GENERAL MAINTENANCE

• Slurm upgrade to 22.05.3
  • Audience: All cluster job users 
  • Impact: Jobs and the scheduler will be paused during upgrade and resume once maintenance completes
• tempfs change in Slurm (Cannon - This already exists in FASSE)
  • Audience: All cluster job users who use local (on node) /tmp scratch
  • Impact: After this change, any job using /tmp on a node will now have its own virtual slice of /tmp (does not currently affect /scratch).
    This will affect jobs that try to share data across nodes by using /tmp. More details: https://slurm.schedmd.com/job_container.conf.html
