What is MPI, and where can I find information about using it on Big Red?

Message Passing Interface (MPI) is a library specification for message passing. The goal of MPI is to develop a practical, portable, efficient, and flexible standard for writing message-passing programs. For more, see the Argonne National Laboratory (ANL) MPI page.

For an MPI tutorial, see Introduction to MPI on the National Center for Supercomputing Applications (NCSA) Cyberinfrastructure Tutor (CI-Tutor) web-based training site. Everyone is welcome to take the course, but you must register first.

For information about using MPI on Big Red at Indiana University, see:

• On Big Red, how do I run MPI jobs?
• The "Parallel applications and message passing libraries" section of Getting started on Big Red
• Using the paralleljob command to submit jobs
