I am reposting a message I originally posted a couple of months ago as there was no response and I have yet to solve this. Any help is appreciated.

(Note all jobs are serial) Cluster configuration: /var/spool/pbs/server_priv/nodes: node001 np=2 all compute opteron node002 np=2 all compute opteron node003 np=2 all compute opteron node004 np=2 all compute opteron node005 np=2 all compute opteron node006 np=2 all compute opteron When idle, pbstop reports: Usage Totals: 0/12 Procs, 0/6 Nodes, 0/0 Jobs Running Node States: 6 free I am spawning jobs using: qsub -l walltime=15:00,nodes=1:ppn=1 script.pbs If I spwan more than 6 jobs as a single user, only 6 will run at any time, the remainder stay queued. However, another user can run jobs on the cluster using the remaining 6 processors. So it seems that users are being prevented from using more than a single processor on a node. Running 7 jobs, pbstop reports: Usage Totals: 6/12 Procs, 6/6 Nodes, 6/7 Jobs Running Node States: 6 free Relevant lines from /usr/local/maui/maui.cfg NODELOADPOLICY ADJUSTSTATE NODEALLOCATIONPOLICY CPULOAD NODEACCESSPOLICY SHARED NODEMAXLOAD 1.75 NODECFG[DEFAULT] MAXJOB=3 MAXJOBPERUSER=2 USERCFG[DEFAULT] MAXJOB=8,12 How can I configure (or use?) maui to allow a user to run more than 6 jobs at a time?
