v4.1.x

• v4.1.x Issues; v4.1.x Questions
  • 12005, Luke: maybe missing memory barrier, awaiting reproducer, likely to affect main, and v5.0.x
• v4.1.x Open PRs
• Next release end of Q1.

v5.0.x

• New issues since v5.0.1
  • 12233 Fixed in main
  • Eror handler issue, fixed in PRRTE
  • Indexed types slow on IB, probably a feature for a later release, being worked on
• v5.0.x Open PRs
  • 12135, awaiting review on main, then good to merge
• v5.0.x Issues; v5.0.x Questions
  • 12090 Check if this was ported over

Main branch

• Main Issues <1month old
  • 12195, fixed in pmix, can be closed after advancing ptrs
• Main Issues 1-3months old
  • Lots of MacOS fixes in, need to update and close
• Older Main issues
  • 10988 will sync up with IBM on reproducer
• Main PRs

Additional Agenda Items

• Maybe this? Issue 12228 "Proposal: provide mpiacc wrapper script"

Likely a moot point - need Gonzalo to provide a clearer justification and how-to for this.

• Discuss the MPI4PY PR and advancing the prrte/pmix shas to fix the regression on main introduced by the last sha advance

Will advance ptrs, should be good to go then.

Misc.

• Moving forward we'll close issues which haven't received user responses in a while. Using bots to remove tagged issues with "awatting user info". Look into 1 or 2

TODO

• Need to discuss MPI 4.1
• Need to discuss MPI 4.0
• Discuss set v5.0.2 timeline
• Discuss v5.1.x feature list and timeline
