Abstract

We present the design for the NYU ultracomputer, a general-purpose MIMD parallel processor composed of thousands of autonomous processing elements. This machine uses an enhanced omega-network to approximate the ideal behavior of Schwartz's paracomputer model of computation and to effeciently implement the important replace-add synchronization primitive. The novelty of the design lies in the enhanced network, in particular in the constituent switches and interfaces. We also present the results of analytic and simulation studies of the network as well as including a sample of our efforts to implement parallel variants of important scientific codes.
