Overview
General usage
Special usage notes
- Change the total cpu time allotted to a job via
qalter -l cput=[new_cput] [job_id]
where [new_cput] is the desired amount of cpu time and [job_id] is the job's ID number. Multiple jobs can be changed simultaneously by using `seq [min_job_id] [max_job_id]` in the place of job_id. This will change all jobs [min_job_id] through [max_job_id]. Lowering the cpu time requirement of a job can decrease its wait time in the queue, as the scheduler is more likely to be able to use if for backfilling. On the other hand, increasing the cpu time requirement can be used to ensure that a job is able to finish properly (and can be done even while the job is running), but requires root permission.
- Move a queued (i.e., waiting) job to a different queue via
qmove [destination] [job_id]
where [destination] is the new queue (either 'fast' or 'default' for our system) and [job_id] is the job ID.
