Could you send the contents of a PBS_NODEFILE from a Torque 2.3.7
allocation, and the man page for tm_spawn?
My only guess would be that something changed in those areas as we
don't really use anything else from Torque, and run on Torque-based
clusters in production every day. Not sure what version we have here,
though I believe it is pretty current (will check).
You also might want to configure OMPI 1.3.3 with --enable-debug. You
could then do a run with -mca ras_base_verbose 5 -mca plm_base_verbose
5 --debug-daemons on your mpirun cmd line to get a step-by-step
diagnostic output of the interaction with Torque. Should give us some
idea of where the failure is occurring.

hi,
I have the following problem:
I am using openmpi 1.3.3
programs (directly and from scripts) submitted with mpiexec are
running
fine.
programs (directly and from scripts) submitted through Torque 2.3.7
with openmpi compiled with --with-tm (and torque-devel) installed
give segfaulting of the programs.
programs submitted through Torque 2.3.7 directly with openmpi
compiled without --with-tm (and NO torque-devel installed) run fine
however mpiexec programs from script (script submiited through torque)
are only running on 1 node, so I need openmpi compiled with --with-tm
We also have a cluster running with openmpi 1.2.9 compiled without
--with-tm in combination with torque 2.3.3 and everything is running
fine, so NO segfaults and mpiexec from script also running on the
nodes selected at submitting time.
I don't have errors on log files only on the job log file:
---------------------------------------------------------------------------
mpiexec noticed that process rank 7 with PID 3150 on node
rugem21.chem.rug.nl exited on signal 11 (Segmentation fault).
--------------------------------------------------------------------------
Could anyone please help me,
many thanks in advance
