摘      要:In this article we recount the sequence of steps by which MPICH, a high-performance, portable implementation of the Message-Passing Interface (MPI) standard, was ported to the NEC SX-4, a high-performance parallel supercomputer. Each step in the sequence raised issues that are important for shared-memory programming in general and shed light on both MPICH and the SX-4. The result is a low-latency, very high bandwidth implementation of MPI for the NEC SX-4, In the process, MPICH was also improved in several general ways.
