Currently, the number of GPUs can only be set in the 
TORQUE_HOME/server_priv nodes file. Nothing is currently available to do 
a configuration on the MOM node.

GRES is separate from the nodes=$:ppn=$:gpu=$. GPUs can still be 
scheduled as a GRES and the :gpu=$ syntax not used. If you use the new 
syntax Moab 5.x will not run the job. It does not know what to do with 
it. I have not tried Maui but I expect it will do the same thing.

Who is the vendor of your GPU? We plan to have auto-detection support 
for NVIDIA soon.
