Hi Jon,

You can use MTT to do performance testing only.  Here is a good
starting point for using MTT:


Thanks for the pointer!

Have you tried running trivial tests with your MPI installation?

Yes. I've run various benchmarks and the Infiniband diagnostic
programs (not that I always understand their output).
But, one of our users is reporting that a standard
Chemistry application is not scaling as expected when
going to a second node after filling up the first node.
This is on a Rocks cluster with 12-cores per node.
I figured that doing some more comprehensive MPI tests
would be a good place to start.

Were you planning on submitting the results to the open-mpi.org database?

No. This is just informal testing.
