Similarly, I’m also keen to know if you’ve found any of these emails particularly useful. I’m always keen to hear other ways of doing things & your experience with this stuff. If I’m doing any of this wrong then please let me know, partly so that I can improve, but also so that I can share it with the rest of the class. Using this method there’s no need to open any additional ports & you also won’t need to keep updating the server address in ParaView. You should be all set – go, go, post-pro. If you go back to your SSH connection you should see a success message reporting your newly made connection. Select your new configuration from the list & either double-click it or click Connect.

#PARAVIEW CLUSTER MANUAL#

Leave the startup type as Manual (you’ve already started it) & click Save. The defaults should look something like this…Ĭhange the name to something more original & click Configure. In your local ParaView, go to File > Connect & click Add Server. Ssh -L 11111:127.0.0.1:11111 connected, start pvserver and it’ll patiently wait for you to start ParaView on your local machine (leave the SSH connection open). If you can’t SSH to the machine, then you’ve got bigger problems, sorry. Change to whatever your user & host are called. When you SSH to the remote machine, use the -L switch to forward the port along the SSH connection (rather than having to open any additional ports). Try this tweak (thanks to this comment on the ParaView mailing list) 🙏 The problem comes when you can’t (or don’t want to open ports on your firewall). It sits there listening on port 11111 (you can change this) until I fire up a local ParaView client and point it at the server. There are various ways to start the server, but I usually just SSH into a remote machine & start pvserver manually. Once connected, the experience is pretty much like having everything on your local machine – slick. Fire up a server on the machine that has access to your data, fire up a client on your local machine, connect the two & you’re off to the races. ParaView is built for running in a client/server mode. You will miss all the fun of a superbuild though.įYI: These binaries can also be run in Docker containers, which often don’t have access to their host’s graphics.īy the way, let me know if you want my up-to-date (but probably obsolete) Superbuild crib sheet.

#PARAVIEW CLUSTER DOWNLOAD#

Download & unpack them on your headless machines for instant ParaView. They’re available for the current version (5.9.0) all the way back to version 5.6.0 – check them out here. But, whilst doing my homework & checking my Superbuild notes, I noticed that ParaView now provide headless Linux binaries for download 🥳

#PARAVIEW CLUSTER HOW TO#

That’s what I was going to write about – how to build your own headless ParaView using Superbuild.

#PARAVIEW CLUSTER INSTALL#

In the olden days, if you wanted a version of ParaView that ran headless then you had to compile your own 🥶Įnter, ParaView Superbuild a neat project that takes the sting out of building ParaView (and it’s many dependencies) and (optionally) packaging it up so that you can easily install it on other machines. The headless versions actually perform (almost) as well you’d expect from a machine with graphics hardware. We can do lots with these utilities though – pvbatch can be used to create unattended post-pro using python scripts, pvserver is one half of a client/server arrangement & pvpython gives us a way to interact with the ParaView Python API. Note: When I say headless ParaView, I mean pvbatch, pvserver & pvpython – you can’t actually build a headless ParaView – a graphical user interface without graphics has some usability issues. Another option would be to compile a version of ParaView that doesn’t need graphics hardware or an X-server – headless ParaView. One option would be to rig up a separate post-processing queue on a machine with decent graphics hardware. In the past you had to get a bit creative to get this to work. This means that I’m often running ParaView on machines that have no graphics provision at all – no graphics card, no X-server, no ability to show anything graphical on a screen 🙈 I’ve mentioned before that I do everything on the cluster – mesh, solve and post-pro. Niche ParaView knowledge? Sure, but the cool kids aren’t reading this, so let’s geek out… Headless ParaView

I’ll also throw in a neat way to connect to said machine (especially if you’re behind a firewall). If you ever need to run ParaView on a machine that doesn’t have graphics hardware or an X-server (whether it’s in the cloud or in your closet) then stick with me. So let’s go with headless ParaView instead. This email was intended to be a quick guide to using ParaView Superbuild (bear with me) but, whilst updating my notes, it turns out that things have changed and that’s knowledge you’ll never need 🤷‍♂️ It’s Robin from CFD Engine fresh from another week masquerading as a teaching assistant in the UK’s most-mediocre home school.
