I'm having a problem running OpenMPI under Torque. It complains like there is a command syntax problem, but the three variations below are all correct, best I can tell using mpirun -help. The environment in which the command executes, i.e. PATH and LD_LIBRARY_PATH, is correct. Torque is 2.3.x. OpenMPI is 1.2.8. OFED is 1.4.
Somewhere in the FAQ I had read that you must not give -machinefile under Torque with OpenMPI 1.2.8 and you did not need to give -np. That's why I tried variation 3 below without either of these options, but it still fails.
Thanks for any help
