Re: [OMPI users] job runs with mpirun on a node but not if submitted via Torque.

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,

Re: [OMPI users] job runs with mpirun on a node but not if submitted via Torque.

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 have no idea why your
