution Model: Device-side enqueue</h4>
-<div class="paragraph"><p>Algorithms may need to generate additional work as they execute. In
-many cases, this additional work cannot be determined statically; so the
-work associated with a kernel only emerges at runtime as the
-kernel-instance executes. This capability could be implemented in logic
-running within the host program, but involvement of the host may add
-significant overhead and/or complexity to the application control
-flow. A more efficient approach would be to nest kernel-enqueue
-commands from inside other kernels. This <strong>nested parallelism</strong> can be
-realized by supporting the enqueuing of kernels on a device without
-direct involvement by the host program; so-called <strong>device-side
-enqueue</strong>.
-<br>
-<br>
-Device-side kernel-enqueue commands are similar to host-side
-kernel-enqueue commands. The kernel executing on a device (the <strong>parent
-kernel</strong>) enqueues a kernel-instance (the <strong>child kernel</strong>) to a
-device-side command queue. This is an out-of-order command-queue and
-follows the same behavior as the out-of-order command-queues exposed to
-the host program. Commands enqueued to a device side command-queue
-generate and use events to enforce order constraints just as for the
-command-queue on the host. These events, however, are only visible to
-the parent kernel running on the device. When these prerequisite
-events take on the value CL_COMPLETE, the work-groups associated with
-the child kernel are launched into the devices work pool. The device
-then schedules them for execution on the compute units of the device.
-Child and parent kernels execute asynchronously. However, a parent will
-not indicate that it is complete by setting its event to CL_COMPLETE
-until all child kernels have ended execution and have signaled
-completion by setting any associated events to the value CL_COMPLETE.
-Should any child kernel complete with an event status set to a negative
-value (i.e. abnormally terminate), the parent kernel will abnormally
-terminate and propagate the childs negative event value as the value of
-the parents event. If there are multiple children that have an event
-status set to a negative value, the selection of which childs negative
-event value is propagated is implementation-defined.</p></div>

-<div class="paragraph"><p>Synchronization across all work-items within a single work-group is

-Available collective operations are: barrier, reduction, broadcast,

-iterations. All the work-items of a work-group must execute the

-Work-group functions that apply between work-groups are not provided in

-<br>
-<br>
-Command synchronization is defined in terms of distinct <strong>synchronization
-points</strong>. The synchronization points occur between commands in host
-command-queues and between commands in device-side command-queues. The
-synchronization points defined in OpenCL include:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Launching a command:</strong> A
-kernel-instance is launched onto a device after all events that kernel
-is waiting-on have been set to CL_COMPLETE.
-</p>
-</li>
-<li>
-<p>
-<strong>Ending a command:</strong> Child
-kernels may be enqueued such that they wait for the parent kernel to
-reach the <em>end</em> state before they can be launched. In this case, the
-ending of the parent command defines a synchronization point.
-</p>
-</li>
-<li>
-<p>
-<strong>Completion of a command:</strong>
-A kernel-instance is complete after all of the work-groups in the kernel
-and all of its child kernels have completed. This is signaled to the
-host, a parent kernel or other kernels within command queues by setting
-the value of the event associated with a kernel to CL_COMPLETE.
-</p>
-</li>
-<li>
-<p>
-<strong>Blocking Commands:</strong> A

-execution that calls the blocking API function and the enqueued command
-reaching the complete state.
-</p>
-</li>
-<li>
-<p>
-<strong>Command-queue barrier:</strong>
-The command-queue barrier ensures that all previously enqueued commands
-have completed before subsequently enqueued commands can be launched.
-</p>
-</li>
-<li>
-<p>
-<strong>clFinish:</strong> This function
-blocks until all previously enqueued commands in the command queue have
-completed after which clFinish defines a synchronization point and the
-clFinish function returns.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>A synchronization point between a pair of commands (A and B) assures
-that results of command A happens-before command B is launched. This
-requires that any updates to memory from command A complete and are made
-available to other commands before the synchronization point completes.
-Likewise, this requires that command B waits until after the
-synchronization point before loading values from global memory. The
-concept of a synchronization point works in a similar fashion for
-commands such as a barrier that apply to two sets of commands. All the
-commands prior to the barrier must complete and make their results
-available to following commands. Furthermore, any commands following
-the barrier must wait for the commands prior to the barrier before

-<br>
-<br>
-These <em>happens-before</em> relationships are a fundamental part of the

-<div class="paragraph"><p>The OpenCL memory model describes the structure, contents, and behavior
-of the memory exposed by an OpenCL platform as an OpenCL program runs.
-The model allows a programmer to reason about values in memory as the
-host program and multiple kernel-instances execute.
-<br>
-<br>
-An OpenCL program defines a context that includes a host, one or more
-devices, command-queues, and memory exposed within the context.
-Consider the units of execution involved with such a program. The host
-program runs as one or more host threads managed by the operating system
-running on the host (the details of which are defined outside of
-OpenCL). There may be multiple devices in a single context which all
-have access to memory objects defined by OpenCL. On a single device,
-multiple work-groups may execute in parallel with potentially
-overlapping updates to memory. Finally, within a single work-group,
-multiple work-items concurrently execute, once again with potentially
-overlapping updates to memory.
-<br>
-<br>
-The memory model must precisely define how the values in memory as seen
-from each of these units of execution interact so a programmer can
-reason about the correctness of OpenCL programs. We define the memory
-model in four parts.</p></div>

-Memory objects: The
-objects defined by the OpenCL API and their management by the host and

-Shared Virtual Memory: A
-virtual address space exposed to both the host and the devices within a
-context.

