I don't know why that happens (other than you're opening a comment and
not closing it, IIUC), but it would probably be less surprising to just
reject the submission than reduce the limit.
In the (rare...) case the user actually needs all the time requested,
you risk wasting resources. If you reject the job, user can decide to
change to another queue.

Hello,
I’m writing a small lua script that for modify “TimeLimit” of a submited
job if user has configured a TimeLimit bigger that configured in the
partition. So, is TimeLimit for partition is, for example, 4 hours
(04:00:00) and user submit his/her job with a TimeLimit of 5 hours, lua
script modify this submit and forces “TimeLimit” to 4 hours for avoiding
that job remains at queue in state “pending” with reason “Partition Time
Limit…”.
I have written these lines:
function slurm_job_submit(job_desc, part_list, submit_uid)
--[[ my id is 1008; for testing purposes, lua only applies
to me --]]
if (job_desc.user_id == 1008) then
slurm.log_info("Submit job by me")
--[[ I check partition --]]
if (job_desc['partition'] == "nodo.q") then
--[[
if (job_desc['time_limit'] > 14400)
job_desc['time_limit'] = 14400
end
end
end
return slurm.SUCCESS
end
However, if I submit a job with TimeLimit of 5 hours, lua script doesn’t
modify submit and job remains “pending”…
What am I doing wrong?
Thanks.
