Re: [slurm-users] Slurm Upgrade Philosophy?

Hi Jason, Ultimately each site decides how/why to do it; in my case I tend to do big "forklift upgrades", so I'm running 18.08 on the current cluster and will go to latest SLURM for my next cluster build. But you may have good reasons to upgrade slurm more often on your existing cluster. I don't
