This article note specific information for launching ParaView Server on compute nodes and connect local ParaView with it.


Passwordless SSH need to be activated as well as connection established with Port forwarding.

Furthermore, the local (on your local machine) ParaView version need to match the version loaded on the HPCs.

Launch ParaView server

First, as mentioned, establish a SSH session with Port forwarding, another port in the range [2000-65000] should be selected:

ssh -Y -L 15051:localhost:15051

Then load the modules:

module load ParaView

The ParaView version can be displayed using:

module list ParaView

Currently Loaded Modules Matching: ParaView
  1) ParaView/5.8.1-foss-2020b-mpi

Thus, in this example ParaView 5.8.1 need to be used in the local machine.

To start the ParaView server on a compute node you can use:

pvserver-parallel 15051   ### use your selected port number

This submits a job with 1 core for 1h in the epyc2 partition. The tool prints a reminder to stop the job if not required anymore and shows the queueing information regularly:

ParaView remote Server submitted to compute nodes
  when finished please kill the server using:
     scancel 2394231
job 2394231 status:
 2394231      epyc2  PENDING                      N/A
pvserver ready to connect on port 15051.
When finished, please stop ParaView Server using
 scancel 2394231

Please cancel your job with scancel $JOBID or all your running jobs using scancel -u $USER if not needed anymore.

Additional resources can be requested by --slurm-args="" option with the desired slurm options, e.g. 3 cores for 20 min:

pvserver-parallel 15051 --slurm-args="--cpus-per-task=3 --time=00:20:00" 

In addition ParaView arguments can be added without any prefix.

Connect local client

Finally, the client on your local machine can connect using localhost and the selected port, here 15051. E.g. using pvpython:
