ACENET Summer School - MPI: Glossary

A typical MPI process calculates which other processes it will communicate with.

If there is a closed loop of procs sending to one another, there is a risk of deadlock.

All sends and receives must be paired, at time of sending.

There are advanced MPI routines that solve most common problems. Don’t reinvent the wheel.

Collective operations involve all processes in the communicator.

Finite differences, stencils, guard cells.
