* **qexp**, the Express queue: This queue is dedicated for testing and running very small jobs. It is not required to specify a project to enter the qexp. There are 2 nodes always reserved for this queue (w/o accelerator), maximum 8 nodes are available via the qexp for a particular user, from a pool of nodes containing Nvidia accelerated nodes (cn181-203), MIC accelerated nodes (cn204-207) and Fat nodes with 512GB RAM (cn208-209). This enables to test and tune also accelerated code or code with higher RAM requirements. The nodes may be allocated on per core basis. No special authorization is required to use it. The maximum runtime in qexp is 1 hour.
* **qprod**, the Production queue: This queue is intended for normal production runs. It is required that active project with nonzero remaining resources is specified to enter the qprod. All nodes may be accessed via the qprod queue, except the reserved ones. 178 nodes without accelerator are included. Full nodes, 16 cores per node are allocated. The queue runs with medium priority and no special authorization is required to use it. The maximum runtime in qprod is 48 hours.
* **qlong**, the Long queue: This queue is intended for long production runs. It is required that active project with nonzero remaining resources is specified to enter the qlong. Only 60 nodes without acceleration may be accessed via the qlong queue. Full nodes, 16 cores per node are allocated. The queue runs with medium priority and no special authorization is required to use it. The maximum runtime in qlong is 144 hours (three times of the standard qprod time - 3 x 48 h).
* **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.

However, it allows for utilization of free resources, once a Project exhausted all its allocated computational resources.

* **qfat**, the UV2000 queue. This queue is dedicated to access the fat SGI UV2000 SMP machine. The machine (uv1) has 112 Intel IvyBridge cores at 3.3GHz and 3.25TB RAM (8 cores and 128GB RAM are dedicated for system). An PI needs explicitly ask support for authorization to enter the queue for all users associated to her/his Project.

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.

The queue runs with very low priority and no special authorization is required to use it. The maximum runtime in qfree is 12 hours.
* **qviz**, the Visualization queue: Intended for pre-/post-processing using OpenGL accelerated graphics. Currently when accessing the node, each user gets 4 cores of a CPU allocated, thus approximately 73 GB of RAM and 1/7 of the GPU capacity (default "chunk"). If more GPU power or RAM is required, it is recommended to allocate more chunks (with 4 cores each) up to one whole node per user, so that all 28 cores, 512 GB RAM and whole GPU is exclusive. This is currently also the maximum allowed allocation per one user. One hour of work is allocated by default, the user may ask for 2 hours maximum.
* **qmic**, the queue qmic to access MIC nodes. It is required that active project with specified to enter these queues. 864 mic are included.
!!! note
To access node with Xeon Phi co-processor user needs to specify that in [job submission select statement](job-submission-and-execution/).
