________________________________ Maui Users, I have a 36 Node systems with 8 to 12 cores in each node and have users submit up to 1000 jobs at a time. The issue is that the cluster will only run about 90 of them at a time with 85 out of the 344 processors active and only 12 of the nodes being used. The jobs are all going to the default queue and there are no node or cpu/memory parameters added to the submissions. Each job runs for about 20 min. Any ideas on how to get maui to schedule more jobs to the nodes?
