Managing Jobs
Listing running and queued jobs
The squeue
command will list all jobs scheduled in the cluster. We have also written wrappers for squeue
on Oscar that you may find more convenient:
Viewing estimated time until completion for pending jobs
This command will list all of your pending jobs and the estimated time until completion.
Canceling jobs
View details about completed jobs
The sacct
command will list all of your running, queued and completed jobs since midnight of the previous day. To pick an earlier start date, specify it with the -S
option:
To find out more information about a specific job, such as its exit status or the amount of runtime or memory it used, specify the -l
("long" format) and -j
options with the job ID:
The myjobinfo
command uses the sacct
command to display "Elapsed Time", "Requested Memory" and "Maximum Memory used on any one Node" for your jobs. This can be used to optimize the requested time and memory to have the job started as early as possible. Make sure you request a conservative amount based on how much was used.
ReqMem
shows the requested memory: A c
at the end of number represents Memory Per CPU, a n
represents Memory Per Node. MaxRSS
is the maximum memory used on any one node. Note that memory specified to sbatch using --mem
is Per Node.
