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.
