Paraview can be a little difficult to set up, particularly on Windows machines. First off, you must have passwordless SSH setup. There is no way to type a password when Paraview connects so this step is crucial. Second, you must pass Duo 2-factor credentials. Since there is no prompting the DUO_PASSCODE variable must be set in order to pass a code to Duo when Paraview connects via ssh. This can be handled via the paraview connection settings for Mac and Linux, but not on Windows. Windows systems require a hardcoded value be set prior to launching Paraview. This can be done in Putty by setting the DUO_PASSCODE variable in the session section of the settings. See the Two-factor authentication page for details.
The current version of Paraview is 5.4.0. You must download the paraview client binary of that same version. Paraview downloads are available at the Download | ParaView web page. In addition to the client, you should also download the servers definition file which sets up access to our systems.

To set up Paraview to use the HPC system, launch the Paraview client that was previously installed. Then follow the steps below. Note that the version shown here will likely look a little different, depending on version and OS used.
After launching Paraview, click on the Connect to Server button.
On the next screen, click on Load Servers. Navigate to the pvsc file that you previously downloaded and load that file. The screen should then look similar to that below.
Select either the Parallel or Serial configuration and select Connect. There will be some options to select in the next screen and then Paraview will connect after pressing OK. Note that the parallel configuration will send a job to SGE and will only launch a job if there are sufficient resources available.