-<div class="paragraph"><p>Memory in OpenCL is divided into two parts.</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Host Memory:</strong> The memory
-directly available to the host. The detailed behavior of host memory is
-defined outside of OpenCL. Memory objects move between the Host and the
-devices through functions within the OpenCL API or through a shared
-virtual memory interface.
-</p>
-</li>
-<li>
-<p>
-<strong>Device Memory:</strong> Memory
-directly available to kernels executing on OpenCL devices.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>Device memory consists of four named address spaces or <em>memory regions</em>:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Global Memory:</strong> This
-memory region permits read/write access to all work-items in all
-work-groups running on any device within a context. Work-items can read
-from or write to any element of a memory object. Reads and writes to
-global memory may be cached depending on the capabilities of the device.
-</p>
-</li>
-<li>
-<p>
-<strong>Constant Memory</strong>: A
-region of global memory that remains constant during the execution of a
-kernel-instance. The host allocates and initializes memory objects
-placed into constant memory.
-</p>
-</li>
-<li>
-<p>
-<strong>Local Memory</strong>: A memory
-region local to a work-group. This memory region can be used to allocate
-variables that are shared by all work-items in that work-group.
-</p>
-</li>
-<li>
-<p>
-<strong>Private Memory</strong>: A region
-of memory private to a work-item. Variables defined in one work-items
-private memory are not visible to another work-item.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>The memory regions and their relationship to the OpenCL Platform model
-are summarized in figure 3-4. Local and private memories are always
-associated with a particular device. The global and constant memories,
-however, are shared between all devices within a given context. An
-OpenCL device may include a cache to support efficient access to these
-shared memories
-<br>
-<br>
-To understand memory in OpenCL, it is important to appreciate the
-relationships between these named address spaces.   The four named
-address spaces available to a device are disjoint meaning they do not
-overlap.   This is a logical relationship, however, and an
-implementation may choose to let these disjoint named address spaces
-share physical memory.
-<br>
-<br>
-Programmers often need functions callable from kernels where the
-pointers manipulated by those functions can point to multiple named
-address spaces. This saves a programmer from the error-prone and
-wasteful practice of creating multiple copies of functions; one for each
-named address space. Therefore the global, local and private address
-spaces belong to a single <em>generic address space</em>. This is closely
-modeled after the concept of a generic address space used in the
-embedded C standard (ISO/IEC 9899:1999). Since they all belong to a
-single generic address space, the following properties are supported for
-pointers to named address spaces in device memory:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-A pointer to the generic
-address space can be cast to a pointer to a global, local or private
-address space
-</p>
-</li>
-<li>
-<p>
-A pointer to a global,
-local or private address space can be cast to a pointer to the generic
-address space.
-</p>
-</li>
-<li>
-<p>
-A pointer to a global,
-local or private address space can be implicitly converted to a pointer
-to the generic address space, but the converse is not allowed.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>The constant address space is disjoint from the generic address space.
-<br>
-<br>
-The addresses of memory associated with memory objects in Global memory
-are not preserved between kernel instances, between a device and the
-host, and between devices. In this regard global memory acts as a global
-pool of memory objects rather than an address space. This restriction is
-relaxed when shared virtual memory (SVM) is used.
-<br>
-<br>
-SVM causes addresses to be meaningful between the host and all of the
-devices within a context hence supporting the use of pointer based data
-structures in OpenCL kernels. It logically extends a portion of the
-global memory into the host address space giving work-items access to
-the host address space. On platforms with hardware support for a shared
-address space between the host and one or more devices, SVM may also
-provide a more efficient way to share data between devices and the host.
-Details about SVM are presented in section 3.3.3.</p></div>

-<h4 id="_memory_model_memory_objects">3.3.2. Memory Model: Memory Objects</h4>
-<div class="paragraph"><p>The contents of global memory are <em>memory objects</em>. A memory object is
-a handle to a reference counted region of global memory. Memory objects
-use the OpenCL type <em>cl_mem</em> and fall into three distinct classes.</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>Buffer</strong>: A memory object
-stored as a block of contiguous memory and used as a general purpose
-object to hold data used in an OpenCL program. The types of the values
-within a buffer may be any of the built in types (such as int, float),
-vector types, or user-defined structures. The buffer can be
-manipulated through pointers much as one would with any block of memory
-in C.
-</p>
-</li>
-<li>
-<p>
-<strong>Image</strong>: An image memory
-object holds one, two or three dimensional images. The formats are
-based on the standard image formats used in graphics applications. An
-image is an opaque data structure managed by functions defined in the
-OpenCL API. To optimize the manipulation of images stored in the
-texture memories found in many GPUs, OpenCL kernels have traditionally
-been disallowed from both reading and writing a single image. In OpenCL
-2.0, however, we have relaxed this restriction by providing
-synchronization and fence operations that let programmers properly
-synchronize their code to safely allow a kernel to read and write a
-single image.
-</p>
-</li>
-<li>
-<p>
-<strong>Pipe</strong>: The <em>pipe</em> memory
-object conceptually is an ordered sequence of data items. A pipe has
-two endpoints: a write endpoint into which data items are inserted, and
-a read endpoint from which data items are removed. At any one time,
-only one kernel instance may write into a pipe, and only one kernel
-instance may read from a pipe. To support the producer consumer design
-pattern, one kernel instance connects to the write endpoint (the
-producer) while another kernel instance connects to the reading endpoint
-(the consumer).
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>Memory objects are allocated by host APIs. The host program can provide
-the runtime with a pointer to a block of continuous memory to hold the
-memory object when the object is created (CL_MEM_USE_HOST_PTR).
-Alternatively, the physical memory can be managed by the OpenCL runtime
-and not be directly accessible to the host program.
-<br>
-<br>
-Allocation and access to memory objects within the different memory
-regions varies between the host and work-items running on a device.
-This is summarized in table 3.1 which__describes whether the kernel or
-the host can allocate from a memory region, the type of allocation
-(static at compile time vs. dynamic at runtime) and the type of access
-allowed (i.e. whether the kernel or the host can read and/or write to a
-memory region).</p></div>

-<div class="ulist"><ul>
-<li>
-<p>

-enqueued to an OpenCL command queue.
-</p>
-</li>
-<li>
-<p>
-<strong>Map/Unmap commands</strong>: Data
-from the memory object is mapped into a contiguous block of memory
-accessed through a host accessible pointer. The host program enqueues a
-<em>map</em> command on block of a memory object before it can be safely
-manipulated by the host program. When the host program is finished
-working with the block of memory, the host program enqueues an <em>unmap</em>
-command to allow a kernel-instance to safely read and/or write the
-buffer.**
-</p>
-</li>
-<li>
-<p>
-<strong>Copy commands:</strong> The data
-associated with a memory object is copied between two buffers, each of
-which may reside either on the host or on the device.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>In both cases, the commands to transfer data between devices and the

-call for a blocking memory transfer returns once the associated memory
-resources on the host can be safely reused. For a non-blocking memory
-transfer, the OpenCL function call returns as soon as the command is
-enqueued.
-<br>

