[slurm-users] Prevent users from updating their jobs

Hi everyone,

I was wondering if there is a way to prevent users from updating their jobs
with "scontrol update job".

Here is the justification.

A hypothetical user submits a job requesting a regular node, but
he/she realises that the large memory nodes or the GPU nodes are idle.
Using the previous command, users can request the job to use one of those
resources to avoid waiting without a real need for using them.

Any suggestions to prevent that?



sbatch --mem=1G -t 0:10:00 --wrap="srun -n 1 sleep 360"
scontrol update job 791 Features=smp

[user01 at slurm-simulator ~]$ sacct -j 791 -o "jobid,nodelist,user"
       JobID        NodeList      User
------------ --------------- ---------
791                    smp-1    user01
-------------- next part --------------
