Things to do

• Use the scheduler! (i.e. do not ssh to nodes to run)
• Give good estimates of your job’s needs. If your job can be split into smaller sections, you may get scheduled sooner, as the scheduler will try to backfill shorter jobs.
• Limit use of interactive sessions
• Checkpoint your job if possible
• Make use of local storage on the nodes for intermediate results

Things NOT to do

• Run jobs on the head node
• Many simultaneous writes to network filesystem- use local scratch if you can!
• Go around scheduler and run directly on the nodes
