Managing Jobs

You can use the buttons at the right of the dialog box to manage selected jobs in the following ways:

• Suspend

• Resume (unsuspend)

• Delete

• Hold back

• Release

• Reprioritize

• Reschedule

• Modify with qalter

Only the job owner or grid engine managers and operators can suspend and resume jobs, delete jobs, hold back jobs, modify job priority, and modify jobs. See Managers, Operators, and Owners. Only running jobs can be suspended or resumed. Only pending jobs can be rescheduled, held back and modified, in priority as well as in other attributes.

Suspension of a job sends the signal SIGSTOP to the process group of the job with the UNIX kill command. SIGSTOP halts the job and no longer consumes CPU time. Resumption of the job sends the signal SIGCONT, thereby unsuspending the job. See the kill(1) man page for your system for more information on signalling processes.

You can force suspending, resuming, and deleting jobs. In other words, you can register these actions with sge_qmaster without notifying the sge_execd that controls the jobs. Forcing is useful when the corresponding sge_execd is unreachable, for example, due to network problems. Select the Force option for this purpose.

Click Reschedule to reschedule a currently running job.
