### UV2000 SMP
!!! note
14 NUMA nodes available on UV2000
13 NUMA nodes available on UV2000
Per NUMA node allocation.
Jobs are isolated by cpusets.
The UV2000 (node uv1) offers 3328GB of RAM and 112 cores, distributed in 14 NUMA nodes. A NUMA node packs 8 cores and approx. 236GB RAM. In the PBS the UV2000 provides 14 chunks, a chunk per NUMA node (see [Resource allocation policy](resources-allocation-policy/)). The jobs on UV2000 are isolated from each other by cpusets, so that a job by one user may not utilize CPU or memory allocated to a job by other user. Always, full chunks are allocated, a job may only use resources of the NUMA nodes allocated to itself.
The UV2000 (node uv1) offers 3TB of RAM and 104 cores, distributed in 13 NUMA nodes. A NUMA node packs 8 cores and approx. 247GB RAM (with exception, node 11 has only 123GB RAM).

```console
$ qsub -A OPEN-0-0 -q qfat -l select=14 ./myjob
$ qsub -A OPEN-0-0 -q qfat -l select=13 ./myjob
```
In this example, we allocate all 14 NUMA nodes (corresponds to 14 chunks), 112 cores of the SGI UV2000 node for 72 hours. Jobscript myjob will be executed on the node uv1.

* **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, however only 86 per job. Full nodes, 24 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 336 nodes without acceleration may be accessed via the qlong queue. Full nodes, 24 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 \* 48 h)
* **qmpp**, the massively parallel queue. This queue is intended for massively parallel runs. It is required that active project with nonzero remaining resources is specified to enter the qmpp. All nodes may be accessed via the qmpp queue. Full nodes, 24 cores per node are allocated. The queue runs with medium priority and no special authorization is required to use it. The maximum runtime in qmpp is 4 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. 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). An PI needs explicitly ask support for authorization to enter the queue 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, 24 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.
* **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.
