Pelle is not ready yet

Pelle is not completely ready yet, hence the content of this page will change.
Also, the content will be shorter and sloppier, until procedures solidify.

How to behave on a login node

On a login node, one can and should do simple things only: it is a resource shared with all other users on that node.

If you need to do more intense calculations, use the Slurm job scheduler.

If you need to do more intense calculations interactively, use an interactive session.
