Configuring Job Control Actions Configuring Job Control Actions Several situations may require overriding or augmenting the default actions for job control. For example: ◆ Notifying users when their jobs are suspended, resumed, or terminated ◆ An application holds resources (for example, licenses) that are not freed by suspending the job. The administrator can set up an action to be performed that causes the license to be released before the job is suspended and re-acquired when the job is resumed. ◆ The administrator wants the job checkpointed before being: ❖ Suspended when a run window closes ❖ Killed when the RUNLIMIT is reached ◆ A distributed parallel application must receive a catchable signal when the job is suspended, resumed or terminated to propagate the signal to remote processes. To override the default actions for the SUSPEND, RESUME, and TERMINATE job controls, specify the JOB_CONTROLS parameter in the queue definition in lsb.queues. JOB_CONTROLS parameter (lsb.queues) signal CHKPNT command The JOB_CONTROLS parameter has the following format: Begin Queue ... JOB_CONTROLS = SUSPEND[signal | CHKPNT | command] \ RESUME[signal | command] \ TERMINATE[signal | CHKPNT | command] ... End Queue When LSF needs to suspend, resume, or terminate a job, it invokes one of the following actions as specified by SUSPEND, RESUME, and TERMINATE. A UNIX signal name (for example, SIGTSTP or SIGTERM). The specified signal is sent to the job. The same set of signals is not supported on all UNIX systems. To display a list of the symbolic names of the signals (without the SIG prefix) supported on your system, use the kill -l command. Checkpoint the job. Only valid for SUSPEND and TERMINATE actions. ◆ If the SUSPEND action is CHKPNT, the job is checkpointed and then stopped by sending the SIGSTOP signal to the job automatically. ◆ If the TERMINATE action is CHKPNT, then the job is checkpointed and killed automatically. A /bin/sh command line. Do not quote the command line inside an action definition. See the Platform LSF Reference for information about the lsb.queues file. 392 Administering Platform LSF
Chapter 31 Configuring Job Controls Using a command as a job control action TERMINATE job actions The following apply to a job control action that is a command: ◆ ◆ ◆ ◆ ◆ The command line for the action is run with /bin/sh -c so you can use shell features in the command. The command is run as the user of the job. All environment variables set for the job are also set for the command action. The following additional environment variables are set: ❖ LSB_JOBPGIDS—a list of current process group IDs of the job ❖ LSB_JOBPIDS—a list of current process IDs of the job For the SUSPEND action command, the following environment variable is also set: LSB_SUSP_REASONS—an integer representing a bitmap of suspending reasons as defined in lsbatch.h. The suspending reason can allow the command to take different actions based on the reason for suspending the job. The standard input, output, and error of the command are redirected to the NULL device, so you cannot tell directly whether the command runs correctly. The default null device on UNIX is /dev/null. You should make sure the command line is correct. If you want to see the output from the command line for testing purposes, redirect the output to a file inside the command line. Use caution when configuring TERMINATE job actions that do more than just kill a job. For example, resource usage limits that terminate jobs change the job state to SSUSP while LSF waits for the job to end. If the job is not killed by the TERMINATE action, it remains suspended indefinitely. TERMINATE_WHEN parameter (lsb.queues) Syntax In certain situations you may want to terminate the job instead of calling the default SUSPEND action. For example, you may want to kill jobs if the run window of the queue is closed. Use the TERMINATE_WHEN parameter to configure the queue to invoke the TERMINATE action instead of SUSPEND. See the Platform LSF Reference for information about the lsb.queues file and the TERMINATE_WHEN parameter. TERMINATE_WHEN = [LOAD] [PREEMPT] [WINDOW] Administering Platform LSF 393
