DCG queues are the queues that users see in client applications when they choose to submit jobs to a cluster via DCG. Queue names can match the names of queues or queueing mechanisms defined on the HPC resource. The important thing to remember is that each DCG queue name must be unique.
There are two ways to define DCG queues: you can either import a list of HPC queues and define an DCG queue for each HPC queue, or you can manually add a DCG queue and assign an HPC queue to it.
To be able to add queues to a cluster configuration, you must have 'Create queue' permission on the cluster configuration.
