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 graphical login using Virtual Network Computing (VNC) simplifies the access to remote visualization.
A broad variety of Linux applications with graphical user interface and/or need for OpenGL can be used directly on the supercomputers via VNC.

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) cross-platform application for Linux, MacOS and Windows Strudel should be used to access remote graphical desktop on JURECA developed by the Multi-modal Australien ScienceS Imaging and Visualization Environment (​MASSIVE) team under the NeCTAR-funded ​Characterisation Virtual Laboratory ................................................................................................................................................................................... ==> Download & Install Instructions <==

Alternatives

I cannot (or do not want to) use Strudel - how do I start VNC manually?

	vncserver/ssh/vncviewer (manual connection for VNC) manual start of VNC server on JURECA manual tunnel for VNC data manual start of VNC viewer on local machine ................................................................................................................................................................................... ==> Install instructions <==

I do not want a full blown remote desktop, give me a lightweight solution:

vglconnect/vglrun (no VNC - only a 3d accelerated "ssh -x") this is a replacment for ssh -x every application window appears as a separate window on the user’s desktop 3D (VGL Transport) with X11 Forwarding 2D (X11) rendering occurs on the client machine ................................................................................................................................................................................... ==> Install instructions <==
