Our group has been active in the area of parallel computing and commodity parallel computing since the earliest days. We were involved in the original Beowulf project and built the first one outside of NASA Goddard Space Flight Center and the very first one to use CPUs other than Intel. Four generations of zBox computers have provided a local experimental platform. It has also let our students experience building supercomputers.
We currently have 1PB of data on spinning disk and have moved as much data from a single simulation to the Johns Hopkins Datascope for visualization and analysis.
