• MaxTime change
  

  • Audience: Cluster users

  • Impact: In order to improve scheduling efficiency and stability, we will be setting a maximum run time on all partitions that have MaxTime set to UNLIMITED to a MaxTime of 3 days. The unrestricted partition will be set to 365 days. Partitions that already have MaxTime set will retain their current setting. Partition owners wishing to set a different MaxTime for their partition should contact FASRC. Note that we do no guarantee uptime and so users should utilize checkpointing to save state in case of node failure.
