Filtering a Job Script

You can write a program to filter a job script when the job is submitted. This program can, for example, modify defaults or perform site specific verification of parameters. To invoke the program, specify the following keyword in your configuration file:

SUBMIT_FILTER = myprog

where myprog is called with the job file as the standard input. The standard output is submitted to LoadLeveler. If the program returns with a non-zero exit code, the job submission is cancelled.

The following environment variables are set when the program is invoked:

LOADL_ACTIVE

LoadLeveler version

LOADL_STEP_COMMAND

Job command file name

LOADL_STEP_ID

The job identifier, generated by LoadLeveler

LOADL_STEP_OWNER

The owner (UNIX user name) of the job
