 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.
 .
 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 consists of an API for coordinating parallel computation across
 heterogeneous processors; and a cross-platform programming language with a
 well-specified computation environment. The OpenCL standard:
 .
  - Supports both data- and task-based parallel programming models
  - Utilizes a subset of ISO C99 with extensions for parallelism
  - Defines consistent numerical requirements based on IEEE 754
  - Defines a configuration profile for handheld and embedded devices
  - Efficiently interoperates with OpenGL, OpenGL ES, and other graphics APIs
 .
 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.
 .
