TransPAC Distributed Simulation Analysis Among Scientists in Germany, US and Japan The High Performance Computing Center Stuttgart and Sandia National Laboratories have been researching, prototyping, and applying a distributed parallel supercomputing and collaborative virtual-reality computation steering environment since 1996. The output of a metacomputing simulation is visualized by means of a distributed virtual collaborative environment. People and machines have the potential to interact via a virtual reality-based, online, on-demand service anywhere in the world. The project recognizes the unique combination of high-end resources and high-speed connectivity to networks spanning multiple continents, including Computer Services for Academic Research Centre (Manchester, UK), the Centre of Virtual Environments at University of Salford (UK), Tsukuba Advanced Computing Center (Japan) and Pittsburgh Supercomputing Center (USA). The applications emphasize some of the largest supercomputers in the world being networked to support International Grand Challenge applications, and advanced visualization and collaboration tools being utilized to develop the workplace of the 21st Century.