-Memory objects are bound to a context and hence can appear in multiple
-kernel-instances running on more than one physical device. The OpenCL
-platform must support a large range of hardware platforms including
-systems that do not support a single shared address space in hardware;
-hence the ways memory objects can be shared between kernel-instances is
-restricted. The basic principle is that multiple read operations on
-memory objects from multiple kernel-instances that overlap in time are
-allowed, but mixing overlapping reads and writes into the same memory
-objects from different kernel instances is only allowed when fine
-grained synchronization is used with shared virtual memory (see section
-3.3.3).
-<br>
-<br>
-When global memory is manipulated by multiple kernel-instances running
-on multiple devices, the OpenCL runtime system must manage the
-association of memory objects with a given device. In most cases the
-OpenCL runtime will implicitly associate a memory object with a device.
-A kernel instance is naturally associated with the command queue to
-which the kernel was submitted. Since a command-queue can only access a
-single device, the queue uniquely defines which device is involved with
-any given kernel-instance; hence defining a clear association between
-memory objects, kernel-instances and devices. Programmers may

-<div class="paragraph"><p>The OpenCL memory model tells programmers what they can expect from an
-OpenCL implementation; which memory operations are guaranteed to happen
-in which order and which memory values each read operation will return.
-The memory model tells compiler writers which restrictions they must
-follow when implementing compiler optimizations; which variables they
-can cache in registers and when they can move reads or writes around a
-barrier or atomic operation. The memory model also tells hardware
-designers about limitations on hardware optimizations; for example, when
-they must flush or invalidate hardware caches.
-<br>
-<br>
-The memory consistency model in OpenCL is based on the memory model from
-the ISO C11 programming language. To help make the presentation more
-precise and self-contained, we include modified paragraphs taken
-verbatim from the ISO C11 international standard. When a paragraph is
-taken or modified from the C11 standard, it is identified as such along
-with its original location in the C11 standard.
-<br>
-<br>
-For programmers, the most intuitive model is the <em>sequential
-consistency</em> memory model. Sequential consistency interleaves the steps
-executed by each of the units of execution. Each access to a memory
-location sees the last assignment to that location in that
-interleaving. While sequential consistency is relatively
-straightforward for a programmer to reason about, implementing
-sequential consistency is expensive. Therefore, OpenCL implements a
-relaxed memory consistency model; i.e. it is possible to write programs
-where the loads from memory violate sequential consistency. Fortunately,
-if a program does not contain any races and if the program only uses
-atomic operations that utilize the sequentially consistent memory order
-(the default memory ordering for OpenCL), OpenCL programs appear to
-execute with sequential consistency.
-<br>
-<br>
-Programmers can to some degree control how the memory model is relaxed by choosing the memory order for synchronization operations. The precise semantics of synchronization and the memory orders are formally defined in section 3.3.6. Here, we give a high level description of how these memory orders apply to atomic operations on atomic objects shared between units of execution. OpenCL memory_order choices are based on those from the ANSI C11 standard memory model. They are specified in certain OpenCL functions through the following enumeration constants:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-<strong>memory_order_relaxed</strong>:
-implies no order constraints. This memory order can be used safely to
-increment counters that are concurrently incremented, but it doesnt
-guarantee anything about the ordering with respect to operations to
-other memory locations. It can also be used, for example, to do ticket
-allocation and by expert programmers implementing lock-free algorithms.
-</p>
-</li>
-<li>
-<p>
-<strong>memory_order_acquire</strong>: A
-synchronization operation (fence or atomic) that has acquire semantics
-"acquires" side-effects from a release operation that synchronises with
-it: if an acquire synchronises with a release, the acquiring unit of
-execution will see all side-effects preceding that release (and possibly
-subsequent side-effects.) As part of carefully-designed protocols,
-programmers can use an "acquire" to safely observe the work of another
-unit of execution.

-<strong>memory_order_release</strong>: A

-<strong>memory_scope_all_svm_devices</strong>: memory-ordering constraints apply to

-buffer that does not have the CL_MEM_SVM_ATOMICS flag set will commit to
-at least <strong>memory_scope_device</strong> visibility, with full synchronization of
-the buffer at a queue synchronization point (e.g. an OpenCL event).
-<br>
-<br>
-These memory scopes define a hierarchy of visibilities when analyzing
-the ordering constraints of memory operations. For example if a
-programmer knows that a sequence of memory operations will only be
-associated with a collection of work-items from a single work-group (and
-hence will run on a single device), the implementation is spared the
-overhead of managing the memory orders across other devices within the
-same context. This can substantially reduce overhead in a program. All
-memory scopes are valid when used on global memory or local memory. For
-local memory, all visibility is constrained to within a given work-group
-and scopes wider than <strong>memory_scope_work_group</strong> carry no additional
-meaning.
-<br>
-<br>
-In the following subsections (leading up to section 3.4), we will
-explain the synchronization constructs and detailed rules needed to use
-OpenCLs relaxed memory models. It is important to appreciate,
-however, that many programs do not benefit from relaxed memory models.
-Even expert programmers have a difficult time using atomics and fences
-to write correct programs with relaxed memory models. A large number of
-OpenCL programs can be written using a simplified memory model. This is
-accomplished by following these guidelines.
-</p>
-</li>
-<li>
-<p>
-Write programs that manage
-safe sharing of global memory objects through the synchronization points
-defined by the command queues.

-<p>
-Restrict low level
-synchronization inside work-groups to the work-group functions such as
-barrier.
-</p>
-</li>
-<li>
-<p>
-If you want sequential
-consistency behavior with system allocations or fine-grain SVM buffers
-with atomics support, use only memory_order_seq_cst operations with the

