Make A Job Reservation
When a job starts, the resource management system creates a reservation (or pending charge) against the appropriate allocations based on the estimated wallclock limit specified for the job (see Making a Job Reservation).
Example 10. Make a reservation for the job.
$ greserve -J PBS.1234.0 -p chemistry -u amy -m colony -P 16 -t 3600 Successfully reserved 57600 credits for job PBS.1234.0 $ glsres Id Account Amount Name Job User Project Machine EndTime Type Description --- ---------- --------- --------------- ----- ------ ------------- ---------- --------------------------------- ---------- ---------------- 1 2 57600 PBS.1234.0 1 amy chemistry colony 2005-08-03 15:29:30-07 Normal
This reservation will decrease the balance by the amount reserved.
$ gbalance -p chemistry —total —quiet 359942400
Although the allocation has not changed.
$ glsalloc -p chemistry Id Account StartTime EndTime Amount CreditLimit Deposited Description --- ---------- --------------- --------------- ------------- ---------------- ------------- ---------------- 2 2 2005-01-01 2006-01-01 360000000 0 360000000
This is best illustrated by the detailed balance listing:
$ gbalance -p chemistry Id Name Amount Reserved Balance CreditLimit Available --- ------------- ------------- ------------ ------------- ---------------- ------------- 2 chemistry 360000000 57600 359942400 0 359942400
