Graphical Login (VNC)
Graphical Login (VNC) only with JURECA login possible.
Remote visualization, either implemented within visualization applications themselves or through server software,
eliminates the need for off-site file transfers and allows HPC users to run a broad range of visualization tools
in-place on the supercomputer where the data resides and more compute resources are available.
A broad variety of Linux applications with graphical user interface and/or need for OpenGL can be used directly on the supercomputers via remote visualization. Multiple software solutions for remote visualization are possible from which we recomment on our system VNC or Xpra.
In general one can destinguish between remote desktop and remote window solutions.
While remote desktop solutions present a whole desktop environment (on JURECA we run XFCE) in a single window on the user´s workstation, remote window solutions make applications running on JURECA appear on the local desktop as normal windows managed by the local window manager.
A graphical login using Virtual Network Computing (VNC) simplifies the access to remote visualization.
VNC provides a complete graphical and remote desktop by
- transmitting the keyboard and mouse events from your computer to the remote machine and
- relaying the graphical screen updates back in the other direction.
VNC is
- platform-independent (VNC viewers are available for almost any operating system)
- application-independent (no need for remote visualization support inside the application)
- multiple clients may connect to a VNC server at the same time sharing the same session (support, presentation, group discussions)
Ok, what do I have to do?
Strudel (Scientific Remote Desktop Launcher)

Alternatives - RECOMMENDED
I do not want a full blown remote desktop, give me a lightweight solution:
Xpra - screen for X
................................................................................................................................................................................... |

Alternatives - NOT RECOMMENDED
I cannot (or do not want to) use Strudel to start a VNC session - how do I start VNC manually?
vncserver/ssh/vncviewer (manual connection for VNC)
................................................................................................................................................................................... |

I do not want a full blown remote desktop, give me a another lightweight solution:
vglconnect/vglrun (no VNC - only a 3d accelerated "ssh -X")
