[slurm-users] One node is not used by slurm

[Mahmood Naderan]

Hi,
Although compute-0-0 is included in a partition, I have noticed that
no job is offloaded there automatically. If someone intentionally
write --nodelist=compute-0-0 it will be fine.

# grep -r compute-0-0 .
./nodenames.conf.new:NodeName=compute-0-0 NodeAddr=10.1.1.254 CPUs=32

Compute-0-0 is idle. So, why slurm decided to put those jobs on other nodes?
Any idea for debugging?
