[Developers] A possible GPU project

[Matthew Supernaw]

I did some GPU computing a few years ago for the park service. The big
problem was that not all GPU/GPU drivers where created equal.
Stability was a major issue. I haven't looked into it for a while, but
maybe they have all the bugs worked out? We mostly used Nvidia FX
3800, which have 192 cores. Two FX 3800 per computer in a linux
cluster, that was an awesome amount of power! I currently don't have
access to any OpenCL/CUDA capable GPUs. I'll be happy to look into it
when my development machine arrives!
