Users are allowed to prolong their jobs in a limited number of cases.
To do this, use command qextend <full jobID> <additional_walltime>
(BUSTER)melounova@skirit:~$ qextend 8152779.meta-pbs.metacentrum.cz 01:00:00 The walltime of the job 8152779.meta-pbs.metacentrum.cz has been extended. Additional walltime: 01:00:00 New walltime: 02:00:00
- You must use full job ID to identify the job correctly (see Beginners_guide#Track_your_job).
- the time format can be either
- a single number - interpreted as seconds
- hh:mm:ss - interpreted as hours:minutes:seconds
To prevent abuse of the tool, there is a 30-day quota on how many times can the extend command be applied by a single user AND the total added time. Currently you can within the last 30 days
- extend your jobs 20-times
- use up to 1440 CPU-hours in total to prolong your jobs.
Job prolongations older than 30 days are "forgotten" and no longer occupy your quota.
To get current state of your fund, run qextend info:
(BUSTER)melounova@skirit:~$ qextend info melounova@META's info: 30-days counter limit: 20 Used counter limit: 2 Avail. counter limit: 18 30-days cputime fund: 1440:00:00 Used cputime fund: 01:00:01 Avail. cputime fund: 1438:59:59 Earliest rec. timeout: 2021-08-20 10:13:36.426429
- Counter limit is how many times you can prolong a job
- Cputime fund is the amount of cpu-time you can use to prolong a job
- Earliest rec. timeout indicates when the oldest one of your prolongations made during last 30 days will be forgotten
