Introduction

Velocity Scheduler, or vsched, is the batch system for the CTC computing environment. Submitting jobs to vsched is the only way to access the compute nodes. The serial vsched module details how to use the batch system to submit and run serial jobs.

In this module:

  • differences between serial and parallel batch jobs
  • two ways of starting parallel jobs on the batch system
    • by setting up the run interactively
    • by using a batch script

Prerequisites: The use of vsched to run serial jobs was covered in this module. You should understand these materials before continuing with this topic.

Velocity Scheduler, or vsched, is the batch system for the CTC computing environment. Submitting jobs to vsched is the only way to access the compute nodes. The serial vsched module details how to use the batch system to submit and run serial jobs. This module will expand on that information. First, the differences between serial and parallel batch jobs will be explained. We will cover two ways of starting parallel jobs on the batch system; by setting up the run interactively or by using a batch script. Examples are used throughout the module, which is followed by a lab exercise.
