[slurm-users] slurm.conf - listing nodes

[Steve Brasier]

Hi all,

Is there any disadvantage to listing nodes explicitly in slurm.conf rather
than using hostlist expressions, either in the Partition or Node
definitions?

E.g. if we have lots of compute nodes is doing:

PartitionName=compute \
    Nodes=\
    compute-0,\
    compute-1,\
    ...
    compute-999
NodeName=DEFAULT <default options here>
NodeName=compute-0
NodeName=compute-1
...
NodeName=compute-999

any worse from slurms point-of view than using compute[0-1000]?

>From my reading of the slurm.conf manpage
<https://slurm.schedmd.com/slurm.conf.html> using NodeName=DEFAULT is
important for scheduling performance but I'm not sure about explicit node
names vs hostlist expressions.

many thanks
