Hi,
I am currently trying to set up OpenMPI in torque. OpenMPI is build with
tm support. Torque is correctly assigning nodes and I can run
mpi-programs on single nodes just fine. the problem starts when
processes are split between nodes.
For example, I create an interactive session with torq
can confirm tm is used.
Before invoking mpirun, you might want to cleanup the ompi directory in
/tmp
Cheers,
Gilles

Can you run
mpirun --mca plm_base_verbose 10 ...
So we can confirm tm is used.

Btw, what is the output of

On a00551 ?
Out of curiosity, is a previous version of Open MPI (e.g. v1.10.4)
installled and running correctly on your cluster ?

Hi Gilles,
Thanks for th
f you use the same hostfile, or some hostfile as
an explicit argument when you run mpirun from within the torque job?

Hi Gilles,
Thanks for the hint with the machinefile. I know it is not equivalent
and i
do not intend to use
an “openmpi”
directory underneath that one, and the mca_xxx libraries are down
there

Hi Gilles,
I do not have this library. Maybe this helps already...

Hi,
i reconfigured to only have one physical node. Still no success, but
the nodefile now looks better. I still get the errors:

Hi,
okay lets reboot, even though Gilles last mail was onto something.
The problem is that i failed starting programs with mpirun when more
than one node was involved. I mentioned that it is likely some
configuration problem with my server, especially authentification(we
have some kerberos ni
