peterb:
Some deep background on collision detection math, and how to do it fast; well its from nvidea they benefit from explaining it.

Although couldnt see the link in the article but the above url reads GPU... and yes its done in CUDA so this routine offloads the CPU !!!!

Numsgil:
Yep, GPUs are really really powerful for a very, very narrow range of problems  Physics being one of those problems.  I plan to (eventually) leverage CUDA to improve the performance of some of the core algorithms for DB3.
