Used only with job dependency scheduling.
If set to 1, whenever dependency conditions use a job name that belongs to multiple jobs, LSF evaluates only the most recently submitted job.
Otherwise, all the jobs with the specified name must satisfy the dependency condition.
Running jobs are not affected when JOB_DEP_LAST_SUB is changed. To reevaluate job dependencies after changing JOB_DEP_LAST_SUB, run badmin mbdrestart.
Set to 1 at time of installation for the DEFAULT and PARALLEL configuration templates. If otherwise undefined, then 0 (turned off).
