Hi,
is it possible to have slurm scheduling jobs automatical according to the "-t" time requirements to a fitting partition?
e.g. 3 partitions
PartitionName=standard Nodes=c-[01-10] Default=YES MaxTime=04:00:00 DefaultTime=00:10:00 State=UP OverSubscribe=NO PartitionName=medium Nodes=c-[04-08] Default=NO MaxTime=24:00:00 DefaultTime=04:00:00 State=UP OverSubscribe=NO PartitionName=long Nodes=c-[09-10] Default=NO MaxTime=336:00:00 DefaultTime=24:00:00 State=UP OverSubscribe=NO
So in the standard partition which is the default we have all nodes and a max time of 4h, in the medium partition we have 4 nodes with a max time of 24h and in the long partition we have 2 nodes with a max time of 336h.
I was hoping that if I submit a job with -t 01:00:00 it can be run on any node (standard partition), whereas when specifying -t 05:00:00 or -t 48:00:00 the job will run on the nodes of the medium or long partition respectively.
However, my job will not get scheduled at all when -t is greater than 01:00:00
i.e.
]$ srun --cpus-per-task 1 -t 01:00:01 --pty bash srun: Requested partition configuration not available now srun: job 42095 queued and waiting for resources
it will wait forever because the standard partition is selected, I was thinking that slurm would automatically switch to the medium partition.
Do I misunderstand something there? Or can this be somehow configured.
Thanks so much and sorry for the naive question Dietmar
