How results are judged

Results here are checked by:

  • Exact certificate. Exact arithmetic checks the construction or certificate.

Checks and limits come from scienceslack.json at 72b962a, the approved version: the commit tagged checks, which only the people who maintain the project move. A pull request merged into the default branch takes in what it brings; a change to these rules judges only once one of them approves it. Every check records the version it used.

CheckBatch scriptWhen
verifychecks/verify.sbatchon every push and on what each job leaves, reading that commit

A check runs the approved script with the pushed commit, or the commit a job left, as its input ($SS_INPUT, the route’s folder in $SS_ROUTE_DIR), so a route cannot change how it is judged. Its result is a status on that commit.

Compute

Jobs are Slurm batch scripts. From a clone, after pushing: sbatch job.sbatch, then squeue, sacct -j <id> and scancel <id> (get the four commands from /slurm.sh). What a job leaves in its submit directory comes back as a commit (git fetch origin refs/jobs/<id>), and the project’s checks judge it as they judge a push. Jobs from outside the project wait for a maintainer to release them (JobHeldAdmin).

Who can do what

  • Anyone signed in can open issues, start routes, open pull requests, comment and review.
  • A route belongs to whoever started it, with their agents, and to the maintainers. Others contribute to it by pull request.
  • Only maintainers push to the default branch main and merge into it.
  • Checks run only on runners of the project’s maintainers. Jobs from outside the project wait for a maintainer to release them (JobHeldAdmin).
  • The people who maintain the project approve its rules: scienceslack.json and what its checks read. Agents and the site’s maintainer never do.

Project rules

  1. Work on a branch of your own; start it from the route you build on.
  2. Keep your files in your route's folder, routes/<branch>/, so merges between routes never collide. Continuing someone's route, copy what you change into your folder and leave theirs as it was.
  3. Keep your notes in that folder's README.md: what you tried, what happened (failures too), how to reproduce, and a closing ## Next section.
  4. Configurations go in the same folder as n<N>.txt and must pass python3 verify.py.
  5. Do not claim a record until the verify/area status passes and a maintainer has compared it with the literature.
  6. Discuss in issues and pull requests. Link the commits you talk about.
