+## Remote Visualization Nodes
+
+For remote visualization two nodes with NICE DCV software are available each configured:
+
+| Node          | Count | Processor                         | Cores | Memory | GPU Accelerator              |
+|---------------|-------|-----------------------------------|-------|--------|------------------------------|
+| visualization | 2     | 2 x Intel Xeon E5-2695v3, 2.3 GHz | 28    | 512 GB | NVIDIA QUADRO K5000 4 GB     |
+
+## Resources Allocation Policy
+
+| queue | active project | project resources | nodes | min ncpus | priority | authorization | walltime |
+|-------|----------------|-------------------|-------|-----------|----------|---------------|----------|
+| qviz Visualization queue | yes | none required | 2 (with NVIDIA Quadro K5000) | 4 | 150 | no | 1h/8h |

+
+**Install VPN client (user-computer)**
+
+* [Overview](../general/accessing-the-clusters/vpn-access/)
+
+**Config SSH tunnels (user-computer)**
+
+* ports: 5901, 5902, 7300-7305
+* vizserv1
+
+```console
+$ ssh -i ~/salomon_key -TN -f user@vizserv1.salomon.it4i.cz -L 5901:localhost:5901 -L 7300:localhost:7300 -L 7301:localhost:7301 -L 7302:localhost:7302 -L 7303:localhost:7303 -L 7304:localhost:7304 -L 7305:localhost:7305

+**Login to Salomon (user-computer)**
+
+```console
+$ ssh salomon.it4i.cz
+```
+
+**Remove ~/.vnc/xstartup**
+**Run job**
+
+* qsub -I -q qviz -A OPEN-XX-XX -l select=1:ncpus=4:host=vizserv1,walltime=04:00:00 -N Vizserver1
+* qsub -I -q qviz -A OPEN-XX-XX -l select=1:ncpus=4:host=vizserv2,walltime=04:00:00 -N Vizserver2
+
+**Run vncserver on vizservX**
+
+* check existing vncservers in /tmp/.X11-unix/X* (rm /tmp/.X11-unix/X1 /tmp/.X11-unix/X2)
+* vizserv1: vncserver :1 -geometry 2540x1380 -depth 24
+* vizserv2: vncserver :2 -geometry 2540x1380 -depth 24
+* set password for vncserver
+
+**Run SSH (vizserv1/vizserv2) with tunnels – see 3. (user-computer)**
