N.B Please remember to clean up your sessions once you have completed your work.  Instructions on how to do this are described here.

Session creation

The first thing you need to do is create a virtual desktop session to connect to:

...

The Viking virtual desktop session can be used like any other Linux desktop session. For those of you who are unfamiliar with using a Linux desktop, a brief overview of the desktop envrionment environment available on Viking, Gnome 3, can be found here. Most importantly, if you open the 'Terminal' application, you can use Viking in the same way as you are used to using it, with the added ability to run graphical applications seamlessly on the compute nodes. An example of this follows:

  1. Open the 'Terminal' application from 'Applications → Favourites → Terminal':
  2. In the terminal, run the command 'start-interactive-session.sh`. This command takes the same parameters as the `srun` command used to run interactive jobs in a Viking terminal session. For more information on these parameters, see our documentation on submitting jobs to Viking. In the example below, I have requested an interactive session with 1 core and 4GB of memory:
  3. Load the module(s) needed to run the application that you would like to use, and run the application. In the example below, I have loaded the `math/MATLAB/2018a` module, and run `matlab`:
  4. MATLAB is now running on the Viking compute node `node065`!

Please note that the usual resource limitations apply to jobs run interactively, which can be found in our documentation about partitions and their limits. When you are finished working interactively, be sure to exit your interactive session by running `exit` in the terminal.
