() is the director of the Terascale Computing Facility and an Associate Professor in the Department of Computer Science at Virginia Tech
. He joined the Department of Computer Science in August 1999. His research interests are in the area of high performance computer systems. In particular, fault tolerance in large-scale distributed systems, network emulation, network routing algorithms, compiler directed frameworks and parallel simulation algorithms. He currently heads the Computing Systems Research Laboratory and serves as a core faculty in the Laboratory for Advanced Scientific Computing and Applications. He is also the architect of System X
, one of the world's fastest and least expensive supercomputers.
Achievements & Awards
He was the lead designer of Virginia Tech’s supercomputer, System X, ranked in November 2003 as the fastest supercomputer at any University in the world. He conceived the idea to use off-the-shelf commercial products to design a supercomputer and built his system in a little less than three months. He targeted price/performance since he did not have the hundreds of millions of dollars available to him that it took to build the world's current top two supercomputers.
The number one supercomputer, Japan’s Earth Simulator, was estimated to cost between $250 and $350 million, and the Department of Energy’s ASCI-Q, a dedicated weapons facility in the number two slot, had an estimated construction cost of $215 million. When... Read More
