SGE Commands
What are some basic SGE commands?


Commonly-Used SGE Commands
qsub	Submit a Job
qstat	Determine the Status of a Job
qstat -t -ext -s r -u (user)	Show start time and cpu time for running jobs
qdel	Cancel a job
qhold	Place a hold on a queued job to prevent it from running
qrls	Release a job held with qhold
qhost	Display Node Information
qmon	An X-Windows interface to SGE commands


qsub
The ‘qsub’ command submits a job to the SGE queueing system.

For example, to submit simple.sh script, run:

$ qsub simple.sh
A message will be displayed with the job ID and job name:

Your job 96606 (“simple.sh”) has been submitted
Qsub assigns the job to the workstation with the most resources available. When finished, qsub produces 2 files in my home directory (by default): an error file and an output file, e.g.:

simple.sh.e96606
simple.sh.o96606
... where ‘e’ indicates ‘error’ and ‘o’ indicates ‘output’. The number in the file name is the job submission number.

qload
The ‘qload’ command displays SGE job utilization.

It prints a summary of everyone’s submitted jobs, and lists your running jobs with system CPU/memory information.
qstat
The ‘qstat’ command displays detailed SGE job information. It has many useful options. For a complete list, run ‘man qstat’ (type ‘q’ to quit).

To list your jobs, use the ‘qstat’ command without any options.

To list everyone’s jobs, use the ‘qstats’ command (which is a shortcut for ‘qstat -f -ne -u \*’). To view the output one page at a time, include the ‘less’ command (type ‘q’ to quit):

$ qstats | less
The -j option prints detailed information for a specific job. This is useful to identify why a job remains queued, or is in E(rror) state. The syntax is qstat -j <JobID>, for example

$ qstat -j 193013
qdel
The ‘qdel’ command deletes a job from the queue.

To delete all of your jobs:

$ qdel -u $USER
Note

$USER will be interpreted by the shell as your unix account name. You may use $USER in shell commands and shell scripts instead of your unix account name.

To delete a single job:

$ qdel 6033
To delete a specific range of jobs, see for loop iteration.
