FAQ
How do I get an account?
See Requesting access — in short: contact the staff with your firstname.lastname username, an SSH public key and your project name.
Why can't I connect to Chacha or Disco?
You have to connect from the school network or the HEVS VPN — the compute nodes are not reachable from the open internet. See Connecting.
Why can't I use the VSCode remote-SSH plugin?
Its constant file scanning puts a real load on shared servers, so don't use it on our machines :

- https://learn.microsoft.com/en-us/answers/questions/1221136/visual-studio-2022-clear-local-caches
Currently your vscode caches are automatically removed from our servers.
Where should I put my data?
Not in /home/user.name/ — it is quota-limited on purpose. Use the datasets / shared_datasets / results symlinks, and a filer mount for anything that must survive long-term. Full rules in Storage and quotas.
Why did my disk quota fill up?
Usually the Apptainer cache. Run apptainer cache clean (weekly is a good habit), and keep your .sif files in datasets/, not in your home. See Storage and quotas.
Can I schedule something with cron?
Yes, but ask first : your user must be added to the /etc/cron.allow whitelist.
