Graphical Login (VNC)
Graphical Login (VNC) only with JURECA login possible.
Remote visualization, either implemented within visualization applications themselves or through server software,
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?

IMPORTANT: Use hardware acceleration in your VNC session
vglrun:
Any OpenGL application running in your VNC session should be started with vglrun to use the hardware acceleration provided by the visualization nodes.
e.g. ParaView
Open a terminal in your VNC session and:
# What versions of ParaView are available? module spider ParaView # load ParaView dependency module load intel-para # load ParaView module load ParaView
# start ParaView Server and GUI using VirtualGL for hardware acceleration srun -n 24 vglrun pvserver vglrun ParaView
Connect to the pvservers on localhost:11111
e.g. VisIt
Open a terminal in your VNC session and:
# change Stage module use /usr/local/software/jureca/OtherStages module load Stages/.Stage1 # What versions of VisIt are available? module spider VisIt # load VisIt dependency module load intel-para/2015.07 # load VisIt module load VisIt/2.10.0
# start VisIt using VirtualGL for hardware acceleration vglrun visit -hw-accel
Hints
- press F8 to enter VNC-Viewer Options (example: toggle to full screen)
- sync clipboard between client and server
- To reset your VNC-password delete ~/.vnc/passwd
