Oh interesting. I remember that Folding@Home way back then (ca 2009) was already testing protein folding on GPUs and it took advantage of CUDA. I never really thought much of it other than how cool it was that my mid-tier Nvidia graphics card could be used for something else other than games, but this explains how this ended up happening.

(Bit of a tangent, but that project was very influential in getting me interested in computer science because, wow, how cool is it that we can use GPUs to do insane parallel computing. So I guess, very very indirectly, Nvidia had a part in me being a software engineer today.)
