PBS command

PBS is an open source job management system, running in this environment, users do not need to specify which nodes the program runs on, and the hardware resources needed by the program are managed and allocated by PBS.

PBS command

PBS provides four commands for job management.

(1) qsub command-used to submit job scripts

Command format:

Qsub [- a date_time] [- c interval] [- C directive_prefix] [- e path] [- I] [- j join]

[- k keep] [- l resource_list] [- m mail_options] [- M user_list] [- N name]

[- o path] [- p priority] [- Q destination] [- r c] [- S path_list] [- u user_list]

[- v variable_list] [- V] [- W additional_attributes] [- z] [script]

Parameter description: because the options used are generally submitted in the pbs script, see the PBS script option for details.

Example: # qsub aaa.pbs # submit a job, the system will generate an assignment number, aaa.pbs this file to store the content you want to operate or execute, script!

(2) qstat command-used to query job status information

Command format: qstat [- f] [- a] [- I] [- n] [- s] [- R] [- Q] [- Q] [- B] [- u]

Parameter description:

-f jobid lists the information for the specified job

-a list all jobs in the system

-I list jobs that are not running

-n lists the nodes assigned to this job

-s lists the suggestions provided by the queue administrator and scheduler

The-Q operator is destination id, indicating that the queue status is requested

-Q lists the queue status and displays it in alternative form

-au userid lists all jobs for the specified user

-B list PBS Server information

-r lists all running jobs

-Qf queue lists the information of the specified queue

-u if the operator is a job number, its status is listed.

If the operator is destination id, lists the status of jobs running on it that belong to users in user_list.

Qmgr-c "set queue batch enabled=true"

Qmgr-c "set queue batch resources_default.nodes=1"

Qmgr-c "set queue batch resources_default.walltime=3600"
