Hi, I am Daniel Moth 
This screencast assumes knowledge of the C++ AMP API, e.g. that you totally understand the matrix multiplication implementation in C++ AMP. So if you satisfy that prerequisite, watch this screencast on what features are available in Visual Studio 2012 for debugging C++ AMP code.
To learn more please visit the C++ AMP blog, and we encourage C++ AMP questions in the Parallel Computing in C++ and Native Code MSDN forum.
