MPI on IBM SP1/SP2: current status and future directions
Hubertus Franke, Peter Hochschild, Pratap Pattnaik, Jean-Pierre Prost, Marc Snir · 2002
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.>
