Abstract

A survey of parallel programs written for an experimental hypercube indicates that while systolic dataflow programs map well to a hypercube, general purpose programs with random dataflow are seriously constrained by the cost of communication. This paper proposes the augmentation of the hypercube architecture with a special-purpose communications coprocessor that provides hardware support for distributed objects. We anticipate this will increase the efficiency of inter-process communication primitives by a factor of 100.
