## Resources Allocation Policy
# Resources Allocation Policy
### Job queue policies
## Job queue policies
The resources are allocated to the job in a fair-share fashion, subject to constraints set by the queue and resources available to the Project. The Fair-share at Anselm ensures that individual users may consume approximately equal amount of resources per week. Detailed information in the [Job scheduling](job-priority/) section. The resources are accessible via several queues for queueing the jobs. The queues provide prioritized and exclusive access to the computational resources. Following table provides the queue partitioning overview:

* **qnvidia**, qmic, qfat, the Dedicated queues: The queue qnvidia is dedicated to access the Nvidia accelerated nodes, the qmic to access MIC nodes and qfat the Fat nodes. It is required that active project with nonzero remaining resources is specified to enter these queues. 23 nvidia, 4 mic and 2 fat nodes are included. Full nodes, 16 cores per node are allocated. The queues run with very high priority, the jobs will be scheduled before the jobs coming from the qexp queue. An PI needs explicitly ask [support](https://support.it4i.cz/rt/) for authorization to enter the dedicated queues for all users associated to her/his Project.

* **qfree**, The Free resource queue: The queue qfree is intended for utilization of free resources, after a Project exhausted all its allocated computational resources (Does not apply to DD projects by default. DD projects have to request for persmission on qfree after exhaustion of computational resources.). It is required that active project is specified to enter the queue, however no remaining resources are required. Consumed resources will be accounted to the Project. Only 178 nodes without accelerator may be accessed from this queue. Full nodes, 16 cores per node are allocated. The queue runs with very low priority and no special authorization is required to use it. The maximum runtime in qfree is 12 hours.

The job wall clock time defaults to **half the maximum time**, see table above. Longer wall time limits can be [set manually, see examples](job-submission-and-execution/).
