Sounds like a problem in PLPA - I'll have to defer to them. Our
primary PLPA person is on vacation this week, so you might not hear
back from him until later next week when he gets through his inbox
mountain.
PLPA may have its own mailing list too - not really sure.

Looking at your command line, did you remember to set -mca

Ahh, no, sorry, still feeling my way with this..
If not, we won't set affinity on the processes.
Now it fails immediately with:
Setting processor affinity failed
--> Returned "Invalid argument" (-11) instead of "Success" (0)
wrapped in a bunch of OpenMPI messages explaining that it
failed on start.
The strace looks much the same as before.
