This paper describes an implementation of a parallel molecular dynamics algorithm on the CM2 Connection Machine that is designed for large-scale simulations. The method employs a cell subdivision of the simulation region, and is partly based on the layer approach developed for vector processing. All communication is between adjacent processing elements, eliminating the need for global communication. Performance measurements were made with systems containing over 106 particles.
