Check job status : qstat , qstat -n1
Check full information of the job : qstat -f <job_id>
Delete the job from the queue : qdel <job_id>
Check the queue information : qstat -Q
Check jobs in queue : showq
Check queue parameters : qmgr -c ‘p s’

• Serial Queue : (Short queue) having 80 cores, walltime 24 hours and 128 GB RAM • Parallel Queue: (Long queue) having 140 cores, walltime 96 hours and 128 GB Ram • Gputest1 Queue: having 20 CPU cores with K40 card • SMP Queue having 64 cores and 1 TB RAM

With the approval of Supervisor/Dean the cluster account is created.

Storage is assigned initially as per below details: • Ph.D. 2 TB • PGDE 1 TB • M.Sc (2nd year) 200 GB • M.Sc (1st year) 100 GB

With the recommendation of Supervisor and further approval from the Dean SCIS, the storage limit may be extended with proper justification.
