10.11.2 Examining the Status of a Job

Once a job is submitted, you can use the bjobs command to track the job's progress. The bjobs command reports the status of a job submitted to LSF. By default, bjobs lists only the user's jobs that have not finished or exited.

The following are examples of bjobs command usage, and show the output it produces on an HP XC system. For more information about the bjobs command and its output, see the LSF manpages.

Example 10-5provides abbreviated output of the bjobs command.

As shown in the previous output, the bjobs command returns information that includes the job id, user name, job status, queue name, submitting host, executing host, job name, and submit time. In this example, the output shows that job /bin/bash was submitted from node n16 and launched on the execution host (lsfhost.localdomain).

Example 10-6provides extended output of the bjobs command.
