Line 39: [[OpenCL]] is an industrial standard which was originally proposed by [[Apple Inc.]] and is maintained and developed by the [[Khronos Group]] now.<ref>{{cite web\|title = OpenCL – The open standard for parallel programming of heterogeneous systems\|url = https://www.khronos.org/opencl/\|website = www.khronos.org\|accessdate = 2015-11-05}}</ref> OpenCL provides [[C++]] like [[Application programming interface\|APIs]] for programming different devices universally, including GPGPUs. [[File:OpenCL program execution flow.jpg\|alt=Illustrating the execution flow of a OpenCL program/kernel\|thumb\|OpenCL program execution flow\|285x285px]] The following figure illustrates the execution flow of launching an OpenCL program on a GPU device. The CPU first detects OpenCL devices (GPU in this case) and than invokes a just-in-time compiler to translate the OpenCL source code into target binary. CPU then sends data to GPU to perform computations. When the GPU is processing data, CPU is free to process its own tasks. === C++ Amp ===
