Dear Users,
On Monday we will make changes to the scheduler to increase the
initial priority of INCITE projects with a positive remaining balance
in order to help them use their time up before the end of the INCITE
allocation year. Jobs submitted under these projects will initially
have a higher priority than new jobs under negative INCITE or
discretionary projects would. However, this will not affect the rate
at which jobs accumulate priority over time so that all jobs will
still have a chance to run if they wait long enough.
This past Monday 'qstat' was modified to show the job priority (called
"Score") in the '-f' listing. This will help users in determining
when their job should run. Note that jobs with lower priority can
still run before those with higher priority if there is an opportunity
to backfill in which no other job with higher priority will fit. The
default sort order for the '-f' listing is now by increasing Score.
To revert to the old order of increasing JobID one can add '--sort
JobID' to the qstat command.
Thanks,
ALCF Support
