A great way to learn a technology, beyond reading about it or working through code samples, is by watching short recordings representing mini-tutorials that we call screencasts. These are essentially a recording of somebody's screen while they walk you through some code and explain concepts. We'll have many of those, and you'll be able to follow them on the C++ AMP channel9 tag (RSS).
Our first 4 C++ AMP screencasts accompany the first MSDN magazine article that I already mentioned on our blog, and here are the direct links to the screencasts:
If you have questions after watching them, we'd be happy to take them as usual in our online MSDN forum.
