GPU2 WU's in "production mode"

As of last Monday, the GPU2 projects (both NVIDIA and ATI) have been in production mode, which means that we've moved on from testing to direct research on them.  The ATI cards have bee in production for a while (more than one month before) and we're starting to write our first peer reviewed scientific paper deriving from the results.

We're very excited about the GPU2 possibilities right now, since we are getting incredible production from GPU2 clients.  Once the first paper has been formally accepted by peer review, I'll talk more about the results.
