Subject: Re: [OMPI users] Torque and OpenMPI 1.2

Andrew,
     That worked like a champ. Now my users can have it both ways. For the
record, my control statements looked like the following:

/opt/openmpi-1.2.4/bin/mpirun -mca pls ^tm -np $NP -hostfile $PBS_NODEFILE
$my_binary_path

My job works just fine and reports no errors. This version of OpenMPI was
built with "--with-tm=/usr/local/pbs".

              Thanks for your help,
               Pat
