Meeting Notes:

Day 1: May 6, 2025: PMIx ASC 25Q2

  • Release planning
  • Plenary discussion items
    • #41 - Update README.md, https://github.com/pmix/governance/pull/41
    • PMIx-Examples
      • https://pmix-examples.readthedocs.io
      • Misc: Need permissions to transfer to pmix Github org
        • Looks like Ralph/JoshH/JeffS have org admin permissions and can help
      • Q: Level of review for pmix-examples material?
        • Consensus was that do not want lots of formality
        • Possibly have CI checks for reviews on github and for verifications
        • Maybe have N reviews required before merge
        • No need for format voting as not making changes to the Standard
      • Github setups
        • Add an “examples” label and maybe a new “examples” issues template
        • Add CI to check tests/code
      • Examples likely to be good method for driving ASC discussion (see “roadmap” discussion below)
    • Roadmap/planning discussion
      • V6.0 cleanup
        • Triage old issues - cleanout/archive of issues in pmix-standard (possibly revive past items that have been forgotten, or squash as done/not interesting, etc.)
      • Examples for use case
      • Discussion: Interoperability client/server “wire protocol”?
        • Example of singleton detection
        • Possibly have standard wire protocol in project daemons
        • Possibly eliminate client/server incompatibility problem
        • Q: is wire protocol encapsulated in openpmix?
          • Example contrasting point is mpich’s hydra that uses string based wire protocol
          • Questions about status for protocol between client/server (not necessarily inter-daemon itself)
        • Q: How does this differ from cross-version compat?
        • Possibly create an example for client/server interoperability to have better insights on this topic
        • High value item is walk-through PMIx_Init and what is involved in the initialization (env vars for discovery, etc.)
        • If using examples, where should this fit?  Client, Server, other?
          • Will go between client/server library and host server
          • Relates to “minimal server” example
      • Discussion: Standard should be more detailed
        • Example - non-blocking call, text is little loose for before/after in context of threads, need better precision in text.
        • Refinements to text as implementations/examples proceed to help clarify vagueness when encountered.
        • JSC working w/ Partec and encountering implementation items based on Standard and prompting a few items that fit under this category
    • Cancel 25Q2 Day-2 (Thu) b/c full agenda covered
    • Other/Open discussion
    • TODOs
      • Post meeting notes
      • Review v6.0 milestone issues (triage & comment as needed)
      • Look into pmix.org DNS issue (resolved)
      • Migrate pmix-examples => pmix Github Organization
      • Create “examples” label in pmix-standard issues tracker
      • Possibly issue for comments on “wire protocol” / interoperability example
      • Thomas: SPI CY24 report & circulate for any edits/changes, then submit

Day 2: (CANCELLED) May 8, 2025: PMIx ASC 25Q2
