[Mauiusers] nodeaccesspolicy based on queue and job?

On my large cluster with a global "NODEACCESSPOLICY SINGLEJOB", I'm
trying to meet a specific requirement of letting single-proc jobs within
a specific class share nodes. This should be transparent to the user
and not require additional arguments to qsub (from TORQUE).
I can't think of a way to do this purely in maui.cfg. It seems like I
should able to do this with a QOS, but it doesn't seem possible.
Other possibilities that I can think of include:
- In TORQUE, single-proc jobs go through a routing queue that adds
NACCESSPOLICY:SHARED to the RM extensions (doesn't seem possible).
- In TORQUE, route single-proc jobs to a different execution queue, then
maui.cfg has "CLASSCFG[foo] NODEACCESSPOLICY SHARED" (also doesn't
- A qsub filter that adds "-W x=NACCESSPOLICY:SHARED" for single-proc
jobs in the correct queue.
Anyone have any suggestions for me?
