| <p>OpenCL (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>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.</p> |
| </div> |
| <div class="paragraph"> |
| <p>OpenCL consists of an API for coordinating parallel computation across |
| heterogeneous processors; and a cross-platform programming language with a |
| well-specified computation environment.</p> |
| </div> |
| <div class="paragraph"> |
| <p>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 subset of ISO C99 with extensions for parallelism</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>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> |
