Job queues represent different job scheduling and control policies. All jobs submitted to the same queue share the same scheduling and control policy. Each job queue can use a configured subset of server hosts in the cluster; the default is to use all server hosts.
System administrators can configure job queues to control resource access by different users and types of application. Users select the job queue that best fits each job.
The default queue is normally suitable to run most jobs, but the default queue may assign your jobs a very low priority, or restrict execution conditions to minimize interference with other jobs. If automatic queue selection is not satisfactory, choose the most suitable queue for each job.
The factors affecting which queue to choose are user access restrictions, size of job, resource limits of the queue, scheduling priority of the queue, active time windows of the queue, hosts used by the queue, scheduling load conditions, and the queue description displayed by the bqueues -l command.
