Analysis of packet-switched multiple-bus multiprocessor systems

Performance analyses of packet-switched multiple-bus multiprocessor systems are presented. Approximate queuing network models are developed for both synchronous and asynchronous control schemes, and the results are shown to be in good agreement with simulation results. The analysis of the synchronous system is based on a decomposition technique, with each of the shared resources in the system being represented as a single-server queue. For asynchronous systems, the analysis is based on the flow equivalence technique. Numerical results obtained from the analyses indicate that packet-switched multiple-bus multiprocessors with only a few buses perform almost as well as crossbar-based multiprocessors
