The difference you are seeing here indicates that the "direct" run is
using the rsh launcher, while the other run is using the Torque
launcher.
So I gather that by "direct" you mean that you don't get an allocation
from Maui before running the job, but for the other you do? Otherwise,

Another small thing that I noticed. Not sure if it is relevant.
When the job starts running there is an orte process. The args to this
process are sli

Thanks Ralph! I'm sorry my first post lacked enough specifics. I'll
try my best to fill you guys in on as much debug info as I can.

So do we. In fac
It is very hard to debug the problem with so little information. We
regularly run OMPI jobs on Torque without issue.
Are you getting an allocation from somewhere for the nodes? If so, are
you using Moab to get it? Do you have a $PBS_NODEFILE in your
environment?

I've a strange OpenMPI/Torque problem while trying to run a job on our
Opteron-SC-1435 based cluster:
Each node has 8 cpus.
If I got to a node and run like so then the job works:
mpirun -np 6 ${EXE_PATH}/${DACAPOEXE_PAR} ${ARGS}
Same job if I submit through PBS/Torque then it starts running but
