Kill Jobs #

To kill a specific job, use:

qdel <jobid>

If the node, where the job is running, is non-responsive, you can force the scheduler to remove the job by using:

qdel -f <jobid>

Note that this command can take a long time to complete (up to a couple of minutes) if the node is non-responsive.

To kill all of your jobs, use:

qdel -u $USER

Technical details: If the job was submitted with SGE option -notify, then the scheduler send signal SIGUSR2 twice to the job notifying that it is about to be terminated. The second signal is sent momentarily after the first. This is also the case when the job exhausts its maximum runtime. The job process can choose to capture this signal to perform a clean-up task before exiting. If the job process is still running 60 seconds after these notification signals, then it will be terminated with signal SIGKILL, which cannot be caught. If -notify was not specified, then only SIGKILL is signaled.
