would setting resources_max.nodect=4 for the queue in torque do what you need? --Joe

Running Maui 3.2.619 with torque 2.3.5 on our small cluster. I have three queues configured for students (we are a university). I want to limit the number of nodes and processors students may use within the configured queue. For example, I have a short queue (called student_short) and I want to restrict the number of nodes per user to 4. I've tried the following based upon what I've read in the Maui policy note as well as the parameter guide: changeparam CLASSCFG[student_short] MAXPROC=32 MAXJOB=32 MAXIJOB=32 MAXNODEPERUSER=4,4 Yet, when I submit a test job requesting more than four nodes: qsub -V -l nodes=6:ppn=2 -q student_short my_script the job executes with the allocation of six nodes: argo14-4/1+argo14-4/0+argo13-3/1+argo13-3/0+argo13-2/1+argo13-2/0+argo7-4/1 +argo7-4/0+argo7-2/1+argo7-2/0+argo7-1/1+argo7-1/0 My understanding is the "MAXPROC" applies not to a single job but to the totality of all jobs running in the queue. If I have sixteen jobs in the queue, those jobs can use no more than 32 processors. And, for each user, no more than 4 nodes per (both soft and hard set to four on the MAXNODEPERUSER).