-If you want sequential

-<h4 id="_memory_model_overview_of_atomic_and_fence_operations">3.3.5. Memory Model: Overview of atomic and fence operations</h4>
-<div class="paragraph"><p>The OpenCL 2.0 specification defines a number of <em>synchronization
-operations</em> that are used to define memory order constraints in a
-program. They play a special role in controlling how memory operations
-in one unit of execution (such as work-items or, when using SVM a host
-thread) are made visible to another. There are two types of
-synchronization operations in OpenCL; <em>atomic operations</em> and <em>fences</em>.
-<br>
-<br>
-Atomic operations are indivisible. They either occur completely or not
-at all. These operations are used to order memory operations between
-units of execution and hence they are parameterized with the
-memory_order and memory_scope parameters defined by the OpenCL memory
-consistency model. The atomic operations for OpenCL kernel languages
-are similar to the corresponding operations defined
-by the C11 standard.
-<br>
-<br>
-The OpenCL 2.0 atomic operations apply to variables of an atomic type (a
-subset of those in the C11 standard) including atomic versions of the
-int, uint, long, ulong, float, double, half, intptr_t, uintptr_t,
-size_t, and ptrdiff_t types. However, support for some of these atomic
-types depends on support for the corresponding regular types.
-<br>
-<br>
-An atomic operation on one or more memory locations is either an acquire
-operation, a release operation, or both an acquire and release
-operation. An atomic operation without an associated memory location is
-a fence and can be either an acquire fence, a release fence, or both an
-acquire and release fence. In addition, there are relaxed atomic
-operations, which do not have synchronization properties, and atomic
-read-modify-write operations, which have special characteristics. [C11
-standard, Section 5.1.2.4, paragraph 5, modified]
-<br>
-<br>
-The orders memory_order_acquire (used for reads), memory_order_release
-(used for writes), and memory_order_acq_rel (used for read-modify-write
-operations) are used for simple communication between units of execution
-using shared variables. Informally, executing a memory_order_release on
-an atomic object A makes all previous side effects visible to any unit
-of execution that later executes a memory_order_acquire on A. The orders
-memory_order_acquire, memory_order_release, and memory_order_acq_rel do
-not provide sequential consistency for race-free programs because they
-will not ensure that atomic stores followed by atomic loads become
-visible to other threads in that order.
-<br>
-<br>
-The fence operation is atomic_work_item_fence, which includes a
-memory_order argument as well as the memory_scope and cl_mem_fence_flags
-arguments. Depending on the memory_order argument, this operation:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-has no effects, if
-memory_order_relaxed;
-</p>
-</li>
-<li>
-<p>
-is an acquire fence, if
-memory_order_acquire;
-</p>
-</li>
-<li>
-<p>
-is a release fence, if
-memory_order_release;
-</p>
-</li>
-<li>
-<p>
-is both an acquire fence
-and a release fence, if memory_order_acq_rel;
-</p>
-</li>
-<li>
-<p>
-is a
-sequentially-consistent fence with both acquire and release semantics,
-if memory_order_seq_cst.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>If specified, the cl_mem_fence_flags argument must be
-CLK_IMAGE_MEM_FENCE, CLK_GLOBAL_MEM_FENCE, CLK_LOCAL_MEM_FENCE, or
-CLK_GLOBAL_MEM_FENCE | CLK_LOCAL_MEM_FENCE.
-<br>
-<br>
-The atomic_work_item_fence(CLK_IMAGE_MEM_FENCE) built-in function must
-be
-<br>
-<br>
-used to make sure that sampler-less writes are visible to later reads by
-the same work-item. Without use of the atomic_work_item_fence function,
-write-read coherence on image objects is not guaranteed: if a work-item
-reads from an image to which it has previously written without an
-intervening atomic_work_item_fence, it is not guaranteed that those
-previous writes are visible to the work-item.
-<br>
-<br>
-The synchronization operations in OpenCL can be parameterized by a
-memory_scope. Memory scopes control the extent that an atomic operation
-or fence is visible with respect to the memory model. These memory
-scopes may be used when performing atomic operations and fences on
-global memory and local memory. When used on global memory visibility
-is bounded by the capabilities of that memory. When used on a
-fine-grained non-atomic SVM buffer, a coarse-grained SVM buffer, or a
-non-SVM buffer, operations parameterized with
-memory_scope_all_svm_devices will behave as if they were parameterized
-with memory_scope_device. When used on local memory, visibility is
-bounded by the work-group and, as a result, memory_scope with wider
-visibility than memory_scope_work_group will be reduced to
-memory_scope_work_group.</p></div>

-<h4 id="_memory_model_memory_ordering_rules">3.3.6. Memory Model: Memory Ordering Rules</h4>
-<div class="paragraph"><p>Fundamentally, the issue in a memory model is to understand the
-orderings in time of modifications to objects in memory. Modifying an
-object or calling a function that modifies an object are side effects,
-i.e. changes in the state of the execution environment. Evaluation of an
-expression in general includes both value computations and initiation of
-side effects. Value computation for an lvalue expression includes
-determining the identity of the designated object. [C11 standard,
-Section 5.1.2.3, paragraph 2, modified]
-<br>
-<br>
-We assume that the OpenCL kernel language and host
-programming languages have a sequenced-before relation between the
-evaluations executed by a single unit of execution. This
-sequenced-before relation is an asymmetric, transitive, pair-wise
-relation between those evaluations, which induces a partial order among
-them. Given any two evaluations <strong>A</strong> and <strong>B</strong>, if <strong>A</strong> is sequenced-before
-<strong>B</strong>, then the execution of <strong>A</strong> shall precede the execution of <strong>B</strong>.
-(Conversely, if <strong>A</strong> is sequenced-before <strong>B</strong>, then <strong>B</strong> is sequenced-after
-<strong>A</strong>.) If <strong>A</strong> is not sequenced-before or sequenced-after <strong>B</strong>, then <strong>A</strong>
-and <strong>B</strong> are unsequenced. Evaluations <strong>A</strong> and <strong>B</strong> are indeterminately
-sequenced when <strong>A</strong> is either sequenced-before or sequenced-after <strong>B</strong>,
-but it is unspecified which. [C11 standard, Section 5.1.2.3, paragraph
-3, modified]
-<br>
-<br>
-NOTE: sequenced-before is a partial order of the operations executed by
-a single unit of execution (e.g. a host thread or work-item). It
-generally corresponds to the source program order of those operations,
-and is partial because of the undefined argument evaluation order of
-OpenCLs kernel C language.
-<br>
-<br>
-In an OpenCL kernel language, the value of an object
-visible to a work-item W at a particular point is the initial value of
-the object, a value stored in the object by W, or a value stored in the
-object by another work-item or host thread, according to the rules
-below. Depending on details of the host programming language, the value
-of an object visible to a host thread may also be the value stored in
-that object by another work-item or host thread. [C11 standard, Section
-5.1.2.4, paragraph 2, modified]
-<br>
-<br>
-Two expression evaluations conflict if one of them modifies a memory
-location and the other one reads or modifies the same memory location. [C11 standard, Section 5.1.2.4, paragraph 4]
-<br>
-<br>
-All modifications to a particular atomic object <strong>M</strong> occur in some
-particular total order, called the modification order of <strong>M</strong>. If <strong>A</strong> and
-<strong>B</strong> are modifications of an atomic object <strong>M</strong>, and <strong>A</strong> happens-before
-<strong>B</strong>, then <strong>A</strong> shall precede <strong>B</strong> in the modification order of <strong>M</strong>, which
-is defined below. Note that the modification order of an atomic object
-<strong>M</strong> is independent of whether <strong>M</strong> is in local or global memory. [C11
-standard, Section 5.1.2.4, paragraph 7, modified]
-<br>
-<br>
-A release sequence begins with a release operation <strong>A</strong> on an atomic
-object <strong>M</strong> and is the maximal contiguous sub-sequence of side effects
-in the modification order of <strong>M</strong>, where the first operation is <strong>A</strong> and
-every subsequent operation either is performed by the same work-item or
-host thread that performed the release or is an atomic
-read-modify-write operation. [C11 standard, Section 5.1.2.4, paragraph
-10, modified]
-<br>
-<br>
-OpenCLs local and global memories are disjoint. Kernels may access both
-kinds of memory while host threads may only access global memory.
-Furthermore, the <em>flags</em> argument of OpenCLs work_group_barrier
-function specifies which memory operations the function will make
-visible: these memory operations can be, for example, just the ones to
-local memory, or the ones to global memory, or both. Since the
-visibility of memory operations can be specified for local memory
-separately from global memory, we define two related but independent
-relations, <em>global-synchronizes-with</em> and <em>local-synchronizes-with</em>.
-Certain operations on global memory may global-synchronize-with other
-operations performed by another work-item or host thread. An example is
-a release atomic operation in one work- item that
-global-synchronizes-with an acquire atomic operation in a second
-work-item. Similarly, certain atomic operations on local objects in
-kernels can local-synchronize- with other atomic operations on those
-local objects. [C11 standard, Section 5.1.2.4, paragraph 11, modified]

