An interactive data analysis and visualisation tool with 3D rendering capability

Our ParaView modules include the pvserver only (see manual below).
We do not recommend to use the ParaView GUI directly:
X-window forwarding has high latency and the images of our compute nodes bring only a minimal set of graphic-drivers/libs.

Description

ParaView is an open-source, multi-platform data analysis and visualization application with interactive 3D or programmatical batch processing capabilities

Read more on ParaView home page. For a manual visit the Paraview Guide page.

To see our provided versions type:

module avail paraview

Example Use

Start an interactive job and enter your node
```
srun --partition=cpu-clx:test --ntasks-per-node=96 --pty bash
```
If a lot of memory/RAM is needed, especially the following "fat" partitions are suitable:
cpu-clx:large, cpu-clx:huge (see Slurm partition CPU CLX)
cpu-genoa (see CPU Genoa partition)
Load (default) module on your (fat) node
```
module load paraview
```
Start the Paraview server on your (fat) node
```
mpirun -n $SLURM_TASKS_PER_NODE pvserver --server-port=12345
```
Wait a few seconds till your Paraview server provides a connection.
‎ ‎ ‎ ‎
@local: Start a ssh tunnel on your preferred terminal to access the port of the node via a login node
```
ssh -N -L 12345:cpu-clx####:12345 <user>@blogin.hlrn.de
```
Leave this terminal window open to keep the tunnel running. Before setting up a ssh tunnel check if your standard ssh login works. If you are a windows user without a proper terminal we recommend MobaXterm.
‎‏‏‎ ‎
@local: Start your ParaView client GUI and access your Paraview-Server at
```
cs://127.0.0.1:12345
```
Please note: the first two version numbers of your local ParaView client have to be the same as the remote Paraview-Server. You can download various ParaView versions here. After calling "module load paraview" the version of the loaded module will be displayed.
