Title: Tapping the supercomputer under your desk
Description: "This paper shows how to build algorithms that use graphics processing units (GPUs) installed in most modern computers to solve dynamic equilibrium models in economics.  In particular, we rely on the compute unified device architecture (CUDA) of NVIDIA GPUs.  We illustrate the power of the approach by solving a simple real business cycle model with value function iteration.  We document improvements in speed of around 200 times and suggest that even further gains are likely"--National Bureau of Economic Research web site.
