| Running Paraview | 03 December 2020 | software, paraview, mesa, OpenGL | This document describes how to run ParaView in the Merlin6 cluster | merlin6_sidebar | /merlin6/paraview.html |
Requirements
NoMachine 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.
ParaView
PModules
Is strongly recommended the use of the latest ParaView version available in PModules. In example, for loading paraview:
module use unstable
module load paraview/5.8.1
Running ParaView
For running ParaView, one needs to run it with Mesa support.
The OpenGL version runs with just the paraview command, however, Paraview with OpenGL support will not work on the Merlin6 login nodes. This is because Merlin is based on RHEL7 (which is a pretty old Operative System) and integrating OpenGL might require major changes. Hence, for Merlin6 we currently provide Mesa support only. We expect that for 2021 it would be also possible to run with OpenGL support.
As said, for running ParaView in Merlin6, on needs to run with Mesa support, and can be done as follows:
paraview-mesa paraview
As pointed out in the Requirements section, NoMachine is the only supported (and performance) way.
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:
# Warning: only for Paraview 5.4.1 and older
paraview --mesa
