VisIt on Aurora¶
Getting Started¶
As of June 2025, the latest VisIt version installed on Aurora is 3.4.2.
Follow these steps to install VisIt on your local machine:
- Download and install VisIt for your local platform (macOS, Windows, Linux). The version you download must match the server version installed on Polaris. Use this page
- Download the Aurora host profile for VisIt (you may need to right-click and choose "Save link as..." or "Save target as...")
- Copy this file to a file called
~/.visit/hosts/host_anl_aurora.xml
on Mac or Linux. For Windows, specify the equivalent path.
Note: VisIt allows the user to download host profiles for ANL, but all these settings are outdated. We are working with the VisIt developers to update the ANL host list.
Additional information for using VisIt in client/server mode is available here.
Running VisIt¶
- Start up VisIt on your local machine.
- Click File -> Open File and choose "ANL Aurora" from the "Host" dropdown.
- You'll be prompted for your password; enter your ALCF authenticator app response.
- When you open a selected file, it will launch a job on Aurora.
- You will need to specify the "Bank" (Project) to use when VisIt submits jobs to the queue on Aurora. Specify a project in the Options box.
- If your environment doesn't get sourced correctly with non-interactive SSH, you can set the default project to use under Options -> Host profiles.
Warning
Don't change the contents of the "Machine file" field (it should be $PBS_NODEFILE
).
Tip
The default Launch Profile is set to serial. We recommend leaving this setting in its default value, but using the parallel method to launch jobs on Aurora.
Warning
Don't change the contents of "launchMethod". It must be qsub/aprun
even though Aurora does not use aprun
.
- The Aurora host profile linked above contains an empty user name. Make sure to update with your user name.
- If you'd like to change other job parameters (like the number of processes, nodes, and walltime), you can do so. Please enter time in the format required by the PBS scheduler (i.e., 1:00:00 for one hour).
- If you'd like these changes to be used as your default, be sure to save them using Save Settings under the Options menu.
