Monitoring and Controlling Queue Instances

The Queue Instances tab provides a quick overview of all queue instances that are associated with the selected cluster queue. The Queue Instance tab also provides the means to suspend, resume, disable, and enable queue instances.

Click a cluster queue name to select the queue instance.

Click Suspend, Resume, Disable, or Enable to execute the corresponding operation on queue instances that you select. The suspend/resume and disable/enable operations require notification of the corresponding sge_execd. If notification is not possible, for example, because the host is not reachable, you can force an sge_qmaster internal status change by clicking Force.

The suspend/resume and disable/enable operations require queue owner permission, manager permission, or operator permission. See Managers, Operators, and Owners.

Suspended queue instances are closed for further jobs. The jobs already running in suspended queue instances are also suspended, as described in Monitoring and Controlling Jobs With QMON. The queue instance and its jobs are unsuspended as soon as the queue instance is resumed.

If a job in a suspended queue instance was suspended explicitly, the job is not resumed when the queue instance is resumed. The job must be resumed explicitly.

Disabled queue instances are closed. However, the jobs executing in those queue instances are allowed to continue. The disabling of a queue instance is commonly used to clear a queue instance. After the queue instance is enabled, it is eligible to run jobs again. No action on currently running jobs is performed.

Queue Instance Status

Each row in the queue instances table represents one queue instance. For each queue instance, the table lists the following information:

• Queue – Name of the queue instance

• qtype – Type of queue instance, which can be B (batch), I (interactive), or P (parallel)

• used/total – Number of used job slots and the total number of job slots

• load_avg – Load average of the queue instance host

• arch – Architecture of the queue instance host

• states – States of the queue instance

See Cluster Queue Status for a list of queue states. See the qstat(1) man page for complete information about queue instances and their states.
