Since all VSC clusters use Linux as their main operating system, you will need to get acquainted with using the command-line interface and using the terminal. To open a terminal in Linux when using KDE, choose Applications > System > Terminal > Konsole. When using GNOME, choose Applications > Accessories > Terminal.

If you don't have any experience with using the command-line interface in Linux, we suggest you to read the basic Linux usage section first.

Getting ready to request an account

Connecting to the cluster

  • Open a text-mode session using an SSH client:
  • Transfer data using Secure FTP (SFTP) with the OpenSSH sftp and scp commands.
  • Display programs that use graphics or have a GUI
    • No extra software is needed on a Linux client system, but you need to use the appropriate options with the ssh command as explained on the page on OpenSSH.
    • On the KU Leuven/UHasselt clusters it is also possible to use the NX Client to log on to the machine and run graphical programs. This requires additional client software that is currently available for Windows, OS X, Linux, Android and iOS. The advantage over displaying X programs directly on your Linux screen is that you can sleep your laptop, disconnect and move to another network without loosing your X-session. Performance may also be better with many programs over high-latency networks.
    • The KU Leuven/UHasselt and UAntwerp clusters also offer support for visualization software through TurboVNC. VNC renders images on the cluster and transfers the resulting images to your client device. VNC clients are available for Windows, macOS, Linux, Android and iOS.
