LSB_CHUNK_RUSAGE=y
Applies only to chunk jobs. When set, sbatchd contacts PIM to retrieve resource usage information to enforce resource usage limits on chunk jobs.
By default, resource usage limits are not enforced for chunk jobs because chunk jobs are typically too short to allow LSF to collect resource usage.
If LSB_CHUNK_RUSAGE=Y is defined, limits may not be enforced for chunk jobs that take less than a minute to run.
Not defined. No resource usage is collected for chunk jobs.
