In this paper, we present the design and implementation of a multiprocessor simulator written in the language SimCal. We use the simulator to test our scheme to partition a sequential program for parallel execution on a shared memory, asynchronous multiprocessor. The results of the simulations indicate that our partitioning scheme can provide significant speed-up by executing the program in parallel. We then execute the partitioned program on an actual multiprocessor and find a high degree of correlation between the simulations and the actual executions. This correlation serves to validate our simulator. We then use the multiprocessor simulator to hypothetically extended the actual multiprocessor and we show that adding more processors will not provide significant improvement in the parallel executions unless the communication structure is also improved to contain more parallelism.
