There are basically 3 ways of how to do Remote Visualization with ParaView on JURECA:

Remote Visualization		pro	contra
X Forwarding		easy to use (ssh -X ...)	sending X/OpenGL commands is slow X Server on user workstation required (not a problem on Linux, might be a problem on Windows and Mac) X Server has to be compatible with OpenGL many OpenGL extensions need direct access to GPU
VNC		easy to use, user only needs to install VNC viewer (not the vis app itself) very convenient, full desktop access of remote machine image delivery is fast GPU not needed on remote machine	software OpenGL not integrated in all VNC Servers software OpenGL is slow no parallel visualization
Client-Server mode
