The qstat -Q shows a summary of all Artemis queues. Not all of these can be submitted to directly; some are reserved for users with strategic allocations and many are only accessible via defaultQ 173670637. Your job will usually be routed to other “internal” queues after submission depending on the size of your job.
...
An “express” queue for small jobs. These jobs will typically start quickly, but will increase your fair share weight 5 times faster than small, normal or large jobs in defaultQ 173670637. This queue is useful for quickly testing your jobs before submitting a longer job to defaultQ 173670637.
scavenger
A low priority queue that runs jobs on idle resources in strategic allocations. If your job completes it will be “free”, in that it will not increase your Project’s fair share value. The downside is there is no assurance that your job will finish. If a strategic allocation user submits jobs to their allocation and requires resources that a scavenger job is using, the scavenger job will be suspended. If the scavenger job cannot be resumed within half the requested walltime of the scavenger job, it will be terminated and all unsaved progress will be lost.

This queue is for running interactive (command line) sessions on a compute node. Interactive sessions can only be requested using the qsub –I command from the command line. You cannot request an interactive session from a job script. This queue attracts a fair share weighting 10 times higher than standard memory jobs in defaultQ 173670637. An example command to submit a job to the interactive queue is:
...
This queue is for performing computations with programs that use GPUs (Graphical Processing Units). To use GPUs, request gpus in the select directive, and submit your job to defaultQ 173670637:

The fair share weighting of this queue is 5 times higher than defaultQ. |
Strategic Allocations
Some researchers have access to dedicated compute resources on Artemis. Only members of the Lead Chief Investigator’s projects may submit jobs to these queues. Scavenger jobs will run on idle resources in these queues.

Users with strategic allocations are also free to request their jobs be run in all other publically accessible queues in addition to their strategic allocation173670637. |
Condominiums
Some researchers have access to condominium compute resources. Only projects nominated by the relevant condominium owner may submit jobs to these queues.
