4.0.x

  • Schedule: No schedule for v4.0.8 yet
  • Winding down v4.0.x, and after v5.0.x will stop
  • Really only want small changes reported by users.
  • Otherwise, point users to v4.1.x release.
  • New libnbc large payload fix, IBM would like to take

v4.1.x

  • Schedule: Shooting for v4.1.3 end of March/Q1.
    • v4.1.3rc1 this week.
  • No other update.

Read the Docs

  • merged to master last night.

  • Jeff sent email, and will either put into the wiki or in docs themselves

  • Jeff shared https://docs.open-mpi.org/

    • This will be for v5.0.0 and later
    • Links to older docs for v4.1.x and earlier

  • Also a mobile rendering

  • Think the docs configury is done.

    • If issues, slack or email devel

  • Tons of stuff that is ready, but lots of places

  • Thanks to Harumi for converting all of the man-pages

    • They look great!
    • They are cross-referenced now.

  • For developer, when you git clone, you'll now get a docs/ directory

    • There's an RST guide under developer's guide.

  • Now when you push a PR, there's a details link under the Read-the-docs CI under your PR, for you to preview that PR.

  • This is true for master and will be in a few weeks for v5.0.x release branches.

  • Going to let this soak a while on master, but hope to bring to v5.0.x after a bit more testing on master.

  • USES branch names, so this may be a driver to change master to main.

    • Branch name is in URL so might want to do this sooner before others cache urls.

  • Official Tarballs will have html and man-pages pre-built

  • Developers will need to install sphinx to generate html and man-pages.

    • Open MPI Developers guide has a page on how to install sphinx.
    • uses sphinx-build, and (like Make) it's stateful and only rebuilds changes.

  • Just open build/index.html locally in browser.

  • When you git clone, there IS not build directory. It can take 3-5 minutes to build build directory.

    • But if you want you can just rm -rf build.

  • When doing code changes PR against master, Good to do both Doc updates AND code changes in same PR,

    • But if you

  • What's the behavior if you don't have sphinx installed?

    • Configure will just skip building the docs.
    • BUT in this state, you won't be able to do make dist

  • Amazon is calling make dist in CI.

    • so CI should be covered.
    • This will test and fail CI if error in docs

v5.0.x

  • Build v5.0.0rc3 this morning. Build is done, should post and email later this morning.
  • Using New ompi-schizo in prrte.
