Porting to HB

Open gares opened this issue 5 years ago • 15 comments

This Pull Request is about porting the hierarchy of hand declared algebraic structures to the language of hierarchy-builder .

Rules for contributing to this PR:

  • Tick the boxes down here when:
    • the file is taken by you to work on,
    • then when it works (modules depending on it can be ported),
    • when it is complete (doc included).
  • Add your commits here (no force push)
  • All commits you push must compile. You can comment the remaining part of the the file to push a partial commit, but in that case you don't tick the :white_check_mark: box

Tasks:

  • Use the graph of MC files with live info about this PR in order to pick your next task (the dependency graph is generated by this branch which is slightly broken to maximize parallelization from where we stand)
    • blue nodes are taken by someone :construction:
    • green nodes are ported
      • solid green background means finished
      • yellow background mean compiles :white_check_mark:
  • A file containing no Structure and no Canonical should just work and requires no doc update.
  • A file with Canonical but no Structure requires using HB.instance instead but no doc update.
  • A file containing Structure require complete porting and doc update. Note that only structures with carriers of type Type should be ported in this pass.

Nix CI is broken:

error: value is a list while a set was expected, at /home/runner/work/math-comp/math-comp/default.nix:13:1

gares avatar Jun 10 '21 09:06 gares

@CohenCyril is this gitlab CI pipeline a new thing?

gares avatar Jul 22 '21 17:07 gares

@CohenCyril @pi8027 can you check if the recent locking in rat helps this example: https://github.com/math-comp/math-comp/pull/733/commits/5e84326f5a6759b1d227f066088988e39e8538ff I suspect it just gets slowed in this branch, but that it is already problematic.

gares avatar Nov 15 '21 11:11 gares

Here is a squashed and rebase branch: https://github.com/math-comp/math-comp/tree/hierarchy-builder-rebased (but I cannot force push here)

proux01 avatar Apr 21 '22 13:04 proux01

Rebase force pushed, the previous state (before squashing everything) is saved in https://github.com/math-comp/math-comp/tree/hierarchy-builder-before-rebase_2022_05_04

proux01 avatar May 04 '22 13:05 proux01

So, here is the state of the CI:

  • I dropped planB
  • coq-dev is borken on Nix CI (I understand that https://github.com/NixOS/nixpkgs/pull/161977 should fix it)
  • unfortunately coq-dev is also broken on Docker CI since the lower bound for OCaml was bumped without coordinating with the maintainer of Docker images (https://coq.zulipchat.com/#narrow/stream/237656-Coq-devs-.26-plugin-devs/topic/.3E.3D.204.2E09.20and.20opam/near/280985366) hopefully, this will be fixed soon
  • reverse dependencies not ported yet
    • analysis
    • deriving
    • extructures
  • other reverse dependencies are working out of the box or with an overlay (c.f. list of overlays at bottom of top PR description):

    • autosubst
    • bigenough

Out of curiosity, how are compilation times affected?

ejgallego avatar May 19 '22 09:05 ejgallego

Last figure I remember was nearly a factor two but @gares would know better.

proux01 avatar May 19 '22 09:05 proux01

So, here is the state of the CI:

  • Coq master seems fine thanks to @CohenCyril 's branch (https://github.com/NixOS/nixpkgs/pull/173112)
  • only remaining broken reverse dependencies are:
    • analysis
    • deriving which uses universe polymorphism (c.f. https://github.com/proux01/deriving/blob/48f613b98bfe8d130431c00bac4fefa1e54576be/theories/base.v#L980-L982 ) not yet implemented in coq-elpi
    • extructures which requires deriving

proux01 avatar May 24 '22 09:05 proux01

Last figure I remember was nearly a factor two but @gares would know better.

A 2x increase in compilation time seems a bit surprising (and maybe worrying) . In particular, the amount of time spent in HB code should be just a small fraction of the compilation time.

Isn't that suspicious? What is the main bottleneck here.

I think that Coq really needs something like HB, but if users are gonna get a 2x slowdown from it I'm not sure it is ready until it is more optimized.

ejgallego avatar Jun 14 '22 15:06 ejgallego

The difference is that structures are more regular than before, and less manual tweaks. The time spent in HB commands is negligible, or close to so. The code generated is more likely to trigger bad behavior in conversion heuristics. But so far every time I did investigate a little change here or there would change the cost of a few lines of 100x, so I'm not scared, it is just about spending time on it. And for now the (little) energy is in cover the whole ssrnum (not far, but not there yet).

gares avatar Jun 14 '22 20:06 gares

@CohenCyril you can now delete yout hb-ssrnum branch as it is integrated here

As a consequence, we had to drop support for Coq 8.13 and 8.14, this now only works with:

  • Coq 8.15 with HB master branch
  • Coq 8.16+rc1 with HB master branch
  • Coq master with HB coq-master branch

proux01 avatar Jul 22 '22 11:07 proux01

can we give planB another try? (I'm too bad at nix to bring it back)

gares avatar Aug 27 '22 20:08 gares

can we give planB another try? (I'm too bad at nix to bring it back)

@CohenCyril do you remember how to set this up in Nix CI? (I probably won't have time to look at it anytime soon)

proux01 avatar Aug 29 '22 07:08 proux01

@CohenCyril no hurry, but I may need your Nix expertise with the CI here:

  • reglang fails in the CI but I'm not able to reproduce the failure locally, when I type the CI command
NIXPKGS_ALLOW_UNFREE=1 nix-build --no-out-link --argstr bundle "coq-8.15" --argstr job "reglang"

on my machine the thing compiles flawlessly

  • mathcomp-classical and mathcomp-analysis: this works on Analysis CI (https://github.com/math-comp/analysis/pull/698) but not here, in that case I'm able to reproduce locally and it seems Nix is downloading the source of mathcomp (and not mathcomp-analysis) for mathcomp-classical and I don't understand why (I tried adding an overlay for mathcomp-classical but without success)

proux01 avatar Oct 14 '22 11:10 proux01

@CohenCyril timings to compile OddOrder (make -j1 on my laptop):

  • without semirings: 2074.59user 18.59system 35:21.32elapsed
  • with semirings: 2209.54user 13.78system 37:09.35elapsed

So, that's about 6% slower.
