Abstract

This paper presents a comparison of two implementations of the MPI standard [1] for message passing: MPI/Pro, a commercial implementation of the MPI standard from MPI Software Technology, Inc., and MPICH, an open source, high-performance, portable MPI implementation. This paper reviews key distinguishing architectural features of the two MPI implementations and presents comparative performance results from micro benchmarks and real applications. A discussion on the impact of MPI library architecture on performance is also offered.
