Visualization with ParaView and VisIt

ParaView and VisIt are interactive applications usually run on your local desktop. They both support a large variety of different file formats. For details about the formats supported by each software, consult:

  1. File formats supported by VisIt
  2. File formats supported by ParaView

The default operation mode of VisIt and ParaView is serial. However, they both can be coupled with a parallel server, running on one of the production machines at CSCS. We differentiate between two operative modes:

Batch mode

Both applications can execute a parallel python script. Of course the python commands will differ between the two applications. 

We refer you to the manuals or the on-line script generation features of both tools to create the necessary commands. Once a script is ready, it can be launched with SLURM, from any node. Your choice of the platform to use (pilatus, daint, dora) will depend on which /scratch filesystem your data is located on, and if you need GPU accelerated graphics, or software-rendering.

  • ParaView users can follow the example in /apps/{pilatus,daint,dora}/ParaView/{coloredSphere.sh,coloredSphere.py}

  • VisIt users can follow the example in /apps/{pilatus,daint,dora}/VisIt/{parallel_run.sh, parallel_run.py}

Interactive mode

VisIt and ParaView are tuned to establish connections to remote servers without the need to use a VNC connection. The following pages explain how to proceed.
