    1818* is application-independent (no need for remote visualization support inside the specific application).

    20 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.
     20A broad variety of Linux applications with graphical user interface and/or need for OpenGL can be used directly on the supercomputers via remote visualization.
    2121Multiple software solutions for remote visualization are possible from which we recomment on our system VNC or Xpra.
     22Our decision is based on the mandatory requirement for support of
     23* server-side rendering with OpenGL (using VirtualGL)
     24* optimized for low bandwidth connections
     25* client-support on many operating systems (Linux, MaxOS, Windows, etc.)
     26* flexible use in user specific setups

    2328In general one can destinguish between '''remote desktop''' and '''remote window''' solutions.\\
    2429While 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.

    26 The first choice and recommended, full-blown and one-click solution for remote visualization providing a remote desktop on frontend nodes and compute nodes is provided using '''Virtual Network Computing (VNC)''' over the login tool Strudel. \\

     32We recomment to use VNC + Strudel as our first choice as it is integrated into our batch system at the moment most efficiently.

     34VNC + Strudel ...
    2935* provides a complete graphical and '''remote desktop'''
    30 * is platform-independent (VNC viewers are available for almost any operating system)
     36* survives disconnect & reconnect
    3137* multiple clients may connect to a VNC server at the same time sharing the same session (support, presentation, group discussions)
     38* supports easy start of remote visualization jobs over the batch system
     39* supports easy use of multiple compute nodes in remote visualization jobs

     42For access to remote windows we recomment Xpra (X Persistent Remote Applications) as a light-weight solution.

    3545* is a '''remote window''' solution
    36 * is platform-independent (Xpra is available for many operating systems)
     46* survives disconnect & reconnect
    3747* graphical window is send as video stream from server to client.
