Hello,
Is it possibly to dynamically adjust job priority based on the amount
of running jobs for a specific user?
Example:
All jobs have default priority of 100.
User A has 2 jobs running and one job queued. The queued job receives
-2 priority because this User A already has 2 jobs running.
Maui does not have this possibility. If you want to take into
consideration the resources used by running jobs, your best bet is to
use the FS component (fairshare usage). You will have to use one or
several of the subcomponents FSUSER, FSGROUP, FSACCOUNT, FSQOS and
FSCLASS. You could also use the USAGE component (subcomponents CONSUMED,
REMAINING, PERCENT or EXECUTIONTIME).
See page http://docs.adaptivecomputing.com/maui/5.1.2priorityfactors.php
for more details.
Moab has a subcomponent (or subfactor) of FS called FSJPU (current
active jobs associated with job user) that seems to be what you want,
but Maui does not have it.
