A parallel processing system with substantial computational power for the simulation of materials has been designed and constructed at Stony Brook. Although primarily designed to implement the molecular dynamics algorithm, the system is highly efficient in carrying out simulations that exhibit high degrees of local interaction. Our studies show that this system is capable of performance, for this application, which is comparable to the Cray-l at a small fraction of the cost.
