LSF Version 7.3 - Platform LSF Configuration Reference

Feature: Pre-execution and post-execution
processing
The pre- and post-execution processing feature provides a way to run commands on the
execution host prior to and after completion of LSF jobs. Use pre-execution commands to set
up an execution host with the required directories, files, software licenses, environment, and
user permissions. Use post-execution commands to define post-job processing such as
cleaning up job files or transferring job output.

About pre- and post-execution processing
You can use the pre- and post-execution processing feature to run commands before a batch
job starts or after it finishes. Typical uses of this feature include the following:
•
Reserving resources such as tape drives and other devices not directly configurable in LSF
•
Making job-starting decisions in addition to those directly supported by LSF
•
Creating and deleting scratch directories for a job
•
Customizing scheduling based on the exit code of a pre-execution command
•
Checking availability of software licenses
•
Assigning jobs to run on specific processors on SMP machines
•
Transferring data files needed for job execution
•
Modifying system configuration files before and after job execution
•
Using a post-execution command to clean up a state left by the pre-execution command
or the job
Pre-execution commands can be defined at the queue, application, and job levels. Post-
execution commands can be defined at the queue and application levels.
