Using Graphics Processing Units (GPUs) for general-purpose computing has made high-performance parallel computing very cost-effective for a wide variety of applications. However, programming these highly-parallel processors still remains somewhat of an art.
We have several projects investigating how GPUs can be applied to different application domains, including:
- Lattice Boltzmann simulations and other geoscience applications, working with the University of Minnesota's Geofluids Group
- Accelerating data deduplication in high-performance archival storage systems with g-Dedu
- Establishing an Nvidia CUDA Teaching Center
- Evaluating the performance of GPU clusters with the Minnesota Supercomputing Institute
