Paraview

Paraview is only installed on the cluster as pvserver for Server-Client connections.

NOTE: The versions of Paraview on the Server and Client side must be identical! Currently, versions 5.10.1 and 5.12.1 are available on the cluster (Server) side (modules “paraview/5.10.1” and “paraview/5.12.1”). This version can be freely downloaded for your computer (Client) at Paraview-download. Older version 5.10.1 is kept for its compatibility with openfoam-org/12, it is also native for OS Ubuntu 22.04.

The SSH login must be done with graphics support, i.e. the -Y switch (Windows users, see. cluster/connections)

ssh -Y user@kraken

After loading the module

[user@kraken ~]$ ml paraview

pvserver can be started on the admin node

[user@kraken ~]$ srun -p NoCompute pvserver

even in parallel in the NoCompute queue directly from the command line

[user@kraken ~]$ srun -p NoCompute -n 4 pvserver

or by using the script for “sbatch”:

#!/bin/bash

#SBATCH --job-name=Paraview_test
#SBATCH --output=slurm_out.txt
#SBATCH -p NoCompute
#SBATCH -N 1
#SBATCH -n 4

ml paraview/5.10.1-11.2.0

srun pvserver

Parallel running greatly speeds up program response, up to 12 cores can be used with the NoCompute queue.

• Connect Paraview on your local machine using File > Connect… or the icon.

• If the connection was not previously created, press Add Server in following screenshot:

• and fill in information from screenshot:

• (pvserver prints the necessary connection data to the terminal at startup)

• All that's left is to confirm with Configure still within the same screenshot and then press Save on the next window:

• Now the connection should be possible using Connect

If the version of the program on the Server side does not match the version on the Client side, even with a properly configured connection, you will get a following error:
