HPL can "stress test" the MPI, but it is typically relatively
insensitive to MPI performance. The usual use produces a measure of the
peak floating-point performance of the system.
A broader set of system performance measurements are found in the HPCC
(HPC Challenge) tests, which include HPL. Many of these tests, however,
still don't really focus on MPI performance.
Tests that focus on MPI performance include the OSU tests.

Benchmarks (formerly Pallas).
The NAS Parallel Benchmarks offer more "application-level" tests.

It takes some effort to configure and run it.

I am wondering if there is some stress testing software for OpenMPI I
can use to run on a cluster to give me an idea of the performance
level of the system?
