Description Doug Jacobsen 2016-04-13 07:14:45 MDT 
Hello,

I just tried to upgrade slurm on cori to 15.08.10 but it crashed as soon as I brought up the "regular" partition owing to some incompatibilities between the bf_min_prio_reserve patch we have and some modifications made in 15.08.10 reverting nearby logic.


In particular the segfault occurred in backfill.c:

                job_ptr->part_ptr = part_ptr;
                job_ptr->priority = job_queue_rec->priority;

when job_queue_rec is accessed after it is xfreed() earlier.

I both really need the bf_min_prio_reserve and I need to be able to upgrade 15.08.  Would it be possible that we can get an update of this patch?  or better, get bf_min_prio_reserve mainlined into 15.08 HEAD?

I'm attaching the mildly hacked up patch I'm using on top of 15.08.10.

I'm in a bit of a jam on cori now, because we are up, but I can't redeploy or get some of the other patches unless I revert changes to my build system...


Thank you for your help with this,
Doug
