New User Warnings:

  1. If you have never used a Cluster, or are not familiar with this cluster, YOU WILL WANT to read and follow the examples below to become familiar with how to run jobs on HPC. It is a common practice by new users to ignore this manual and simply try to run jobs without understanding what they are doing. Such carelessness can and WILL easily impact on critical jobs and users currently running on the cluster. If your actions compromise the health of the HPC cluster, your account will be LOCKED so please make sure you run through the examples below before you embark on running jobs.
  2. Do NOT use the Master nodes for work. If everyone does this, the Master nodes will crash keeping HPC users from being able to login to the cluster.
  3. Do NOT use your home-directory (/home/$USER) for any serious work.
  4. Never submit large number of jobs (greater than 2) without first running a small test case to make sure all works as expected. Start slow and then ramp up with jobs once you are familiar with how things work.
  5. Before you use the cluster and/or ask for help, PLEASE make sure you run the Serial Job example explained below before contacting HPC support.
