As CUDA improved, Hanweck Associates' Hanweck says, he began developing options pricing, Monte Carlo simulation and other quantitative models. "And the speed improvements we were getting over a regular desktop were 50 to 100 times faster," he claims. "These were just ordinary video cards geared to gamers. But then [Nvidia] tacked on the CUDA language and they could perform all these calculations."

As a result, the financial services industry is exploring new ways of obtaining more HPC cycles while keeping power demands in check, following the lead of HPC pioneers such as universities and the Department of Defense. Among this diverse wave of new HPC offerings are software that helps applications take advantage of parallel processors and graphics boards, PCI (peripheral component interface) cards and Cell processors that handle portions of HPC tasks. Also among the next generation of products is Microsoft's latest cluster server, which is designed to extend HPC to more applications and workers.
