Commands
Job Submission
Jobs are submitted using the qsub command. Generally it takes the form of
qsub $jobscript Where
$jobscript represents the script you are
submitting, which contains all the resource requirements, etc.
When a job is successfully submitted, the qsub
command will return a job designator, which is made up of a job number,
and the hostname of the scheduling system. For example:
$ qsub myscript
4875700.fslsched.fsl.byu.edu
This job number (4875700, in this example) can be used in other commands to check on a job's status, or remove a job before it is done running.
Sometimes qsub will return an error message stating that there
is a problem with your job. For example, if your job fails to request the
memory it needs, you might see this message:
Your job could not be submitted, due to the following error: -------------------------------------------------------------------------------- - Your job has failed to request memory, which is required of all jobs. For more information, see https://rc.byu.edu/memoryrequests.php -------------------------------------------------------------------------------- If you believe this is in error, feel free to open a support ticket via our website at https://rc.byu.edu/ticket/. Please include details about your resource request. -------------------------------------------------------------------------------- qsub: Your job has been administratively rejected by the queueing system. qsub: There may be a more detailed explanation prior to this notice.
System Status
The best command to use to check on the status of the system overall is
showq. It will list all jobs in the system, what state they
are in (running, eligible, blocked, etc.), the users who own them, etc. The
output is relatively long, so you may wish to redirect the output to a
screen paging tool, using something like this:
showq | less
You can generally use the arrow-keys, Page-Up/Page-Down, etc., to move
around within the "less" paging tool. When you are done, press
q to exit.
You can limit the output of showq based on username and other
features:
-
showq -u $username(Where$usernameis your username) - Will show only your jobs.
showq -r- Will show only the jobs that are running.
showq -i- Will show only eligible jobs
showq -b- Will show only blocked jobs.
Job Status
You can check on the status of a particular job using
checkjob $jobnumber, where
$jobnumber is the assigned job number of your job. This will
give you the state of the job (running, idle, etc.), the list of resources
requested, the assigned nodes, etc. If you want more detail, add the
-v option to the checkjob command.
Job Deletion
You can remove a job from the system by typing
qdel $jobnumber, where $jobnumber
is the assigned job number of your job. If the system can delete your job
successfully, there will be no output to this command. If an error occurs,
it will show on your screen.
