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.

No. This is just informal testing.
