Description

    This command displays the earliest possible start time of a job.  If the job already possesses a reservation, the start time of this reservation will be reported.  If no such reservation exists, this command will determine the earliest time a reservation would be created assuming this job was highest priority.   If this job does not have a reservation and it is not highest priority, the value of returned information may be limited.

Example

 > showstart job001

job Job001 requires 2 procs for 0:33:20
Earliest start is in          1:40:00 on Thu Jan  1 01:16:40
Earliest Completion is in     2:13:20 on Thu Jan  1 01:50:00
Best Partition: DEFAULT

Notes

    Since the information provided by this job is only highly accurate if the job is highest priority or if the job has a reservation, sites wishing to make decisions based on this information may want to consider using the RESERVATIONDEPTH parameter to increase the number of priority based reservations.  This can be set so that most, or even all idle jobs receive priority reservations and make the results of this command generally useful.  The only caution of this approach is that increasing the RESERVATIONDEPTH parameter more tightly constrains the decisions of the scheduler and may resulting in slightly lower system utilization (typically less than 8% reduction).
