This page lists some of the more frequently used Univa Grid Engine commands. It does not list all of the options for each command. The man command can be used to see the detailed description of any of these commands. For example, to see a detailed description of the qsub command, enter:
List of Commands:
|qsub||Submit a Job|
|qstat||Determine the Status of a Job|
|qhost||Display Node Information|
|qdel||Cancel a Job|
|qhold||Place a hold on a queued job to prevent it from running|
|qrls||Release a job held with qhold|
Use the qsub Command to Submit a Job
The qsub command is used to submit jobs to UGE. The syntax of the qsub command is:
qsub [-cwd] [-v SOME_VAR] [-o path] [-e path] [-M mail_address] [-m mail_options] [-l resources] script
- Directs UGE to run the job in the same directory from which you submitted it. Alternatively, you can specify this flag in the UGE command file for the job.
- -v SOME_VAR
- Passes environment variable SOME_VAR to the job. Alternatively, you can specify this flag in the UGE command file for the job.
- -o path
- Redirects stdout from the UGE script. The default is your home directory. Specify /dev/null to disgard UGE messages. Alternatively, you can specify this flag in the UGE command file for the job.
- -e path
- Redirects stderr from the UGE script. The default is your home directory. Specify /dev/null to disgard UGE error messages. Alternatively, you can specify this flag in the UGE command file for the job.
- -M mail_address
- where mail_address is user’s email address. It is always login_id@mail on Hoffman2.
- -m mail_options
- Specifies the circumstances under which mail is to be sent to the job owner defined by -M option. For example options “bea” mean mail is sent at the begining, end, and at abort time (if it happens) of the job. Option “n” means no mail will be sent.
- -l resources
- Specifies a list of resouces required for your job, for example memory and time per core:-l h_data=1024M,h_rt=24:00:00
- Either the UGE command file or the script that starts up your job.
The qsub command line switches and options can also be used as active comments or embedded directives in an UGE command file that you submit with the qsub command. Advantages of this approach are: you have a record of what options were used to run your job; you can easily resubmit jobs; and you can use one command file as the basis for creating other similar command files. For example, if the file myjob.cmd contains:
and the qsub command used to submit it is:
qsub -cwd -o path -M login_id@mail -m bea -l h_data=1024M,h_rt=24:00:00 myjob.cmd
then the same result could be achieved by adding the following lines to the myjob.cmd file before the /path/to/executable line:
#$ -o path
#$ -M login_id@mail
#$ -m bea
#$ -l h_data=1024M,h_rt=24:00:00
and submitting the myjob.cmd script with:
After submitting a job with qsub, UGE will respond with something like:
Your job 624556 (“myjob.cmd”) has been submitted
where 624556 is the job number assigned by UGE to your job.
The qstat command displays information about the jobs in the UGE queues, both running and waiting to run. The syntax of the qstat command is:
qstat [-f] [-j job_number] [-U login_id] [-u login_id]
- (qstat alone with no arguments)
- Displays a list of all running and waiting jobs.
- Displays summary information on each queue as well as the job list.
- -j job_number
- Displays the status of the job whose job number is job_number
- -U login_id
- Displays a list of running and waiting jobs for those queues which login_id can access.
- -u login_id
- Displays a list of login_id ‘s running and waiting jobs.
The qhost command displays information about compute nodes: their architectures, number of processors, load, etc. The syntax of the qhost command is:
qhost [-j] [-q]
- (qhost alone with no arguments)
- Displays a table of information about the compute nodes.
- Adds information about the specific jobs that are running on each compute node.
- Shows the queues each compute node accepts.
The qdel command is used to cancel a job either while it is waiting to execute or while it is running. The syntax of the qdel command is:
Jobs in the “dr” state (disabled running) cannot be canceled by the job owner. They will be canceled by a system administrator.
