[slurm-users] fail when trying to set up selection=con_res

[Ethan Van Matre]

I've been trying to setup a slurm cluster with con_res enabled. No luck.

Running on ubuntu 16.04

When using linear selection all works as expected. Jobs are schedules and run their course then exit. Exclusive use of the node is granted.

We would like to schedule based on cpu (cores actually) and set thus:


# SCHEDULING

FastSchedule=1

SchedulerType=sched/backfill

#SchedulerPort=7321

#SelectType=select/linear

SelectType=select/cons_res

SelectTypeParameters=CR_CORE

#SelectTypeParameters=CR_CPU


When launching jobs we more than one at a time per node but the jobs become hung in a COMPLETING state. Not sure if they ever started.


Can anyone point me to how to set up slurm so that allocation is on a cpu (core) basis with as many jobs as there are cores running on each node?
