This paper presents an empirical study of the performance of various approaches to distributed discrete event simulation on a message-passing multiprocessor. This study compares the performance of distributed simulation to a sequential simulation of exactly the same system.Four simulation benchmarks are presented. Each is a closed queueing network with a different topology. Four implementations of each benchmark are described--each with a different lookahead. Each benchmark was run under three customer loads. Each benchmark was run using one, two, four, and eight processors. This paper presents data showing the relationships between speedup , number of processors, lookahead, and computation load.
