That would be of value, but is currently not supported.
Quoting Damien François <[email protected]>:
Hello all,
Slurm allows resizing jobs with 'scontrol update jobid=$SLURM_JOB_ID
NumNodes=1' as described here:
http://slurm.schedmd.com/slurm_ug_2011/Advanced_Usage_Tutorial.pdf .
That works without problem.
However, we share nodes (SelectType = select/cons_res;
SelectTypeParameters = CR_CORE_MEMORY ) so I was trying to do
something like 'scontrol update jobid=$SLURM_JOB_ID numtasks=1' or
'scontrol update jobid=$SLURM_JOB_ID numcpus=1' but it does not seem
possible to do that while the job is running. I have messages like
"slurm_update error: Requested operation is presently disabled" or
"Update of this parameter is not supported: NumTask=1"
Am I doing it wrong? Are there alternatives?
Thanks in advance
