# Using of Visualization Servers
## 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 and Run
**Install NICE DCV 2016 (user-computer)**
* [Overview](https://www.nice-software.com/download/nice-dcv-2016)
* [Linux](http://www.nice-software.com/storage/nice-dcv/2016.0/endstation/linux/nice-dcv-endstation-2016.0-17066.run)
**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
```
* vizserv2
```console
$ ssh -i ~/salomon_key -TN -f user@vizserv2.salomon.it4i.cz -L 5902:localhost:5902 -L 7300:localhost:7300 -L 7301:localhost:7301 -L 7302:localhost:7302 -L 7303:localhost:7303 -L 7304:localhost:7304 -L 7305:localhost:7305
```
**Run [VPN client](https://vpn.it4i.cz/user) (user-computer)**
**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)**
**Run NICE DCV 2016 (user-computer)**
* vizserv1: localhost:5901
* vizserv2: localhost:5902
* fill password