-types of command queues and associated API functions in OpenCL 2.0;
-<em>host command-queues</em> and <em>device command-queues</em>. The interaction of
-these command queues with the memory model are for the most part
-equivalent. In a few cases, the rules only applies to the host
-command-queue. We will indicate these special cases by specifically
-denoting the host command-queue in the memory ordering rule. SVM memory

-synchronizing host commands.</p></div>

-<div class="paragraph"><p>Memory ordering rules in this section apply to all memory objects

-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>In the remainder of this section, we assume that each command <strong>C</strong>
-enqueued onto a command-queue has an associated event object <strong>E</strong> that
-signals its execution status, regardless of whether <strong>E*was returned to
-the unit of execution that enqueued *C</strong>. We also distinguish between
-the API function call that enqueues a command <strong>C</strong> and creates an event
-<strong>E</strong>, the execution of <strong>C</strong>, and the completion of <strong>C</strong>(which marks the
-event <strong>E</strong> as complete).</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>The ordering and synchronization rules for API commands are defined as
-following:</p></div>
-<div class="olist arabic"><ol class="arabic">
-<li>
-<p>
-If an API function call <strong>X</strong> enqueues a command <strong>C</strong>, then <strong>X</strong>
-global-synchronizes-with <strong>C</strong>. For example, a host API function to
-enqueue a kernel global-synchronizes-with the start of that
-kernel-instances execution, so that memory updates sequenced-before the
-enqueue kernel function call will global-happen-before any kernel reads
-or writes to those same memory locations. For a device-side enqueue,
-global memory updates sequenced before <strong>X</strong> happens-before <strong>C</strong> reads or
-writes to those memory locations only in the case of fine-grained SVM.
-</p>
-</li>
-<li>
-<p>
-If <strong>E</strong> is an event upon which a command <strong>C</strong> waits, then <strong>E</strong>
-global-synchronizes-with <strong>C</strong>. In particular, if <strong>C</strong> waits on an event
-<strong>E</strong> that is tracking the execution status of the command <strong>C1</strong>, then
-memory operations done by <strong>C1</strong> will global-happen-before memory
-operations done by <strong>C</strong>. As an example, assume we have an OpenCL program
-using coarse-grain SVM sharing that enqueues a kernel to a host
-command-queue to manipulate the contents of a region of a buffer that
-the host thread then accesses after the kernel completes. To do this,
-the host thread can call clEnqueueMapBuffer to enqueue a blocking-mode
-map command to map that buffer region, specifying that the map command
-must wait on an event signaling the kernels completion. When
-clEnqueueMapBuffer returns, any memory operations performed by the
-kernel to that buffer region will global- happen-before subsequent
-memory operations made by the host thread.
-</p>
-</li>
-<li>
-<p>
-If a command <strong>C</strong> has an event <strong>E</strong> that signals its completion,
-then <strong>C</strong> global- synchronizes-with <strong>E</strong>.
-</p>
-</li>
-<li>
-<p>
-For a command <strong>C</strong> enqueued to a host-side command queue, if <strong>C</strong>
-has an event <strong>E</strong> that signals its completion, then <strong>E</strong> global-
-synchronizes-with an API call <strong>X</strong> that waits on <strong>E</strong>. For example, if a
-host thread or kernel-instance calls the wait-for-events function on
-<strong>E</strong>(e.g. the clWaitForEvents function called from a host thread)<strong>,*then
-*E</strong> global-synchronizes-with that wait-for-events function call.
-</p>
-</li>
-<li>
-<p>
-If commands <strong>C</strong> and <strong>C1</strong> are enqueued in that sequence onto an
-in-order command-queue, then the event (including the event implied
-between <strong>C</strong> and <strong>C1*due to the in-order queue) signaling *C*s
-completion global-synchronizes-with *C1</strong>. Note that in OpenCL 2.0, only
-a host command-queue can be configured as an in-order queue.
-</p>
-</li>
-<li>
-<p>
-If an API call enqueues a marker command <strong>C</strong> with an empty list
-of events upon which <strong>C</strong> should wait, then the events of all commands
-enqueued prior to <strong>C</strong> in the command-queue global-synchronize-with*C*.
-</p>
-</li>
-<li>
-<p>
-If a host API call enqueues a command-queue barrier command <strong>C</strong>
-with an empty list of events on which <strong>C</strong> should wait, then the events
-of all commands enqueued prior to <strong>C</strong> in the command-queue
-global-synchronize-with <strong>C</strong>. In addition, the event signaling the
-completion of <strong>C</strong> global-synchronizes-with all commands enqueued after
-<strong>C</strong> in the command-queue.

