SC ’97 Metacomputing Between the U.S. and Germany The Pittsburgh Supercomputing Center (PSC) and Sandia National Laboratories (SNL) are creating an international metacomputing environment with the Rechenzentrum Universitaet Stuttgart (RUS), which will be demonstrated at the SC97 conference in San Jose, CA, in November. The three sites will utilize a connection spanning the vBNS, CA*netII, ESnet, and a transatlantic connection from Teleglobe. Intended as a prototype for international high-performance networking, the project couples Pittsburgh’s 512-processor CRAY T3E with another 512-processor T3E at the High Performance Computing Center in Stuttgart and a Paragon at SNL. They will visualize fluid dynamics simulations of the reentry of a space vehicle; the entry of meteorites into the Earth’s atmosphere as well as their impact on the Earth; and ab-initio calculations of magnetic properties of alloys.
