Notes

  • Review ASC-Q4-2020 agenda
  • Splitting ASC Meetings across 2 days
    • We split the day between voting and non-voting already, can we split them across days
    • Also gives us the opportunity for a quick follow on vote after a request for minor changes from a PR
    • Easier to schedule and find a time slot, especially to accommodate more time zones
    • Initial idea is to push the start of the call back to 10am CT. Based on Doodle poll, Tues/Thurs are the best days for people currently
    • Question: is there a plan to hopefully get back to a face-to-face? Or go fully virtual going forward?
      • Currently the hope is to get back face-to-face, but that is always open to discussion and current events
  • Governance PR
    • https://github.com/pmix/governance/pull/18
      • Intent is to formalize process for the minor changes scenario, under General voting rules (Sect. 1.1.5) see PDF example in PR
      • Intent being to take feedback during a multiday meeting and allow for a "revision exception vote" that would only review those minor changes and ticket can proceed as those edits were in place when ticket was posed for the meeting.
      • Comments:
        • "The review period deadline" in place of “two-week period”
        • "...regular vote may…"
        • Should account for attendance at 1st but not 2nd day, with absence from second day being an "abstain" for 2nd day.
        • Looks like change is needed for negative and positive sides of voting text in doc
    • https://github.com/pmix/governance/pull/17
      • Intent is to be more precise about review period regarding readings and vote items (~4 weeks in advance of meeting, ~2 weeks for community to read/freeze before meeting)
  • Call for Officers
    • Nominations are open. Send the Chairs an email with any nominations
  • Doodle for 2021 meetings
  • PMIx V4 Discussion
    • Getting feedback from the community and integrating changes currently
    • Revising fabrics chapter based on feedback from HPE
    • Not major changes/feedback; need to implement some things in OpenPMIx before adding the changes to the document. Approximately a week or two impact.
    • Open Pull Requests for V5 can rebase on top of the current V4 master. If they don’t touch the fabric chapter or python bindings, then it should be OK.
    • Question about creating pmix-v4rc2, plan to wait a little for more changes to land.
    • Look at pmix-v4rc1, to include fabrics chapter to give input to Ralph
  • Working Group Updates
    • Slicing/Grouping of functionality
      • Moved meeting times to Thursdays at 11am CT/9am PT
      • Working on changes for integration of use-cases into standard, and format of bringing that as chapters/sections/etc. Intent to bring draft at ASC meeting to get feedback on presentation, or if should be separate document.
      • Josh introduced macros/hooks to bring in the examples into LaTeX source for examples/code
    • Storage
      • Working on OpenPMIx code for handling storage queries. Specifically working on Lustre and virtual filesystem plugin to answer queries for lustre and generic filesystems, respectively. The VFS plugin is essentially a wrapper around statfs to provide some metadata and responses to queries
      • Planning to loop back around to Lustre-specific stats, currently returns non-supported
      • Put together a PR for the proposal, please provide feedback. Have 1 week until the freeze. Don’t expect any conflicts with V4 changes.
    • Dynamic workflows
      • Working on running workflows on Aurora, mOS configurability for jobs via PMIx. How can use PRRTE/PMIx for their configurations to run dynamic workflows
      • Working on having cgroup config and mOS
      • Had several tech talks from different workflow project and related efforts on dynamic/configurable efforts w/ PMIx
    • Implementation agnostic document
      • Looking at comments that Martin gave on the Ch2 PR. Going through and evaluating them for what applies today and what could apply in the future. Trying to keep up with V4 changes, and resolve conflicts.
      • Dave to push changes from recent meeting to PR before freeze
      • Some discussion around adding language to put/get/fence protocols. Mostly already got added into V4.
  • Next ASC meeting is Oct. 1
