Persistent communication is an optimization for point to point message passing. This module describes when it is appropriate, how it reduces system overhead, and how it is used in a program. Improvement in wallclock time for IBM's MPI on the SP is documented. In the lab exercises, you will modify a code to use persistent communication, and compare the timing for the original and optimized version.
