Why Are PVM and MPI So Di erent


PVM and MPI are often compared These comparisons usu ally start with the unspoken assumption that PVM and MPI represent di erent solutions to the same problem In this paper we show that in fact the two systems often are solving di erent problems In cases where the problems do match but the solutions chosen by PVM and MPI are di erent we explain the reasons for the di erences Usually such di er ences can be traced to explicit di erences in the goals of the two systems their origins or the relationship between their speci cations and their implementations
