Machines and Versions

See LC visualization software page.


Links to the latest version exist in /usr/tce/bin.

Multiple versions may be accessible via modules. Type module avail vapor to see the available options. You can specify a particular version in the module command, e.g., module load vapor/2.6.0.

The actual installation directories are in /usr/tce/packages/vapor.


We recommend using the module load vapor command to setup your PATH and any other needed environment variables.

Alternatively, you may run the appropriate vapor-setup.* script manually. Attempting to run vaporgui without setting up your environment first will print additional instructions for using this setup script.


We recommend typing module load vapor before running any VAPOR utilities.

You can launch the main VAPOR application by typing vaporgui.


Information about VAPOR 3 is available on their documentation website.
