-VSC5 is a high performance cluster that consists of different kind of nodes. When you login using SSH at ''vsc5.vsc.ac.at'', you reach one of the login nodes that can be used to prepare the software environment, but that should not be used to perform any resource-intensive calculations. When you are finished preparing the software / scripts that you want to run, you submit a job file to the queue, which is later on executed on compute nodes (some of which have GPUs) once the resources become available.
+VSC5 is a high performance cluster that consists of different kind of nodes. If you are outside of the university network, you need to use the jump host ''vmos.vsc.ac.at'' to reach VSC. (Note: Not all users are enabled to use the jump host.) To do that, use ''ssh -J username@vmos.vsc.ac.at username@vsc5.vsc.ac.at''.

 At VSC5, SLURM is used as scheduler for queuing jobs. You can find an introduction to SLURM in the course material of the VSC introduction course at:

 Every SLURM job needs a job description file. These files are kind of shell scripts, but with some additional boilerplate at the top. Here is an example file:
