  • CI: Only run SLOTHY when its inputs change
  • CI: Allow requesting SLOTHY with the slothy-tests label

SLOTHY starts a c8g.8xlarge for every PR push and merge_group run,
regardless of what changed. Gate it on a changed-files job, as in
hol_light.yml.

@L-series, please next time check if someone is already assigned to an issue. I have this half finished locally, but you can take over.

@mkannwischer apologies, its late and i completely glossed over the assignee tab.. Won't do that again.

On the topic of SLOTHY however, what do you think of the addition of a per-file gate? I see that most of the time is spent optimizing NTT and iNTT, and so it might make sense to just have a finer grain gate for these two routines (i.e if any other routine is modified, only re-optimize what has been affected)

No worries! Thank you for your contributions.

We are not planning many more asm changes at this point, so the vast majority of re-runs will be triggered by nix flake changes, I believe. For those we have to re-run for all files anyway. I prefer to keep it simple for now.
