![]() This setup requires to have paraview installed on a personal computer with a version matching the one available on the Euler:Īt the time of writing, you can download version 5.8.0 or 5.9.1 here. In this documentation, we are explaining how to achieve such a setup. Sending back all the data is too expensive, so the server does not only provide the data back to the user but also perform some off-screen rendering. In order to simplify its usage, ParaView can be run in a "client-server" mode where the user runs the client on his/her own machine (GUI) and connects to the server in order to access the data. It can also be run as a single-computer application." ParaView is an application designed for data parallelism on shared-memory or distributed-memory multicomputers and clusters. It is an application built on top of the Visualization Toolkit (VTK) libraries. It has a client–server architecture to facilitate remote visualization of datasets, and generates level of detail (LOD) models to maintain interactive frame rates for large datasets. ![]() If something goes wrong, a message box will provide information.According to wikipedia: "ParaView is an open-source multiple-platform application for interactive, scientific visualization. The setup process takes a little while so be patient. ![]() ![]() There will be some options to select in the next screen and then Paraview will connect after pressing OK. Select the "University of Iowa Argon" configuration and select Connect. This screen will likely look different, depending on the server configs that you have already loaded. The screen should then look similar to that below. Navigate to the pvsc file that you previously downloaded and load that file. On the next screen, click on Load Servers. Note that the version shown here will likely look a little different, depending on version and OS used.Īfter launching Paraview, click on the Connect to Server button. To set up Paraview to use the HPC system, launch the Paraview client that was previously installed. Paraview downloads are available at the Download | ParaView web page. You must download the paraview client binary of that same version. You should download the servers definition file which sets up access to our systems. To make setup easier, a server configuration file for Argon is provided. For Mac and Linux machines you may enter a one-time Duo code, in addition to specifying "push". On a Windows machine, Duo will auto push to your device, so you must have a device set up for that. Second, you must pass Duo 2-factor credentials. ![]() There is no way to type a password when Paraview connects so this step is crucial. First off, you must have passwordless SSH setup. Paraview can be a little difficult to set up, particularly on Windows machines. Typically, the only way to access compute nodes on an HPC system is through a queue system so this allows paraview to take advantage of those resources. Paraview will submit itself as a job to a queue system on the processing servers. In addition to having the processing done on a single server, paraview can use MPI to connect to multiple server nodes to process very large data sets. In this model, paraview can connect to your data on a remote system, process the graphics elements on the remote system, but render and display the graphics on your local workstation, taking advantage of hardware acceleration. It overcomes the issue of poor performance of graphics over a network by splitting the processing and rendering over multiple servers. Paraview is a visualization package for large data sets. ![]()
