...that would interfere with users 'logging in' to a job to check on it
though, wouldn't it? I mean we do have pam_slurm_adopt configured but I
still tell people it's preferable to use 'srun --jobid=XXXX --pty
/bin/bash' to check what a specific job is doing as pam_slurm_adopt
doesn't seem to inherit things like the job-local tmp dir and such :(.
So I'd at least check if it's an existing JobID you're trying to connect to.

Hi Peter,
as Rémi said, the way to do this in Slurm is via a job submit plugin. For
example in our job_submit.lua we have
if (job_desc.partition == "cpu" or job_desc.partition == "gpu") and job_desc.qos ~=
"admin" then
if job_desc.script == nil or job_desc.script == '' then
slurm.log_info("slurm_job_submit: jobscript is missing, assuming
interactive job")
slurm.log_info("slurm_job_submit: CPU/GPU partition for interactive job,
abort")
slurm.log_user("submit_job: ERROR: interactive jobs are not allowed in the
CPU or GPU partitions. Use the interactive partition")
return -1
end
end
Which checks to see if the job script exists - this is more or less the
definition of an interactive job.

slurm newbie here, converting from pbspro. In pbspro there is the capability of
limiting interactive jobs (i.e srun) to a specific queue (i.e partition).
Note that in Slurm, srun and interactive jobs are not the same things. The srun
command is for creating steps of jobs (interactive or not), optionally creating
a job allocation beforehand if it does not exist.
You can run interactive jobs with salloc and even attach your PTY to a running
batch job to interact with it. On the other hand, batchs jobs can create steps
using srun command.
I don't know any native Slurm feature to restrict interactive jobs (to a
specific partition or whatever). However, using job_submit LUA plugin and a
custom LUA script, you might be able to accomplish what you are expecting. It
has been discussed here:
