Abstract : Computer simulation results of a parallel system conducting beamforming for a linear hydrophone array are presented. These studies were performed to determine the best mapping and partitioning of a sequential beamformer program onto a parallel system. Different partition designs and programming methodologies were examined, as well as latencies caused by inter- processor communications. Results of these simulation studies demonstrate that linear scalability in performance is possible by programming with host-node methodology and utilizing efficient inter-processor communications.
