Abstract :
A complete prototype implementation of MPI on the IBM Scalable Power PARALLEL 1 and 2 (SP1, SP2) is discussed. This implementation achieves essentially the same performance as the native EUI library, although MPI is much larger. The paper describes the implementation of EUI on SP1/SP2, and the modifications required to to implement MPI, initial performance measurements, and directions for future work
