For queues that consist of all nodes containing a GPU, and are split out into a QUEUE-GPU queue, the policy is to set the ngpus resource to 1 if not explicitly set. For other queues that contain GPU nodes the policy has been set by the queue owner to either request a GPU by default or not.
Guidelines for selecting a queue
Guidelines for selecting a queue
It may not always be obvious, particularly if you are a member of an investor group, which is the best queue to submit a job to. As a guideline, if you are in an investor group and there are enough free slots in your queue for your job(s) then you should use the investor queue. If you are not in an investor group, or there are not enough free slots in your investor queue, you should submit parallel jobs to the UI queue. If not submitting to an investor queue, and if your jobs are serial jobs, they should generally be submitted to the all.q queue. Unless you have a small number of jobs, and/or can not risk them getting evicted, then use the UI queue.