-<li>
-<p>
-If a host thread executes a clFinish call <strong>X</strong>, then the events
-of all commands enqueued prior to <strong>X</strong> in the command-queue
-global-synchronizes-with <strong>X</strong>.
-</p>
-</li>
-<li>
-<p>
-The start of a kernel-instance <strong>K</strong> global-synchronizes-with all
-operations in the work items of <strong>K</strong>. Note that this includes the
-execution of any atomic operations by the work items in a program using
-fine-grain SVM.
-</p>
-</li>
-<li>
-<p>
-All operations of all work items of a kernel-instance <strong>K</strong>
-global-synchronizes-with the event signaling the completion of <strong>K</strong>. Note
-that this also includes the execution of any atomic operations by the
-work items in a program using fine-grain SVM.
-</p>
-</li>
-<li>
-<p>
-If a callback procedure <strong>P</strong> is registered on an event <strong>E</strong>, then <strong>E</strong>
-global-synchronizes-with all operations of <strong>P</strong>. Note that callback
-procedures are only defined for commands within host command-queues.

-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>A map operation (clEnqueueMapBuffer or clEnqueueMapImage) performed on a

-<h3 id="_the_opencl_framework">3.4. The OpenCL Framework</h3>
-<div class="paragraph"><p>The OpenCL framework allows applications to use a host and one or more
-OpenCL devices as a single heterogeneous parallel computer system. The
-framework contains the following components:</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-OpenCL Platform layer: The
-platform layer allows the host program to discover OpenCL devices and
-their capabilities and to create contexts.
-</p>
-</li>
-<li>
-<p>
-OpenCL Runtime: The
-runtime allows the host program to manipulate contexts once they have
-been created.
-</p>
-</li>
-<li>
-<p>
-OpenCL Compiler: The
-OpenCL compiler creates program executables that contain OpenCL kernels.
-SPIR-V intermediate language, OpenCL C, OpenCL C++, and OpenCL C language versions from earlier
-OpenCL specifications are supported by the compiler. Other input
-languages may be supported by some implementations.
-</p>
-</li>
-</ul></div>
-<div class="sect3">
-<h4 id="_opencl_framework_mixed_version_support">3.4.1. OpenCL Framework: Mixed Version Support</h4>
-<div class="paragraph"><p>OpenCL supports devices with different capabilities under a single
-platform. This includes devices which conform to different versions of
-the OpenCL specification. There are three version identifiers to
-consider for an OpenCL system: the platform version, the version of a
-device, and the version(s) of the kernel language or IL supported on a
-device.</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>The platform version indicates the version of the OpenCL runtime that is
-supported. This includes all of the APIs that the host can use to
-interact with resources exposed by the OpenCL runtime; including
-contexts, memory objects, devices, and command queues.</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>The device version is an indication of the device&#8217;s capabilities
-separate from the runtime and compiler as represented by the device info
-returned by <strong>clGetDeviceInfo</strong>. Examples of attributes associated with
-the device version are resource limits (e.g., minimum size of local
-memory per compute unit) and extended functionality (e.g., list of
-supported KHR extensions). The version returned corresponds to the
-highest version of the OpenCL specification for which the device is
-conformant, but is not higher than the platform version.</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>The language version for a device represents the OpenCL programming
-language features a developer can assume are supported on a given
-device. The version reported is the highest version of the language
-supported.</p></div>
-<div class="paragraph"><p>Backwards compatibility is an important goal for the OpenCL standard.
-Backwards compatibility is expected such that a device will consume
-earlier versions of the SPIR-V and OpenCL C programming languages with
-the following minimum requirements:</p></div>
-<div class="olist arabic"><ol class="arabic">
-<li>
-<p>
-An OpenCL 1.x device must support at least one 1.x version of
-the OpenCL C programming language.
-</p>
-</li>
-<li>
-<p>
-An OpenCL 2.0 device must support all the requirements of an
-OpenCL 1.x device in addition to the OpenCL C 2.0 programming language.
-If multiple language versions are supported, the compiler defaults to
-using the highest OpenCL 1.x language version supported for the device
-(typically OpenCL 1.2). To utilize the OpenCL 2.0 Kernel programming
-language, a programmer must specifically set the appropriate compiler
-flag (-cl-std=CL2.0). The language version must not be higher than the
-platform version, but may exceed the device version (see section
-5.8.4.5).
-</p>
-</li>
-<li>
-<p>
-An OpenCL 2.1 device must support all the requirements of an
-OpenCL 2.0 device in addition to the SPIR-V intermediate language at
-version 1.0 or above. Intermediate language versioning is encoded as
-part of the binary object and no flags are required to be passed to the
-compiler.
-</p>
-</li>
-<li>
-<p>
-An OpenCL 2.2 device must support all the requirements of an
-OpenCL 2.0 device in addition to the SPIR-V intermediate language at

-allows the host and kernels executing on devices to directly share
-complex, pointer-containing data structures such as trees and linked
-lists. It also eliminates the need to marshal data between the host and
-devices. As a result, SVM substantially simplifies OpenCL programming
-and may improve performance.</p></div>

