<p>The comparative performance is studied of different message passing system designsexperimentally on a shared memory Encore Multimax multiprocessor. The systems aremeasured both by benchmarks and by running example parallel applications. To act as acontrol, the shared memory machine results are compared with the performance of thebenchmarks and applications on the Intel iPSC/2 running the NX/2 operating system. Thedesign alternatives considered are buffering, buffer organization, reference and valuesemantics, synchronization, coordination strategy and the location of the system in useror kernel space. The results include measurements of the effects of the designalternatives, memory caching, message sizes and copying.</p>
