...
Spawner

Spawning the Jupyter notebook environment on the JupyterHub host. Slurm job flags not needed.
Slurm tools, Modules, Remote desktop environment are available.
Noctua 2 (via Slurm)
Spawning the Jupyter environment inside a Slurm job (on a compute/gpu/fpga node) on Noctua 2. Note: You need to specifiy Slurm job flags.
Preset scopes
Select who can use your preset. You or one of your compute time projects.
Default URL
The URL to which JupyterHub redirects when the server is started.
