Hi Reuti.
Hi William.
here's my settings you required:
params MONITOR=1
max_reservation 32
default_duration 0:10:0
I cannot understand how What I see in ${SGE_ROOT}/${SGE_CELL}/common/schedule
can help me.. here's a little extract for a job submitted with -R y, and it
keeps repeating without change
...
3653372:1:RESERVING:1489043424:660:P:smp:slots:32.000000
3653372:1:RESERVING:1489043424:660:Q:long.q@node19.cluster:slots:32.000000
3653372:1:RESERVING:1489043424:660:P:smp:slots:32.000000
3653372:1:RESERVING:1489043424:660:Q:long.q@node19.cluster:slots:32.000000
What else is running in the cluster? Are there other jobs blocked which would
otherwise slip in? All request -l h_rt=…?
Hi.
There are always smaller jobs (without -R y) pending in the queue that
get in front of bigger jobs (with -R y).
The user of this big job doesn't make use of options like h_rt,
mem_free, etc.. but only asks for a particular node, ie:
hostname=node19.cluster
(When no job requests -l h_rt=… and only the default length apply [which won't
be enforced], SGE might look for another node to make the reservation.)
the other users usually use -l h_rt=.. and mem_free=.. and as they are
serial jobs or parallel jobs that asks less resources, they slip in
front of the job that asks more resources even if it was submitted long
before and makes use of -R y.
One more question. how can I understand that something is moving with
reservation (ie see that the scheduler has started reserving slots) by
looking in the file ${SGE_ROOT}/${SGE_CELL}/common/schedule ?
Thank you.
Roberto
