MPI - Message Passing Interface

MESSAGE PASSING INTERFACE

Distributed parallel systems with dedicated switching networks are one of the most promising directions for high-performance scalable parallel computers. However, programming distributed parallel systems is more complex than writing sequential programs, due to different vendor-dependent message-passing libraries and tools. MPI (Message Passing Interface), the recently introduced standard for message-passing systems, now ensures portability over many platforms. It provides point-to-point communication, collective communication, virtual process topologies and support for writing heterogenous parallel applications.

MPI-F Programming Environment

MPI-F is an MPI implementation for the IBM SP2. It consists of the MPI communications library and a unified tracing tool (UTE) for tracing application code without source code modification, analysis and visualization of trace events. MPI-F is installed at every major SP2 installation. It implements the latest standard definition. MPI-F is the base for the MPI product under POE.2.1, now available for the SP2 running AIX-4.1.
