User Specific Limits for JupyterHub

[David Greene]

Hey folks,

I've been using the following in my jupyterhub_config.py to set the spawner limits.

## Maximum number of cpu-cores a single-user notebook server is allowed to use.
c.Spawner.cpu_limit = 20

## Maximum number of bytes a single-user notebook server is allowed to use.
c.Spawner.mem_limit = '16G'

Is there a way to set this on a per-user basis? For example, if I want to set user jack's CPU limit to 0.5 and user jill's CPU limit to 10? 

Can this be done online (without restarting the whole JupyterHub service in systemd)?

Thanks!

As far as I can tell not with the default spawner, but as the spawner
are plugins, you can write your own, or just extend the one you like
to have `cpu_limit` be a per-user value.

If you use a spawner like SlurmSpawner, then it might be easier to
configure this in Slurm itself that have such mechanism and do have
user<-> resources association. I'm guessing other Spawner might have
that as well.

OK, I'll start with that. Thanks for the tip Matthias.
