Numerical Simulator III – Building a Terascale Distributed Parallel Computing Environment for Aerospace Science and Engineering

. We at National Aerospace Laboratory of Japan have operated a distributed memory parallel supercomputer consisting of 166 vector processors and 280Gflop/s peak performance for aerospace science and engineering since 1993. We are now in the transition phase to the next generation terascale system. The next system is a SMP-cluster type distributed parallel system consisting of about 1800 scalar processors and having 9.3Tflop/s peak performance and 3 TB user memory, and its full operation is scheduled at October 2002. The new system is called Numerical Simulator III having characteristic properties in various system aspects from data management through visualization. In this paper, we briefly review the history of Numerical Simulator, and describe the new terascale distributed parallel computing environment for aerospace science and engineering.
