Configuring Job Control Actions
Administering Platform LSF

Syntax
TERMINATE_WHEN = [LOAD] [PREEMPT] [WINDOW]
Example
The following defines a night queue that will kill jobs if the run window closes.
Begin Queue
NAME = night
RUN_WINDOW = 20:00-08:00
TERMINATE_WHEN = WINDOW
JOB_CONTROLS = TERMINATE[ kill -KILL $LSB_JOBPIDS;
echo "job $LSB_JOBID killed by queue run window" |
mail $USER ]
End Queue
LSB_SIGSTOP parameter (lsf.conf)
Use LSB_SIGSTOP to configure the SIGSTOP signal sent by the default SUSPEND
action.
If LSB_SIGSTOP is set to anything other than SIGSTOP, the SIGTSTP signal that is
normally sent by the SUSPEND action is not sent. For example, if
LSB_SIGSTOP=SIGKILL, the three default signals sent by the TERMINATE action
(SIGINT, SIGTERM, and SIGKILL) are sent 10 seconds apart.
See the Platform LSF Reference for information about the
lsf.conf file.
Avoiding signal and action deadlock
Do not configure a job control to contain the signal or command that is the same as the
action associated with that job control. This will cause a deadlock between the signal and
the action.
For example, the
bkill command uses the TERMINATE action, so a deadlock results
when the TERMINATE action itself contains the
bkill command.
Any of the following job control specifications will cause a deadlock:
◆ JOB_CONTROLS=TERMINATE[bkill]
◆ JOB_CONTROLS=TERMINATE[brequeue]
◆ JOB_CONTROLS=RESUME[bresume]
◆ JOB_CONTROLS=SUSPEND[bstop]