-<h4 id="_svm_sharing_granularity_coarse_and_fine_grained_sharing">5.6.1. SVM sharing granularity: coarse- and fine- grained sharing</h4>
-<div class="paragraph"><p>OpenCL maintains memory consistency in a coarse-grained fashion in
-regions of buffers. We call this coarse-grained sharing. Many platforms
-such as those with integrated CPU-GPU processors and ones using the
-SVM-related PCI-SIG IOMMU services can do better, and can support
-sharing at a granularity smaller than a buffer. We call this
-fine-grained sharing. OpenCL 2.0 requires that the host and all OpenCL
-2.2 devices support coarse-grained sharing at a minimum.</p></div>
-<div class="ulist"><ul>
-<li>
-<p>
-      Coarse-grained sharing:
-Coarse-grain sharing may be used for memory and virtual pointer sharing
-between multiple devices as well as between the host and one or more
-devices. The shared memory region is a memory buffer allocated using
-<strong>clSVMAlloc</strong>. Memory consistency is guaranteed at synchronization points
-and the host can use calls to <strong>clEnqueueSVMMap</strong> and <strong>clEnqueueSVMUnmap</strong>
-or create a cl_mem buffer object using the SVM pointer and use OpenCLs
-existing host API functions <strong>clEnqueueMapBuffer</strong> and
-<strong>clEnqueueUnmapMemObject</strong> to update regions of the buffer. What
-coarse-grain buffer SVM adds to OpenCLs earlier buffer support are the
-ability to share virtual memory pointers and a guarantee that concurrent
-access to the same memory allocation from multiple kernels on a single
-device is valid. The coarse-grain buffer SVM provides a memory
-consistency model similar to the global memory consistency model
-described in <em>sections 3.3.1</em> and <em>3.4.3</em> of the OpenCL 1.2
-specification. This memory consistency applies to the regions of buffers
-being shared in a coarse-grained fashion. It is enforced at the
-synchronization points between commands enqueued to command queues in a
-single context with the additional consideration that multiple kernels
-concurrently running on the same device may safely share the data.
-</p>
-</li>
-<li>
-<p>
-      Fine-grained sharing:
-Shared virtual memory where memory consistency is maintained at a
-granularity smaller than a buffer. How fine-grained SVM is used depends
-on whether the device supports SVM atomic operations.
-</p>
-</li>
-</ul></div>
-<div class="paragraph"><p>o   If SVM atomic operations are supported, they provide memory
-consistency for loads and stores by the host and kernels executing on
-devices supporting SVM. This means that the host and devices can
-concurrently read and update the same memory. The consistency provided
-by SVM atomics is in addition to the consistency provided at
-synchronization points. There is no need for explicit calls to
-<strong>clEnqueueSVMMap</strong> and <strong>clEnqueueSVMUnmap</strong> or <strong>clEnqueueMapBuffer</strong> and
-<strong>clEnqueueUnmapMemObject</strong> on a cl_mem buffer object created using the
-SVM pointer.</p></div>
-<div class="paragraph"><p>o   If SVM atomic operations are not supported, the host and devices can
-concurrently read the same memory locations and can concurrently update
-non-overlapping memory regions, but attempts to update the same memory
-locations are undefined. Memory consistency is guaranteed at
-synchronization points without the need for explicit calls to to
-<strong>clEnqueueSVMMap</strong> and <strong>clEnqueueSVMUnmap</strong> or <strong>clEnqueueMapBuffer</strong> and
-<strong>clEnqueueUnmapMemObject</strong> on a cl_mem buffer object created using the
-SVM pointer.</p></div>
-<div class="paragraph"><p>There are two kinds of fine-grain sharing support. Devices may support
-either fine-grain buffer sharing or fine-grain system sharing.</p></div>
-<div class="paragraph"><p>o   Fine-grain buffer sharing provides fine-grain SVM only within
-buffers and is an extension of coarse-grain sharing. To support
-fine-grain buffer sharing in an OpenCL context, all devices in the
-context must support CL_DEVICE_SVM_FINE_GRAIN_BUFFER.</p></div>
-<div class="paragraph"><p>o   Fine-grain system sharing enables fine-grain sharing of the hosts
-entire virtual memory, including memory regions allocated by the system
-<strong>malloc</strong> API. OpenCL buffer objects are unnecessary and programmers can
-pass pointers allocated using <strong>malloc</strong> to OpenCL kernels.</p></div>
-<div class="paragraph"><p>As an illustration of fine-grain SVM using SVM atomic operations to
-maintain memory consistency, consider the following example. The host
-and a set of devices can simultaneously access and update a shared
-work-queue data structure holding work-items to be done. The host can
-use atomic operations to insert new work-items into the queue at the
-same time as the devices using similar atomic operations to remove
-work-items for processing.</p></div>
-<div class="paragraph"><p>It is the programmers responsibility to ensure that no host code or
-executing kernels attempt to access a shared memory region after that
-memory is freed. We require the SVM implementation to work with either
-32- or 64- bit host applications subject to the following requirement:

-<div class="paragraph"><p>To ensure memory consistency in SVM allocations, the program can rely on
-the guaranteed memory consistency at synchronization points. This
-consistency support already exists in OpenCL 1.x and can be used for
-coarse-grained SVM allocations or for fine-grained buffer SVM
-allocations; what SVM adds is the ability to share pointers between the
-host and all SVM devices.</p></div>
-<div class="paragraph"><p>In addition, sub-buffers can also be used to ensure that each device
-gets a consistent view of a SVM buffers memory when it is shared by
-multiple devices. For example, assume that two devices share a SVM
-pointer. The host can create a cl_mem buffer object using
-<strong>clCreateBuffer</strong> with CL_MEM_USE_HOST_PTR and <em>host_ptr</em> set to the SVM
-pointer and then create two disjoint sub-buffers with starting virtual
-addresses <em>sb1_ptr</em> and <em>sb2_ptr</em>. These pointers (<em>sb1_ptr</em> and
-<em>sb2_ptr</em>) can be passed to kernels executing on the two devices.
-<strong>clEnqueueMapBuffer</strong> and <strong>clEnqueueUnmapMemObject</strong> and the existing
-access rules for memory objects (in <em>section 5.5.3</em>) can be used to
-ensure consistency for buffer regions (<em>sb1_ptr</em> and <em>sb2_ptr</em>) read and
-written by these kernels.</p></div>
-<div class="paragraph"><p>When the host and devices are able to use SVM atomic operations (i.e.
-CL_DEVICE_SVM_ATOMICS is set in CL_DEVICE_SVM_CAPABILITIES), these
-atomic operations can be used to provide memory consistency at a fine

