Abstract

We present the design for the NXU Ultracomputer, a shared-memory MIMD parallel maohlne composed of thousands of autonomous processing elements. This machine uses an enhanced mesaage switching network with the geometry of ap Omega-network to approximate the ideal behavior of Schwartz's paracomputer model of computation and to implement efficiently the important fetch-and-add synchronization primitive. We outline the hardware that would be required to build a 4096 processor syatem using 1990's technology. We also discuss system software issues, and present analytic studies of the network performance. Finally, we include a sample of our effort to implement and simulate parallel variants of Important scientific program.
