man qdel

Qmgr is the main application used to manage PBS Torque. This is used to create queues, modify queue settings, and print the configuration. Please review the man page or the link for information about this command. Any changes implemented using this command are permanent and are written to the running configuration file.

user@polyp1:~$ qmgr -c "print queue batch"
user@polyp1:~$ qmgr -c "p q batch"
#
# Create queues and set their attributes.
#
#
# Create and define queue batch
#
create queue batch
set queue batch queue_type = Execution
set queue batch resources_max.walltime = 01:00:00

qalter - alter a non-running queued job.

qalter <job number> <change to the queued job>

The line below changes the node specification for job id 1398668. Original job submission did not specify a node, this specifies a node with the same ppn (processors per node)

                      qalter 1398668 -l nodes=polyp14:ppn=1

qdel - Delete a batch job

qdel <job id>
                   qdel 1186460

qhold Place non-running job in a state so it will not run. If the job is running, and checkpointing is not enabled the job will terminate.

qmove Move a submitted job to another queue.

qrun Command used to take a non-running job and make it run. When I use this, I look at running jobs and then use the qalter command to specify the node I want the job to run on (based on available resources).

qstart The qstart command directs the torque server process batch jobs. This command can enable the entire server or a queue.

qstop The qstop command directs the torque server to stop processing batch jobs. Can be use to disable the server or just a queue.

qenable The qenable command directs the destination (server / queue) to accept jobs for processing.

qdisable The qdisable command directs the destination (server / queue) to stop accepting jobs for processing.

pbsnodes This command can be use to enable and disable nodes in the queuing system.

manager@polyp1:~$ pbsnodes -l
polyp5               down
polyp14              offline
polyp15              offline
polyp30              offline

Take a node offline:
manager@polyp1:~$ pbsnodes -o polyp15

Put a node back online:
manager@polyp1:~$ pbsnodes -c polyp15

Current Normal Output from pbsnodes -l:
manager@polyp1:~$ pbsnodes -l
polyp5               down,offline
polyp30              offline
