Message-Passing Interface (MPI)
The Message-Passing Interface (MPI) is a standard architecture and programming interface for designing distributed applications. Silicon Graphics, Inc. supports MPI in the POWERChallenge Array product. For details on MPI in Silicon Graphics systems, see the World-Wide Web page http://www.sgi.com/Products/PowerChallengeArray/TechInfo/MPI/. For the MPI standard, see http://www.mcs.anl.gov/mpi/index.html.
The performance of both sockets and MPI depends on the speed of the underlying network. The network that connects nodes (systems) in an Array product has a very high bandwidth.
