Discussed Topics

• Timeline and blockers for the next release branch.
  • The community is biased toward branching off only after main branch is feature-complete for the next release
  • The original timeline was before SC 2024 in September.
• Script wrapper, see https://github.com/open-mpi/ompi/issues/12609
  • Jeff suggested adding a test to catch this edge case.
• Big count https://github.com/open-mpi/ompi/pull/12621
  • Close to merge. Need a final review.
  • Beside this change we also need to modify the datatype engine to support large count.
• json parser https://github.com/open-mpi/ompi/pull/12531
  • Ralph brought up a problem with --enable-visibility=no which will expose more symbols. Wenduo will check the current state of the symbols with visibility disabled.
• acoll https://github.com/open-mpi/ompi/pull/12484
  • Need an owner file
  • Need to remove standalone license file
• Require C11 (needed for https://github.com/open-mpi/ompi/pull/12658)
  • Consensus is that C11 should be enforced for v6.0.x
