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.
