EARLY APPLICATIONS IN THE MESSAGE-PASSING INTERFACE (MPI)

We describe a number of early efforts to make use of the Message-Passi ng Interface (MPI) standard in applications, based on an informal surv ey conducted in May-June, 1994. Rather than a definitive statement of all MPI developmental work, this paper addresses the initial successes , progress, and impressions that application developers have had with MPI, according to the responses received. We summarize the important a spects of each survey response, and draw conclusions about the spread of MPI into applications. An understanding of message passing and acce ss to the MPI standard are prerequisites for appreciating this paper. Some background material is provided to ease this requirement.
