  • Plenary discussion items
    • PMIx ABI (IAWG/Ken ~ 20 min)
    • PMIx Publish / Lookup (IAWG/Dave ~ 30 min)
      • TODO: ADD DAVE SLIDES
      • Working PR: https://github.com/pmix/pmix-standard/pull/398
      • Discuss issues related to Publish/Lookup
        • Publish takes directives and info in same list, but issue if it is an unrecognized directive this could cause confusion/mistakenly assume as info key
          • Option1: Introduce new API that separates params
          • Option2: Create new directive to flag items to be published, but not solve backward compat
          • Option3: document and add restrictions in spec (no API changes)
          • Option4: do nothing
        • publish/lookup supports multiple ranges
          • validity of publishing same key twice on the same range (WG will look more into it, it is believed to be illegal code with undefined behavior)
          • Group prefers solution where LOOKUP queries only the range it is given (i.e., to be visible, the PUBLISH must target the same range). No ‘inheritance’ of published items. The same key may be published on different range
