Using queues

The system is set up so that above all queues there is a RouteQ routing queue that ensures that jobs without a defined queue fall into the right job queue, based on the required computation time. If jobs do not ask for compute time in the job description, they are automatically assigned 48 hours and sent to the cpu queue.

An example of executing jobs without defining the execution time, but with a defined queue



Backfilling

In order to further encourage users to define the execution time, the Backfilling option is enabled on the system, i.e. jobs with a shorter execution time are allowed to skip jobs with a longer execution time, if it is always satisfied that the execution of a shorter job will not affect the start of the one with a longer execution.
