Old/New Issues:

• Doc Issues: https://github.com/open-mpi/ompi/projects/3

  • Some of the smaller issues, we might be able to say that an item is ToBeDone. Note: Sorry we haven't documented this yet.

• PMIX v4.2 async modex issue: https://github.com/openpmix/openpmix/issues/3077 (no progress)

  • Work around: -x PMIX_MCA_gds=hash or enable opal_pmix_collect_all_data
  • Need to up the timeout, fix in OMPI before PMIX_Get, increase timeout as a function of scale with user override.
  • Likely that the original issue is missing an additional variable for async modex. to ompi_pml_base_check_pml
  • New parameter exists for v5.0.x MUST be documented,

• MCA Params issues are biggest issues now - no new updates.

  • https://github.com/openmpi/ompi/issues/11532

  • Plan is to have 2 of the 3 fixes for v5.0.0, 3rd issue can wait for 5.0.x
  • Quincy assigned, working on docs first.
