Job priority of 1 is no longer used as a special case in slurm v2.4

The commit 8b14f388 on Jan 19, 2011 is causing problems with Moab cluster-scheduled machines. Under this case, Moab hands off every job submitted immediately to SLURM which gets a zero priority. Once Moab schedules the job, Moab raises the job's priority to 10,000,000 and the job runs. When you happen to restart the slurmctld under such conditions, the sync_job_priorities() function runs which attempts to raise job priorities into a higher range if they are getting too close to zero. The problem as I see it is that you include the "boost" for zero priority jobs. Hence the problem we are seeing is that once the slurmctld is restarted, a bunch of zero priority jobs are suddenly eligible. So there becomes a disconnect between the top priority job Moab is trying to start and the top priority job SLURM sees. I believe the fix is simple: diff job_mgr.c~ job_mgr.c 6328,6329c6328,6331 < while ((job_ptr = (struct job_record *) list_next(job_iterator))) < job_ptr->priority += prio_boost; --- while ((job_ptr = (struct job_record *) list_next(job_iterator))) { if (job_ptr->priority) job_ptr->priority += prio_boost; } Do you agree?

honored correctly. I also put in nice notes where the values aren't to be altered.

* Specify MinNodes via "scontrol update partition". * Whenever the zero-node allocation ends, the frontend node is left in a state of COMPLETING until scontrol reconfigure is issued (this doesn't appear to impact the performance of the front end node as other jobs can still be submitted including other zero-node jobs).

Cray - Add support for zero compute note resource allocation to run batch script on front-end node with no ALPS reservation. Useful for pre- or post- processing. NOTE: The partition must be configured with MinNodes=0.

Sinfo output format of "%P" now prints "*" after default partition even if no field width is specified (previously included "*" only if no field width was specified. Added output format of "%R" to print partition name only without identifying the default partition with "*").
