## Requirements
|
|
|
|
**[NoMachine](/merlin6/nomachine.html)** is the official **strongly recommended and supported** tool for running *ParaView*.
|
|
Consider that running over SSH (X11-Forwarding needed) is very slow, but also configuration might not work as it also depends
|
|
on the client configuration (Linux workstation/laptop, Windows with XMing, etc.). Hence, please **avoid running Paraview over SSH**.
|
|
The only exception for running over SSH is when running it as a job from a NoMachine client.
|
|
|
|
## ParaView
|
|
|
|
### PModules
|
|
|
|
Is strongly recommended the use of the latest ParaView version available in PModules. In example, for loading **paraview**:
|
|
|
|
```bash
|
|
module use unstable
|
|
module load paraview/5.8.1
|
|
```
|
|
|
|
### Running ParaView
|
|
|
|
For running ParaView, one can run it with **VirtualGL** to take advantatge of the GPU card located on each login node. For that, once loaded, you can start **paraview** as follows:
|
|
|
|
```bash
|
|
vglrun paraview
|
|
```
|
|
|
|
Alternatively, one can run **paraview** with *mesa* support with the below command. This can be useful when running on CPU computing nodes (with `srun` / `salloc`)
|
|
which have no graphics card (and where `vglrun` is not possible):
|
|
|
|
```bash
|
|
paraview-mesa paraview
|
|
```
|
|
|
|
#### Running older versions of ParaView
|
|
|
|
Older versions of ParaView available in PModules (i.e. *paraview/5.0.1* and *paraview/5.4.1*) might require a different command
|
|
for running paraview with **Mesa** support. The command is the following:
|
|
|
|
```bash
|
|
# Warning: only for Paraview 5.4.1 and older
|
|
paraview --mesa
|
|
```
|
|
|
|
#### Running ParaView interactively in the batch system
|
|
|
|
One can run ParaView interactively in the CPU cluster as follows:
|
|
|
|
```bash
|
|
# First, load module. In example: "module load paraview/5.8.1"
|
|
srun --pty --x11 --partition=general --ntasks=1 paraview-mesa paraview
|
|
```
|
|
|
|
One can change the partition, number of tasks or specify extra parameters to `srun` if needed.
