Paraview cluster how to#
Paraview cluster install#

Then comes the next commands: cluster:~> ssh node1234.$SERVERĬluster:~> ssh -R 22222:localhost:22222 node9876.$SERVERīut then it starts to print the following line on the shell, multiple times until the simulation is finished: Local:~$ ssh -XL 11111:node1234.$SERVER:11111 this point on, I am able to connect my local ParaView GUI (version 5.7.0, as downloaded from ParaView’s website) to the pvserver running on compute node 1234 of the cluster. The pvserver being used is the headless (osmesa) 5.7.0, as downloaded from ParaView’s website. Say that I have a simulation job 9876 running in one of the compute nodes of the cluster, and a pvserver job 1234 running on another compute node. Option to starting paraview and pvserver.I am having problems to connect live to a simulation running on a Linux cluster. If you have trouble with OpenGL visualization, you may need to add the '-mesa' This only works properly if the SSH command can be executed by Paraview Ssh -R XXXXX:localhost:XXXXX /opt/hlrs/non-spack/vis/paraview/ParaView-5.11.0-osmesa-MPI-Linux-Python3.9-x86_64/bin/pvserver -reverse-connection -client-host=localhost -server-port=XXXXX 'Client / Server (reverse connection)', specify the port XXXXX as above andĬhange the Startup Type to Command with the following command: Utilizing the reverse connection with a reverse tunnel. It is also possible to have paraview itself performing the pvserver startup by (Or configure this in the connect server option of the Paraview interface). Then it is possible to connect to that from your local machine Ssh -L 11111:localhost:XXXXX /opt/hlrs/non-spack/vis/paraview/ParaView-5.11.0-osmesa-MPI-Linux-Python3.9-x86_64/bin/pvserver -server-port=XXXXX Please use your username number for that, so on your local system you run: In this case, we can provide the pvserver start directly in the ssh tunnelingĬommand, though for that you need to pick a unique, not yet used port number. To run it on the frontend itself, however in this case no computingĬapabilities are used on the cluster, and the rendering has to be performed Instead of running the pvserver on some compute node it is also possible Then we can start the Paraview on our own computer and with that Ssh -N -L 11111::XXXXX shell must now remain open in the background while the In order to connect a local Paraview to the pvserver on that node,Īn SSH tunnel needs to be created according to the following scheme

The pvserver then gives us the info on how to connect to it, Module load vis/paraview/5.11.0-MPI-Linux-osmesa Listen on a dedicated port XXXXX, use the number from your In the interactive shell we then run the pvserver and tell it to This approach tends to be slower than using theįirst we start a job that provides a pvserver: The version is important, otherwise the server will refuse the connection. We can also use a local Paraview Client to connect with aįor this we need a Paraview installation in version 5.11 on the local Instead of performing the visualization in a VNC session on the cluster, Note: ignore warnings about zink written by paraview.Īlternative with local Paraview and Paraview server Module load vis/paraview/5.11.0-MPI-Linux Then open a terminal in this session and do the following:

Ssh -N -L :n002701: this tunnel, it should then be possible to start vncviewer with: Need to use the ports provided by the script and put the visualization The vis_via_vnc.sh script, however the node name gets lost, you If the vncviewer doesn't support -via, we need to create a separate It should be something along these lines:Ĭonnect to the VNC session via the vncviewer: Local system to connect to the VNC session. The script then tells you what you need to run on your To start a VNC session for visualization, run:

Use a VNC setup on your machine to make use of the visualization.

Run a local Paraview client and connect it to pvserver on the cluster.

Copy the data to your system and visualize completely locally.Thus there are three options for the visualization: Is to use a local Paraview installation and connect to a paraview server on See the section below on the Visualization with VNC.Īn alternative approach to avoid the copying of data to the local system To completely perform the Visualization on the HLRS cluster itself we needĭetails on the production system can also be found in the HLRS Wiki.

Unfortunately, this is currently only very limited possible on the training cluster. On productive systems, the visualization usually takes place directly on the However, this requires the resulting data to be copied from the cluster.

You can install this locally to process the data on your computer.
