Hello,

I have reconfigured torque to disable NUMA support. I am able to run single
node single processor job(nodes=1:ppn=1). But when i am trying to run
multiprocessor jobs(nodes=2:ppn=2 with nodes having 2 and 8 ncpu), the job
is remaining in queue . I am able to forcefully run the job via qrun. I am
using Maui scheduler.  Can anyone please tell me what may be the issue? is
it something to do with Maui scheduler? Thanks.

Regards,
Hitesh Chugani.
