: 17 A single compute device typically consists of several compute units, which in turn comprise multiple processing elements (PEs). Functions executed on an OpenCL device are called " kernels".
It defines a C-like language for writing programs. OpenCL views a computing system as consisting of a number of compute devices, which might be central processing units (CPUs) or "accelerators" such as graphics processing units (GPUs), attached to a host processor (a CPU).
Conformant implementations are available from Altera, AMD, ARM, Creative, IBM, Imagination, Intel, Nvidia, Qualcomm, Samsung, Vivante, Xilinx, and ZiiLABS. OpenCL is an open standard maintained by the non-profit technology consortium Khronos Group. OpenCL provides a standard interface for parallel computing using task- and data-based parallelism. OpenCL specifies programming languages (based on C99, C++14 and C++17) for programming these devices and application programming interfaces (APIs) to control the platform and execute programs on the compute devices. OpenCL ( Open Computing Language) is a framework for writing programs that execute across heterogeneous platforms consisting of central processing units (CPUs), graphics processing units (GPUs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs) and other processors or hardware accelerators.
