While MPI is the most common mechanism for expressing parallelism, MPI programs are not composable by using current MPI process managers or parallel shells. We introduce MPISH2, an MPI pro- cess manager analogous to serial Unix shells. It allows the composition of MPI and serial Unix utilities with one another to perform scalable tasks across large numbers of Unix clients. This paper discusses in detail issues of process management and parallel tool composition.
