we'd like to submit jobs on a load balanced basis. We set
NODEALLOCATIONPOLICY to CPULOAD.
When we submit a job and there are enough fully free nodes, then
everything is ok, the job is running. But if there aren't enough fully
free nodes - only partially free nodes are available, the job doesn't
run. It is in the idle state.
A job requests -l nodes=4:ppn=3
Available nodes (every node has 8 CPUs):
Nodes# Free CPUs
The requested resources are available, but the job doesn't run.
The output of checkjob 8970:

cannot select job 8970 for partition DEFAULT (startdate in '00:00:01')
We changed NODEALLOCATIONPOLICY from CPULOAD to MINRESOURCES and the job
started immediately. But we'd like to use load balance.
