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

Modules

Version	Installation path	module file	compiler/MPI lib	comment
5.0.1	/sw/viz/paraview/5.0.1/skl	paraview/5.0.1	gcc/OpenMPI	Available in Emmy (HLRN-IV Gö)
5.7.0	/sw/viz/paraview/5.7.0/skl	paraview/5.7.0	gcc-9.2.0/openmpi/gcc.9/3.1.5	Available in Emmy (HLRN-IV Gö) and Lise (HLRN-IV Ber)

Example Use

@HLRN: Start interactive job. If a lot of memory is needed, especially the fat nodes are suitable:
```
srun --partition=large96 --nodes=1 --ntasks-per-node=96 --mem=747000mb --pty bash
```

@HLRN: Load prerequisite modules

module load gcc/9.2.0
module load openmpi/gcc.9
module load anaconda3
module load llvm/9.0.0
module load paraview

@HLRN: Start Paraview-Server on your fat node bfn####
```
mpirun -n $SLURM_TASKS_PER_NODE pvserver
```
Wait a few seconds till your Paraview-Server provides a connection, typically with the port number 11111.
‎ ‎ ‎ ‎
@local: Start a ssh tunnel on your preferred terminal to access the port of the fat node via a login node of the HLRN
```
ssh -N -L 11111:bfn####:11111 <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
```
localhost:11111
```
Please note: the version of your local ParaView client has 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. Currently it is 5.7.
