Queue information is available from the Queue Summary tab. You use this page to see whether a queue is functioning and how efficiently it is performing. From this page you can also view extensive details on any queue.
A queue in the N1GE environment is a means of defining a job's execution environment. This context includes features like:
job runtime limits (memory, stack, and CPU time)
control action methods (how to suspend and resume the job)
virtual job container (Solaris, Linux, or MS–Windows resource pools)
A queue instance is the portion of the queue that exists on a single host.
The information in this tab is presented in a table of queue instances, that is, the portion of the queue that runs on a particular host. Every queue instance that exists in the grid is listed.
The Queue Summary page show the following information:
Queue – The queue name. To see more detailed information on any queue, click the queue instance name.
Status – Describes whether this queue instance is running, suspended (manually or automatically in the case of an error), or waiting for a required resource to become available or a condition be met. If a queue instance is suspended or waiting, you may want to see more queue details.
Used Slots – The number of total slots this queue instance is consuming
Total Slots – The number of slots defined for this queue instance. Slots are the maximum number of jobs that a queue can run simultaneously.
You do not prioritize jobs using an N1GE queue. You define priorities using the extended policy system of the Sun N1 Grid Engine software. For information on job priorities, see the sge_priority(5) man page and Scheduler Policies for Job Prioritization in the Sun N1 Grid Engine 6 System (www.sun.com/blueprints/1005/819-4325.html).
For information on cluster queues, see the Monitoring and Controlling Queues section in the N1GE 6 User's Guide and the qmon man page. For more information on queue states, see the Queue Alerts page.
