Make A Quoted Job Reservation
If the quote id is specified when making the reservation, the reservation will use the quoted amounts in calculating the amount to reserve and it will connect to the existing job entry.
Example 15. Make a reservation for the job that reflects the resource and quality preferences while specifying the quote id.
$ greserve -J PBS.1234.0 -p chemistry -u amy -m colony -P 16 -M 2048 -t 3600 -Q Premium -q 1 Successfully reserved 129946 credits for job PBS.1234.0 $ glsres Id Name Amount StartTime EndTime Job User Project Machine Accounts Description --- --------------- --------- ---------------------------- ---------------------------- ---- ------ ------------- ---------- ------------ ---------------- 1 PBS.1234.0 129946 2005-02-16 12:35:13 2005-02-16 13:35:13 3 amy chemistry colony 3
The reservation modifies the job entry to take on the new JobId and to change its stage from Quote to Reserve.
$ glsjob -j 1 Id JobId User Project Machine Queue QualityOfService Stage Charge Processors Nodes WallDuration StartTime EndTime Description --- --------------- ------ ------------- ---------- ------- ------------------------ ---------- --------- --------------- ------- ------------------ ------------- ---------- ---------------- 1 PBS.1234.0 amy chemistry colony Premium Reserve 16
As before, the reservation will decrease the balance by the amount reserved.

Gold has two accounts to choose from. Gold will debit allocations in the order of earliest expiring and most specific first. Specifically, precedence is considered in the following order of highest to lowest: hierarchical relation, expiration time, generality of the project, generality of the user, and generality of the machine. Here, Gold considers the account that is exclusively for amy to be more specific (and of hence of higher precedence) than the account that is exclusively for the colony machine. This ordering will ensure that allocations that will expire the soonest will be used up first and that accounts with more specific access restrictions will be used in favor of accounts that have more general access (for example - amy will use up an account just for amy before the she begins using a shared account).
