Hi,
I only have access to this test system for another 24 hours or so so I'm
not sure it's worth any more of your efforts. Coupled with the fact that
I don't have root on the system in question it could be more work too
figure out whats going on than its worth.
Thanks for your help so far,
-stephen

That's truly odd -- I can't imagine why you wouldn't get the TCP
transport with the above command line. But the latencies, as you
mentioned, are far too low for TCP.
To be absolutely certain that you're not getting the IB transport, go
to the $prefix/lib/openmpi directory and make a bogus subdirectory
(e.g., "mkdir foo"). Then move the *openib* and *mvapi* components
into that subdirectory (you'll likely only have either "openib" *or*
"mvapi" -- not both).
Then try running again.
What is stranger still is that I can't find any *openib* or *mvapi*
components in that subdirectory so I'm left wondering what exactly
it's
using to communicate. I don't think it's using shared memory because
I've run a shared memory test aswell and the latencies are lower
with that.
Perhaps it's interacting with something else installed somewhere on
the
system?
