X11 Forwarding and GUI Applications

While many applications on the supercomputer operate directly within the terminal, others utilize graphical interfaces (GUIs) for interaction, such as Gaussian View, VMD, or even standard applications like Firefox. X11 forwarding allows users to run these GUI-based applications remotely by transmitting graphical output to their local machines. To use graphical applications, follow one of the recommended methods described below or an equivalent alternative.

X11 Forwarding​

Ensure your SSH client supports X11 forwarding. See our page on recommended terminal clients.

To enable X11 forwarding, include the -X flag in your SSH command:

ssh -X asurite@sol.asu.edu
note

You will be prompted for a Duo Push notification when connecting via SSH. Make sure to have your 2FA device ready.

Web Portal​

Alternatively, you can access graphical applications through the web portal by launching an interactive virtual desktop session. This approach displays GUI applications within a native windowing environment hosted on the supercomputer, bypassing the need for SSH-based X11 forwarding. Simply initiate a desktop session from the portal to automatically enable GUI interactions.

Advanced Graphics (OpenGL / WebGL)​

Certain applications require enhanced graphical performance via OpenGL. Since supercomputer hardware is primarily server-grade and lacks native OpenGL support, you must load an emulation module for optimal graphical performance. The Mesa3D libraries, comprising open-source implementations of OpenGL, OpenGL ES, Vulkan, and OpenCL, provide this emulation. See our OpenGL/WebGL Support page for detailed instructions on enabling OpenGL support within your graphical applications.
