Day 2: Jan. 25, 2024: PMIx ASC 24Q1

  • Reading of PMIx Standard PRs up for a Second Vote that have changed:
    • PR 490 Issue 414: ordering & method of specifying procs in collectives clarified
      • No further comments
    • PR 443 Minor edits to the event chapter
      • No further comments
  • Open Discussion
    • Use-Cases in Appendix B of the standard
      • How can we make them more visible
      • They were on the web-page before
      • Some use cases have only list of functionalities APIs/Attributes but no example code
      • Some use cases have example codes
      • Q?: should the appendix B have usage examples in all use-cases, or should it just refer to the PMIx website for actual use cases demonstrators; ATM we tend to prefer solution 2.
      • Some use cases may be missing the required server-side/RM APIs to support the client activities: TODO: review what is missing
      • Some use cases are missing altogether (dynamic spawn, FT, ???)
      • TODO: propose to WG heads to refocus some WG time towards creating the material for the use-cases/website
    • Discussion about walled-garden
    • Few additional remarks related to Use-cases
      • Good to have some symmetry in Std use-case and Impl. examples
        • Main benefit of Std side would be to have easy way of specifying things for RFP (e.g., Support PMIx Use-cases Foo, Bar, Baz)
        • Need to make Impl side example more apparent on website and raise the examples for people to understand and use
      • Missing Use cases in Std
        • Spawn
        • FT
        • Server side aspects (current use cases focused on Client side)
          • Not nec. HOW but, What is expected from the server side (e.g., wire-up from Server perspective)
      • Q: Where should example codes live?  In Standard or in OpenPMIx
        • Suggestion:
          • Std have succinct WHAT info for Use cases
          • Impl have succinct HOW info for Use cases
    • How do we react on HPSF?
      • Wait and see how HPFS will evolve
      • There is no urge to position us right now
