Bharath, Can you send the output of "mpiexec -info"? I'm particularly interested in whether mpiexec recognizes pbs as a possible launcher or not. If it recognizes pbs as a launcher, it should automatically select it where possible. -- Pavan On 04/17/2013 02:21 PM US Central Time, Bharath Ramesh wrote:

Bharath,

(sorry on road real quick)

I do this with hydra+mvapich with Matlab and it does work.

In my case I didn't find how to tell hydra when building mpich/mvapich to tell it where libtorque.so lives.

To resolve this I download hydra alone and build it giving explicit options to it to find the torque library. Then you get the expected behavior. I don't have the directions for how I did this handy. Thanks for the pointer, I will dig into this to see if I can get hydra to work correctly. Currently I do pass the option --with-pbs=/path/to/torque to the mvapich2 configure line.
