Still haven't solved this problem. Again, here is the scenario: A system reservation is in place for 10 days from now.
Users submit jobs for say 15 days and land in the top of the IDLE stack (showq) Other jobs which are submited, say for 2 days or 4 hours, are sitting behind the 15 day jobs waiting to run. The jobs holding everything up were submitted to a CLASS with preemptor QOS. Removing the system reservation allows everything to run. Manually placing the long running jobs on HOLD allow the rest to run. My BACKFILLDEPTH more than covers all the jobs in the IDLE state as indicated by the asterisk next to job number. Other maui configurations on other clusters, without this preemptor stuff, work as expected. I'm out of clues here! The relevant stanza from maui.cfg looks like this: BACKFILLPOLICY BESTFIT BACKFILLMETRIC PROCSECONDS BACKFILLDEPTH 20 RESERVATIONPOLICY FIRSTFIT RESERVATIONDEPTH[0] 24 RESDEPTH 24 Any clues on what I might be missing?
