![]() Once you are connected, you can connect to an interactive compute node using the -X switch, for example qsub -I -X -l select=1:ncpus=16:mem=60gb:interconnect=fdr,walltime=10:00:00 It comes with built-in X11 support, so you don't need to do any extra steps. Windows usersįor Windows users, we recommend using MobaXTerm to connect to Palmetto. The process of enabling X11 tunneling is slightly different for Windows, Mac, and Linux users. VNC is a bit trickier to set up, but it is faster and more versatile. some graphics-heavy software that uses a lot of OpenGL might not work with X11 tunneling.īoth of these problems can be solved using VNC instead of X11 tunneling.It will definitely be slower than running it on your local computer. running a graphical program through an X11 tunnel might be slow.It allows you to run a graphical application on a Palmetto compute node, and to control it from your local computer. One way to run graphical software on Palmetto is to use X11 tunneling. Setting $DISPLAY to an IP or hostname will not work.Running graphical software on Palmetto with X11 tunneling The environment variable $DISPLAY must be left as SSH sets it, which is to a random local port address. If you had previously set your $DISPLAY environment variable to your local IP or hostname, you must remove any set/ export/ setenv of this variable from your login scripts. SSH will set the remote environment variable $DISPLAY to "localhost:XX.YY" when this is working correctly. MobaXterm: Select "New session" and "SSH." Under "Advanced SSH Settings" check the box for X11 Forwarding.To be certain it is enabled, you may use ssh -Y. ssh: X11 tunneling should be enabled by default.Once you are running an X11 server, you will need to enable X11 forwarding/tunneling in your SSH client: Link to section 'Enabling X11 Forwarding in your SSH Client' of 'SSH X11 Forwarding' Enabling X11 Forwarding in your SSH Client ThinLinc is a service that allows you to connect to a persistent remote graphical desktop session. ThinLinc is an alternative to running an X11 server directly on your Mac computer.Run the installer, select the X11 option, and follow the instructions. X11 is available as an optional install on the Mac OS X install disks prior to 10.7/Lion.It includes X11 support for remote displays, SFTP capabilities, and limited SSH authentication forwarding for keys. MobaXterm is a small, easy to use, full-featured SSH client.ThinLinc is an alternative to running an X11 server directly on your Windows computer.ThinLinc is an alternative to running an X11 server directly on your Linux computer. ![]() If you are logged in to a graphical environment on these operating systems, you are already running an X11 server.
