Use VNC to connect to supercomputers

VNC advantages over X-forwarding:

  • faster and responsive
  • stable and established means of graphical remote control.
  • consumes kB/sec instead of MB/sec.
  • deliberately or accidentally disconnect, and when you reconnect, your VNC desktop is still there as it was.
  • Wayland replaces X11, and Wayland does not forward over the network

How to use VNC to HPC:

  1. RealVNC Viewer is free of cost.
  2. Start VNC server on HPC
  3. Connect to VNC server using its IP address
