C++ AMP (C++ Accelerated Massive Parallelism)
C++ AMP (C++ Accelerated Massive Parallelism) accelerates the execution of your C++ code by taking advantage of the data-parallel hardware that's commonly present as a graphics processing unit (GPU) on a discrete graphics card. The C++ AMP programming model includes support for multidimensional arrays, indexing, memory transfer, and tiling. It also includes a mathematical function library. You can use C++ AMP language extensions to control how data is moved from the CPU to the GPU and back.
Note
C++ AMP headers are deprecated starting with Visual Studio 2022 version 17.0.
Including any AMP headers will generate build errors. Define _SILENCE_AMP_DEPRECATION_WARNINGS before including any AMP headers to silence the warnings.
