Dispatching

It is really no longer necessary to discuss queues in the traditional sense. In the past, we would create queues based on pools of hardware resources. If a user wanted to utilize a particular hardware resource, he or she would request the appropriate queue. Most times, however, what the user wants and what is best for the user or what is best for all users are not necessarily the same. Allowing individuals to dictate where their jobs will run will inevitably lead to throughput problems since it would be unreasonable to expect the users to understand the complete state and behavior of the scheduler.

Below is a general description of how jobs make their way through the queue. Please see Scheduling and Dispatch Policy for more information.

When a user submits a job to a specific partiton, the scheduler determines if the requested hardware/time requirements of the job (see Using Features) match up with the resources the partition provides. If it does, the job is executed if there are available resources. If there are no available resources, the job will be held until the next scheduler iteration, to see if resources have become available.

“Available resources” include processors and memory. Processors generally match up to the number of slots in a given queue while memory is defined as a complex value which may not be so obvious to query. If your job is waiting in the qw state, it is likely that either the slots requested or the memory requested are beyond what the system can provide at that particular point in time.
