Hello,
Is there a way to modify how GE selects which host(s) to run jobs on? For example, if I
have one user submit 10 6-core jobs, can I make sure GE fills up one host before kicking
jobs onto another, instead of "randomly" placing them on separate nodes? I
only have 18 hosts so I'd like to leave as many hosts completely free for other users as
possible.
Yep, there are a few ways. Assuming you are using parallel environments
for those 6-core jobs, you can modify the PE "allocation_rule" to be
"$pe_slots", which should do what you want. Each job will use N slots
(as requested), but only on a single node
You can also try the special value "$fill_up" will do soemthing similar,
but allow slots to "overflow" into the next node.
Thanks,
Brett
