How to Read the History

  • Job ID
  • Type: Job type
  • Finish Time: Date and time when the job completed
  • Elapsed Time: Time taken for job execution
  • Resources: Information about CPU/GPU usage
  • Wall Time: Maximum execution time that was set
  • Working Directory: Link to the working directory used during execution
  • Application: Name of the application that was executed
