In defer mode, the main scheduling loop runs once per minute, but most
of your jobs will typically be scheduled by the backfill scheduler
instread (although that depends upon your configuration). The backfill
scheduler typically test far more jobs since it can periodically
reliquish locks to let other RPCs be processed, while the main
scheduling loop just gives up after a few seconds. Use
SchedulingParameters=bf_interval=#,... to specify the frequency at
which the backfill scheduler runs.
I'll make the main scheduling loop frequency configurable in the next
release, but today it is not configurable without changing the code.
See the variable PERIODIC_SCHEDULE in src/slurmctld/slurmctld.h if you
care to change the frequency today.
Quoting Paul Edmon <[email protected]>:
So if you are running in defer mode for the scheduler what
determines the frequency of the main loop for the scheduler? Can
this be changed?
