Intel was really pushing parallel computing stuff a year or two ago. But they've been a bit quiet about it recently.
For DB3, I'm looking in to OpenCL, which basically means I can dump things to the GPU to calculate. I'm pretty sure that a sim that could take 1-2 seconds per frame on the CPU could run at 60 FPS or better with a good graphics card installed churning through the calculations. But I'm holding off doing any of that actual work until I have a sim up and running and can get some actual ideas about what parts of the sim are going to be slow (I'd assume the big three will be DNA, physics, and vision).
