We have a cluster with multi-core nodes (168) that can be shared by multiple jobs at the same time. How do I configure a partition such that it only accepts jobs requesting up to (say) 8 cores, but will run multiple jobs at the same time? The following is apparently not working: PartitionName=debug Nodes=node01 MaxTime=02:00:00 DefMemPerCPU=1000 MaxCPUsPerNode=8 Default=NO It allows one job using 8 cores, but a second one will not start because the limit is apparently for the partition as a whole.
