Design Options for Interconnecting a 100+ TFlop/sec Parallel Supercomputer in 2004

Abstract

As part of the Department of Energy’s efforts to eliminate the need for nuclear testing, the DOE’s “Accelerated Strategic Computing Initiative” is funding the purchase of a series of extremely-high-performance computers from 1996 through 2004. These machines are expected to help the DOE ensure the safety, reliability, and performance of the nuclear weapons stockpile using computation-based methods, rather than testing-based methods.
