It's my site. I didn't realize it was even posted here (I did post it at reddit).

To address some points:

The title of the site is kind of vague, agreed. I'm going to write an abstract for the index page to describe the gist of the design methodologies.

It's not part of an NVIDIA sales pitch, at all. I work in NVIDIA Research and have a lot of autonomy. I like doing programming patterns and algorithms research. At some point I had amassed a lot of stuff and thought it would be nice to share everything with the community.. no coordination with the marketing folks. My employer was nice enough to let me release it, but this is my project, not an official company one. This flexibility is one advantage of working in research.

I don't want to get dragged into a vendor or API debate. The MGPU project is about programming concepts. It wouldn't be hard for a developer to translate all the functions into another API--"hackability" is a goal that I talk about in the introduction. I chose CUDA because it's succinct (important for code readability) and its what I use on a daily basis.
