LSB_TIME_RESERVE_NUMJOBS

Syntax

LSB_TIME_RESERVE_NUMJOBS=maximum_reservation_jobs

Description

Enables time-based slot reservation. The value must be positive integer.

LSB_TIME_RESERVE_NUMJOBS controls maximum number of jobs using time-based slot reservation. For example, if LSB_TIME_RESERVE_NUMJOBS=4, only the top 4 jobs get their future allocation information.

Use LSB_TIME_RESERVE_NUMJOBS=1 to allow only the highest priority job to get accurate start time prediction.

Valid values

As a best practice, set the value to 3 or 4. Larger values are not as useful because after the first pending job starts, the estimated start time of remaining jobs may be changed.
