OpenCL, (Open Computing Language)
an open standard for cross-platform, task-based as well as data-based parallel programming of CPUs, GPUs, FPGAs, DSPs, including the C99 based programming language OpenCL C. OpenCL C forbids recursion, and omits function pointers, bit fields and variable-length arrays, but has fixed-length vector types, supporting SIMD instructions if available on the target platforms. OpenCL 2.0 adds features like nested parallelism and shared virtual memory, version 2.1 extends OpenCL C to a subset of C++14. OpenCL 3.0 makes version 1.2 functionality a mandatory baseline with 2.x and 3.x as optional features and replaces 'OpenCL C++' with 'C++ for OpenCL' as a subset of C++171. OpenCL is maintained by the nonprofit technology consortium Khronos Group, adopted by Apple2, Intel, Qualcomm, AMD, Nvidia, Altera, Samsung, Vivante, Imagination Technologies and ARM.

OpenCL to Vulkan
The OpenGL graphics API specified by Khronos Group is deprecated in favor for Vulkan, since Vulkan and OpenCL v1.2/v2.x share SPIR-V as an intermediate representation it is possible to cross-compile OpenCL code via SPIR-V to run on Vulkan enabled devices 3.
