Hi, a different question-- again, I am using OGS/GE 2011.11p1 on ROCKS. We have
a small cluster with a combination of 12- and 16-core blades. If I do:
qsub -pe orte 60
with no jobs on the cluster, what gets allocated is usually sub-optimal;
instead of 3*16+12 (4 full nodes), I might get 2*16+2*12+4 (4 full nodes and
one partial).
Is there a general way to force allocation of the minimum possible number of
nodes, other than requesting the nodes explicitly?
No.
You could check in the beginning of the job script whether the granted
allocation suits you, or otherwise reschedule the job (after a random wait
maybe).

We're already using exclusive scheduling, so this would make a lot more sense.
This feels like a newb question but I haven't found an answer by searching.
$ qconf -sp orte
pe_name orte
slots 9999
user_lists NONE
xuser_lists NONE
start_proc_args /bin/true
stop_proc_args /bin/true
allocation_rule $fill_up
control_slaves TRUE
job_is_first_task FALSE
urgency_slots min
accounting_summary TRUE
Thanks,
Noah
