This article note specific information for launching ParaView Server on compute nodes and connect local ParaView with it.
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 submit03.unibe.ch
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
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: JOBID PARTITION STATE START_TIME 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
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
