**The qfree queue is not free of charge**. [Normal accounting](#resources-accounting-policy) applies. However, it allows for utilization of free resources, once a project has exhausted all its allocated computational resources. This does not apply to Director's Discretion projects (DD projects) by default. Usage of qfree after exhaustion of DD projects' computational resources is allowed after request for this queue.

***qprod**, the Production queue: This queue is intended for normal production runs. It is required that an 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 accelerators 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 an 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 that of the standard qprod time - 3 x 48 h).
***qnvidia**, qmic, qfat, the Dedicated queues: The queue qnvidia is dedicated to accessing the Nvidia accelerated nodes, the qmic to accessing MIC nodes and qfat the Fat nodes. It is required that an 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 to explicitly ask [support](https://support.it4i.cz/rt/) for authorization to enter the dedicated queues for all users associated with her/his project.
***qfree**, The Free resource queue: The queue qfree is intended for utilization of free resources, after a project has exhausted all of its allocated computational resources (Does not apply to DD projects by default; DD projects have to request persmission to use qfree after exhaustion of computational resources). It is required that an 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 accelerators 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.
***qfree**, The Free resource queue: The queue qfree is intended for utilization of free resources, after a project has exhausted all of its allocated computational resources (Does not apply to DD projects by default; DD projects have to request persmission to use qfree after exhaustion of computational resources). It is required that active project is specified to enter the queue. Consumed resources will be accounted to the Project. Access to the qfree queue is automatically removed if consumed resources exceed 120% of the resources allocated to the Project. Only 180 nodes without accelerators 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.

An PI needs explicitly ask support for authorization to enter the queue for all users associated to her/his Project.
***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).

***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 nonzero remaining resources is specified to enter the qmic. All 864 MICs are included.
