Hi Joe:
Per your request I confirm (with help from the e-mail that is sent when
specifying ‘-m e’) that a regular ‘qdel job-ID’ uses KILL (9):
Job 5493527 (sleeper) Aborted
Exit Status = 137
Signal = KILL
User = hughmac
Queue = all.q@mysgehost00001
Host = mysgehost00001
Start Time = 01/23/2014 12:15:37
End Time = 01/23/2014 12:15:45
CPU = 00:00:00
Max vmem = 204.609M
failed assumedly after job because:
job 5493527.1 died through signal KILL (9)
From the ‘qdel man’ page:
-f Force deletion of job(s). The job(s) are deleted from the list
of
jobs registered at sge_qmaster(8) even if the sge_execd(8)
control-
ling the job(s) does not respond to the delete request sent
by
sge_qmaster(8).
So without the ‘-f’ a request for a KILL is sent from the master to the execd,
and the job isn’t removed from the master DB if that request fails (but maybe
it is when the execd comes back up on the node?), while with the ‘-f’ the job
IS removed from the master DB even if the request for a kill sent to the execd
by the master fails. I find ‘-f’ useful if an exec node is down for a long
period of time and I want to clean up the output of qstat (after notifying
users of the demise of their job(s)).
Cheers, Hugh

Subject: [gridengine users] What signal does qdel send to the job?
I thought it would be 15 for qdel and 9 for qdel -f.
But, it seems, that it's always 9, as I can't catch which ever signal is being
sent.
Can someone confirm, please?
