At the AMD Fusion Developer Summit 2011 in June, Microsoft announced C++ Accelerated Massive Parallelism (C++ AMP), an extension to C++ for parallel programming of GPU’s. This extension, included in Visual Studio 11, would allow developers to program the GPU with language features that are arguably much more powerful than either CUDA or OpenCL. In comparison, CUDA and OpenCL seem more like stone knives and bearskins. After what seemed like an long three-month wait, Microsoft has finally released the Visual Studio 11 Developer Preview, which contains C++ Accelerated Massive Parallelism (C++ AMP), Microsoft’s vision of GPU programming. Was it worth the wait?
