| <h2>Notes</h2> |
| <p> |
| The devices associated with the program object are the devices associated with <code class="varname">context</code>. |
| </p> |
| <p> |
| OpenCL allows applications to create a program object using the program source or binary and build appropriate program executables. This allows applications to determine whether they want |
| to use the pre-built offline binary or load and compile the program source and use the executable |
| compiled/linked online as the program executable. This can be very useful as it allows |
| applications to load and build program executables online on its first instance for appropriate |
| OpenCL devices in the system. These executables can now be queried and cached by the |
| application. Future instances of the application launching will no longer need to compile and |
| build the program executables. The cached executables can be read and loaded by the |
| application, which can help significantly reduce the application initialization time. |
| </p> |
| <p> |
| An OpenCL program consists of a set of kernels that are identified as functions declared with the <a class="citerefentry" href="functionQualifiers.html"><span class="citerefentry"><span class="refentrytitle">__kernel</span></span></a> qualifier in the program source. OpenCL programs may also contain auxiliary functions and constant data that can be used by <a class="citerefentry" href="functionQualifiers.html"><span class="citerefentry"><span class="refentrytitle">__kernel</span></span></a> functions. The program executable can be generated <span class="emphasis"><em>online</em></span> or <span class="emphasis"><em>offline</em></span> by the OpenCL compiler for the appropriate target device(s). |
