Subject: Re: [OMPI users] torque pbs behaviour...

Oops - I should have looked at your output more closely. The component_find
warnings are clearly indicating some old libs laying around, but that isn't
why your job is hanging.

The reason your job is hanging is sitting in the orte-ps output. You have
multiple processes declaring themselves to be the same MPI rank. That
definitely won't work.

The question is why is that happening? We use Torque all the time, so we
know that the basic support is correct. It -could- be related to lib
confusion, but I can't tell for sure.

Can you rebuild OMPI with --enable-debug, and rerun the job with the
following added to your cmd line?

-mca plm_base_verbose 5 --debug-daemons -mca odls_base_verbose 5

I'm afraid the output will be a tad verbose, but I would appreciate seeing
it. Might also tell us something about the lib issue.
