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 window in macOS (formerly OS X), choose Applications > Utilities > Terminal in the Finder.

If you don't have any experience with using the Terminal, we suggest you to read the basic Linux usage section first (which also applies to macOS).

Getting ready to request an account

  • Before requesting an account, you need to generate a pair of ssh keys. One popular way to do this on macOS is using the OpenSSH client included with macOS which you can then also use to log on to the clusters.

Connecting to the machine

  • Open a text-mode session using an SSH client: OpenSSH ssh command or JellyfiSSH.
  • Transfer data using Secure FTP (SFTP) with the OpenSSH sftp and scp commands, Cyberduck or FileZilla.
  • Running GUI programs or other programs that use graphics.
    • Linux programs use the X protocol to display graphics on local or remote screens. To use your Mac as a remote screen, you need to install a X server. XQuartz is one that is freely available. Once the X server is up and running, you can simply open a terminal window and connect to the cluster using the command line SSH client in the same way as you would on Linux.
    • On the KU Leuven/UHasselt clusters it is possible to use the NX Client to log on to the machine and run graphical programs. Instead of an X-server, another piece of client software is needed. That software is currently available for Windows, macOS, Linux, Android and iOS.
    • 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.
