Multicomputer applications utilize both the computation and communication facilities of the multicomputer to solve a given problem. It follows that the overall performance of any hypercube is a dependent on its computation and communication performance, as well as the interaction of the two. The communication performance of first generation message passing machines limited the range of applications that could be run efficiently on those systems. Second generation multicomputers promise a greater range of applicability. To characterize this range it is necessary to understand the computation and communication properties of the underyling hardware and software. This report contains a detailed comparison of the computation and communication performance of two commercially-available hypercube multiprocessors, the Intel iPSC and Intel iPSC/2. For some tests, results for an Ncube/four hypercube are also included. The benchmarks include measures of C and FORTRAN processor performance, link level communication characteristics, and network level communication performance. The performance to two hypercube application programs is also examined.
