Notes

  • Next Meetings / Deadlines
    • PMIx ASC Monthly Meeting: 3/10/2022 (No Feb monthly meeting)
    • PMIX ASC Quarterly Meeting: 2/15/2022 and 2/17/2022
      • Announcement Deadline: Jan. 18, 2022
      • Agenda Finalization: Feb. 1, 2022
  • PMIx v4 Release Update (Ralph/Josh)
    • v4.2 planned for Mid/Late 2022 (as needed)
    • Few errata that may be included in release later this year
    • See comment  in v5 section about having IOF provisional in 4.2
  • PMIx v5 Release Update (Ken/Dave)
    • Intention is to have v5 this year, main remaining item still pending is the ABI topic
    • Next meeting (Jan-2022) is the last meeting for v5 reading (i.e., to have item included in v5)... well, maybe that’s the Q2-2022 meeting.  :-)
    • Discussion on ABI, we would like to have it in v5, but it may be more complicated than anticipated, it may not be necessarily a gating feature.
    • We already have an WIP PR on adding constants, the announce of finalization deadline for v5 will be loosely tied to the progress of this PR.
    • Reminder to Thomas for IOF attributes in standard, possibly pursue as provisional in v4.  Will sync w/ Ralph.
  • Working Group Updates:
    • Implementation agnostic document: Dave Solt
      • Working on preparing the PR for v5 about put/get/query impl. Agnostic
      • Next meeting slated for ABI discussion
    • Tools: Isaías A. Comprés
      • From brainstorming to prototyping and implementation
      • PMIx deeper integration in workload managers
        • Start with Slurm (lead by Ralph)
          • Currently only “mpi” plunging in Slurm
          • Other plugins will be added, such as the “launch” plugin
        • Later on others
          • Flux a high probability with TUM and LLNL
          • Talks with SGE and PBS Pro
      • Malleability prototyping (lead by Isaias)
        • Previous work from Ralph in Open PMIx
        • Deep-Sea project as driver
        • Need to collaborate with Dynamic Workflows WG
        • Collaboration with the MPI Sessions WG
          • As well as MPI Fault Tolerant WG (still forming)
      • Proposal coming in for either 5.0 or 5.1
        • First PR: Early March most likely
    • Dynamic workflows: Justin Wozniak
      • Intent to try and tie PMIx into workflow projects, e.g., ECP’s ExaWorks
  • ABI Update (Ken)
    • https://github.com/pmix/pmix-standard/issues/365 (general issue)
    • TODO: add Ken’s slides
    • Discussion about memory use of key/nspaces; memory reduction of internal openPMIX impl. Is possible without changes, but the current API promotes libraries/end-users being wasteful. This may motivate an API change that does not waste as much memory
    • Announce on a variety of mailing lists to have advice from all stakeholders on this change
    • Meeting time for ABI discussion is Jan. 24th, announcement to follow
  • PMIx Standard Issues/PRs
  • PMIx Governance Issues/PRs
