Graphical Applications

Work in Progress

Not all visualization services are fully available yet. Until the official launch of HoreKa 2 (Phase 2) in September, we will be bringing services online gradually. Some services may therefore not yet be available or fully functional. Functionality may be incomplete or subject to change. Thank you for your patience!

NHR@KIT systems support several methods for running graphical applications remotely. The right choice depends on your use case:

  • X11 forwarding is the simplest option for running individual GUI applications. It requires no additional setup beyond an SSH connection, but is limited to software rendering and performs poorly over high-latency connections. → X11 Forwarding
  • VNC-based methods provide a full remote desktop environment. They support hardware-accelerated OpenGL rendering via GPU and are better suited for interactive 3D visualisation or applications that require a persistent desktop session. → JupyterHub Desktop, start_vnc_desktop
  • Server-client rendering offloads all rendering to the compute node and streams only the final images to a lightweight local client. This is the most efficient approach for large-scale 3D datasets and is supported by applications such as ParaView. → Server-Client Rendering
