Queueing System

All jobs on AHPCC clusters which require a significant amount of CPU or memory should be submitted through the queueing system. In general, two types of jobs may be passed into the queue:

  • A batch job - a specific command is executed on the node(s) assigned to the job without the need for user interaction. A vast majority of jobs ran on the HPC clusters are batch jobs.
  • An interactive job - a login shell is started on the first node assigned to the job. The user, in turn, specifies the commands to execute at the command prompt.

All compute nodes in the Razor and Trestles clusters are divided into groups of nodes called queues.