-<div class="paragraph"><p>The OpenCL functions that are submitted to a command-queue are enqueued
-in the order the calls are made but can be configured to execute
-in-order or out-of-order. The _properties_argument in
-<strong>clCreateCommandQueueWithProperties</strong> can be used to specify the
-execution order.</p></div>
-<div class="paragraph"><p>If the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property of a
-command-queue is not set, the commands enqueued to a command-queue
-execute in order. For example, if an application calls
-<strong>clEnqueueNDRangeKernel</strong> to execute kernel A followed by a
-<strong>clEnqueueNDRangeKernel</strong> to execute kernel B, the application can assume
-that kernel A finishes first and then kernel B is executed. If the
-memory objects output by kernel A are inputs to kernel B then kernel B
-will see the correct data in memory objects produced by execution of
-kernel A. If the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property of a
-command-queue is set, then there is no guarantee that kernel A will
-finish before kernel B starts execution.</p></div>
-<div class="paragraph"><p>Applications can configure the commands enqueued to a command-queue to
-execute out-of-order by setting the
-CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE property of the command-queue.
-This can be specified when the command-queue is created. In
-out-of-order execution mode there is no guarantee that the enqueued
-commands will finish execution in the order they were queued. As there
-is no guarantee that kernels will be executed in order, i.e. based on
-when the <strong>clEnqueueNDRangeKernel</strong> calls are made within a
-command-queue, it is therefore possible that an earlier
-<strong>clEnqueueNDRangeKernel</strong> call to execute kernel A identified by event A
-may execute and/or finish later than a <strong>clEnqueueNDRangeKernel</strong> call to
-execute kernel B which was called by the application at a later point in
-time. To guarantee a specific order of execution of kernels, a wait on
-a particular event (in this case event A) can be used. The wait for
-event A can be specified in the <em>event_wait_list</em> argument to
-<strong>clEnqueueNDRangeKernel</strong> for kernel B.</p></div>
-<div class="paragraph"><p>In addition, a marker (<strong>clEnqueueMarkerWithWaitList</strong>) or a barrier
-(<strong>clEnqueueBarrierWithWaitList</strong>) command can be enqueued to the
-command-queue. The marker command ensures that previously enqueued
-commands identified by the list of events to wait for (or all previous
-commands) have finished. A barrier command is similar to a marker
-command, but additionally guarantees that no later-enqueued commands
-will execute until the waited-for commands have executed.</p></div>
-<div class="paragraph"><p>Similarly, commands to read, write, copy or map memory objects that are
-enqueued after <strong>clEnqueueNDRangeKernel</strong> or <strong>clEnqueueNativeKernel</strong>
-commands are not guaranteed to wait for kernels scheduled for execution
-to have completed (if the CL_QUEUE_OUT_OF_ORDER_EXEC_MODE_ENABLE
-property is set). To ensure correct ordering of commands, the event
-object returned by <strong>clEnqueueNDRangeKernel</strong> or <strong>clEnqueueNativeKernel</strong>
-can be used to enqueue a wait for event or a barrier command can be
-enqueued that must complete before reads or writes to the memory
-object(s) occur.</p></div>

-<h2 id="_appendix_b_portability">9. Appendix B Portability</h2>
-<div class="sectionbody">
-<div class="paragraph"><p>OpenCL is designed to be portable to other architectures and hardware
-designs. OpenCL has used at its core a C99 based programming language
-and follows rules based on that heritage. Floating-point arithmetic is
-based on the <strong>IEEE-754</strong> and <strong>IEEE-754-2008</strong> standards. The memory
-objects, pointer qualifiers and weakly ordered memory are designed to
-provide maximum compatibility with discrete memory architectures
-implemented by OpenCL devices.   Command-queues and barriers allow for
-synchronization between the host and OpenCL devices. The design,
-capabilities and limitations of OpenCL are very much a reflection of the
-capabilities of underlying hardware. </p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>Unfortunately, there are a number of areas where idiosyncrasies of one
-hardware platform may allow it to do some things that do not work on
-another. By virtue of the rich operating system resident on the CPU, on
-some implementations the kernels executing on a CPU may be able to call
-out to system services whereas the same calls on the GPU will likely
-fail for now. Since there is some advantage to having these services
-available for debugging purposes, implementations can use the OpenCL
-extension mechanism to implement these services.</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>Likewise, the heterogeneity of computing architectures might mean that a
-particular loop construct might execute at an acceptable speed on the
-CPU but very poorly on a GPU, for example. CPUs are designed in general
-to work well on latency sensitive algorithms on single threaded tasks,
-whereas common GPUs may encounter extremely long latencies, potentially
-orders of magnitude worse. A developer interested in writing portable
-code may find that it is necessary to test his design on a diversity of
-hardware designs to make sure that key algorithms are structured in a
-way that works well on a diversity of hardware.  We suggest favoring
-more work-items over fewer. It is anticipated that over the coming
-months and years experience will produce a set of best practices that
-will help foster a uniformly favorable experience on a diversity of
-computing devices.</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>Of somewhat more concern is the topic of endianness. Since a majority
-of devices supported by the initial implementation of OpenCL are
-little-endian, developers need to make sure that their kernels are
-tested on both big-endian and little-endian devices to ensure source
-compatibility with OpenCL devices now and in the future. The endian
-attribute qualifier is supported by the SPIR-V IL to allow developers to
-specify whether the data uses the endianness of the host or the OpenCL
-device. This allows the OpenCL compiler to do appropriate
-endian-conversion on load and store operations from or to this data.</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>We also describe how endianness can leak into an implementation causing
-kernels to produce unintended results:</p></div>
-<div class="paragraph"><p> </p></div>
-<div class="paragraph"><p>When a big-endian vector machine (e.g. AltiVec, CELL SPE) loads a
-vector, the order of the data is retained. That is both the order of
-the bytes within each element and the order of the elements in the
-vector are the same as in memory.  When a little-endian vector machine
-(e.g. SSE) loads a vector, the order of the data in register (where all
-the work is done) is reversed. *Both* the order of the bytes within
-each element and the order of the elements with respect to one another
-in the vector are reversed. </p></div>

-floating-point value lies outside the representable range of the integer
-type after rounding. When the <em>sat variant of the conversion is used,
-the float shall be converted to the nearest representable integer value.
- Similarly, OpenCL also makes recommendations about what should happen
-with NaN. Hardware manufacturers that provide the saturated conversion
-in hardware may use the saturated conversion hardware for both the
-saturated and non-saturated versions of the OpenCL convert</em> operator.
-OpenCL does not define what happens for the non-saturated conversions
-when floating-point operands are outside the range representable
-integers after rounding.

-The format of half, float,
-and double types is defined to be the binary16, binary32 and binary64
-formats in the draft IEEE-754 standard. (The latter two are identical to
-the existing IEEE-754 standard.) You may depend on the positioning and
-meaning of the bits in these types.

-OpenCL defines behavior
-for oversized shift values. Shift operations that shift greater than or
-equal to the number of bits in the first operand reduce the shift value
-modulo the number of bits in the element. For example,  if we shift an
-int4 left by 33 bits, OpenCL treats this as shift left by 33%32 = 1 bit.
