 [[https://hpcwiki.uark.edu/doku.php?id=slurm_queues/ |Job queues]] determine which specific resources a user can request, both in terms of run time and specific hardware. AHPCC requires that users select the appropriate queue for their job submissions at all times. Jobs that are incorrectly submitted to queues that don't match the application will be killed by administrators. Submitting to alternate queues just because the appropriate queue is busy is not allowed! [[https://hpcwiki.uark.edu/doku.php?id=slurm_queues/ |Job queues]] determine which specific resources a user can request, both in terms of run time and specific hardware.

-  * **Cloud Queue** - If you are using a serial (non-parallel) task, submit to this queue as it is designated for this purpose specifically.+  * **Cloud Queue** - If you are using a serial (non-parallel) job **OR** if you need less than 32 cores for your job, submit to this queue as it is designated for this purpose specifically. 
 +  * **Comp Queues** - These queues require that you request and utilize the full compliment of cores available on the resource.
   * **Himem Queues** - Don't submit jobs to this queue unless you truly need greater than 192GB of memory. If unsure, first test on a Comp queue to see if your task runs out of memory before migrating to the Himem queues.   * **Himem Queues** - Don't submit jobs to this queue unless you truly need greater than 192GB of memory.

   * **GPU Queues** - Do not submit to the GPU queues unless you are certain that your application/task can effectively utilize the GPU hardware. AHPCC staff can help you evaluate your code if needed.   * **GPU Queues** - Do not submit to the GPU queues unless you are certain that your application/task can effectively utilize the GPU hardware.

   * **Condo Queues** - Users should only submit jobs to the actual condo queue if your research group has actually purchased resources for this queue! If you have condo resources, the AHPCC staff will inform you as to how to submit jobs to your specific resources. Non-owners can still utilize these resources for short periods of time by submitting to the Pcon06 queue. AHPCC has an agreement with Condo purchasers that non-owners can utilize these resources for up to 6 hours at a time, and with low priority to the queue.   * **Condo Queues** - Users should only submit jobs to the actual condo queue if your research group has actually purchased resources for this queue!

 +  * **Trestles Queues** - Kind of a "catch-all" queue...the nodes are almost 12 years old and only half as fast as the other offerings, but there are a LOT of them, and there are usually at least a few available at any time. We also offer a 288 hour walltime on these which may be of interest to some.
