[torqueusers] Torque is not handling jobs to nodes

[Brock Palen]

Maybe your openMPI did not fine the location of libtorque when it was  
built.

run the command:

ompi_info

And make sure you see something like:

MCA ras: tm (MCA v1.0, API v1.3, Component v1.2.7)
MCA pls: tm (MCA v1.0, API v1.3, Component v1.2.7)

If you do then your openmpi has tm (pbs/torque) support to start jobs.
If not, and you have libtorque in a non standard location rebuilt  
openmpi with:

./configure --with-tm=/path/to/torque
