Hi Jody
We don't have Mac OS-X, but Linux, not sure if this applies to you.
Did you configure your OpenMPI with Torque support,
and pointed to the same library that provides the
Torque you are using (--with-tm=/path/to/torque-library-directory)?
Are you using the right mpirun? (There are so many out there.)

Hi All,
I've been trying to get torque pbs to work on my OS X 10.5.7 cluster
with openMPI (after finding that Xgrid was pretty flaky about
connections). I *think* this is an MPI problem (perhaps via operator
error!)
If I submit openMPI with:
#PBS -l nodes=2:ppn=8
mpirun MyProg
pbs locks off two of the processors, checked via "pbsnodes -a", and the
job output. But mpirun runs the whole job on the second of the two
processors.
If I run the same job w/o qsub (i.e. using ssh)
mpirun -n 16 -host xserve01,xserve02 MyProg
it runs fine on all the nodes....
My /var/spool/toque/server_priv/nodes file looks like:
xserve01.local np=8
xserve02.local np=8
Any idea what could be going wrong or how to debu this properly? There
is nothing suspicious in the server or mom logs.
Thanks for any help,
Jody
