JOB_PREPROC_TIMEOUT

Description

Specify a timeout in minutes for job pre-execution processing. The specified timeout must be an integer greater than zero. If the job's pre-execution processing takes longer than the timeout, LSF kills the job's pre-execution processes, kills the job with a pre-defined exit value of 98, and then re-queues the job to the head of the queue. However, if the number of pre-execution retries has reached the limit, LSF suspends the job with PSUSP status instead of re-queuing it.

JOB_PREPROC_TIMEOUT defined in an application profile in lsb.applications overrides the value in lsb.params. JOB_PREPROC_TIMEOUT cannot be defined in the user environment.

On UNIX and Linux, sbatchd kills the entire process group of the job's pre-execution processes.

On Windows, only the parent process of the pre-execution command is killed when the timeout expires, the child processes of the pre-execution command are not killed.

In the MultiCluster job forwarding model, JOB_PREPROC_TIMEOUT and the number of pre-execution retries defined in the receiving cluster apply to the job. When the number of attempts reaches the limit, the job returns to submission cluster and is rescheduled.

In the MultiCluster job lease model, JOB_PREPROC_TIMEOUT and the number of pre-execution retries defined in the submission cluster apply to jobs running on remote leased hosts, as if they were running on local hosts.

Default

Not defined. Pre-execution processing does not time out. However, when running host-based pre-execution processing, you cannot use the infinite value or it may fail. You must configure a reasonable value.
