CSC does not anymore recommend the usage of NoMachine for running remote graphics on CSC supercomputers. Instead, please use the Puhti web interface.

The NoMachine Client enables remote graphical work on CSC supercomputers from your local computer. The speedup vs. X11 (native or emulated) can be many fold, so you will experience substantial improvement. Note that with NoMachine you don't need X-emulators or X-term (in Linux).
