Hi Robert, Do you have the following line in your maui config?
ENABLEMULTIREQJOBS TRUE I believe it is require to request multiple resources.

When I submit a job on multiple nodes specifying them in a certain why my job gets blocked by Maui, otherwise it runs just fine. Here's the line I usually use in submission script to submit jobs to mutliple nodes (say if I need 16 cores): "#PBS -l nodes=2:ppn=8". That works just fine. But when I don't need a multiple of 8 processors and don't want to block processors unnecessarily, I tried the following (say to get 20 cores): "#PBS -l nodes=2:ppn=8+1:ppn=4" According to the Torque user manual that should get me 16 cores on 2 nodes and 4 cores on the third. I can submit it without a problem, but then it is blocked by Maui. For testing I also tried "#PBS -l nodes=1:ppn=1+1:ppn=1" and "#PBS -l nodes=1:ppn=8+1:ppn=8", which are blocked as well Output from showq for the blocked job: ================================================================ BLOCKED JOBS---------------- JOBNAME USERNAME STATE PROC WCLIMIT QUEUETIME 1272 robert BatchHold 1 00:00:30 Tue Mar 29 18:06:47 ================================================================ The relevant policies (as far as I know), which are set in maui.cfg, are: NODEACCESSPOLICY SHARED JOBNODEMATCHPOLICY EXACTNODE Please, can anybody point me to where the problem might be? If there are queue specific settings that could cause this, I'd be more than happy to provide more information. Thanks, Robert PS: I am aware that I could just reserve multiple of 8 processors and let some of them sit idle, but on our relatively small cluster that amounts to s significant waste of resources. -- Robert Jacobi Research Assistant University of Arizona Department of Aerospace & Mechanical Engineering 1130 N.
