What is MPI, and where is it available at IU?

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.
