C++ AMP (Accelerated Massive Parallelism) is a native-programming model that contains elements that span the C++ programming language and its runtime library. It provides an easy way to write programs that compile and execute on data-parallel hardware such as graphics cards (GPUs).
Built on the Windows DirectX platform and expected to be part of the next Visual C++ compiler, this is not only a great new tool for the upcoming Visual Studio 11 release, as previously mentioned, it's also an open specification:
Microsoft announced publication, under the Microsoft Community Promise license, of the C++ AMP open specification. This release means compiler developers and vendors now have the ability to implement C++ AMP in their compilers, just as Microsoft has done, broadening access for C++ developers everywhere to the possibilities offered by heterogeneous hardware.
