Day 1: May 9, 2023

Plenary: Event chapter

https://github.com/pmix/pmix-standard/pull/443

Action items:

  • Everyone: Please review the PR.
  • Will be ready for first reading next meeting (23Q3).
  • Error and Event codes share a type and range. So clarify that some calls allow for any integer value but the user should be aware of the predefined Error and Event values when choosing an integer value.

Plenary: Data Pack/Unpack chapter

https://github.com/pmix/pmix-standard/pull/449

We walked through the changes to this chapter:

Open Questions:

  • Implementation agnostic Issues:
    • PMIx_Data_compress/Uncompress might be implementation specific
  • Unclear how memory allocated by PMIx_Data_[un]compress can be freed.
    • The chapter states that the user is responsible to free the memory, but no according function is provided.
    • Shall there be a generic function to free?
  • PMIx_Data_load claims to free pre existing memory
    • Does this actually make sense. Memory might be static
    • Partial unpacking: If not the full content of the buffer was unpacked because it does not fully fit into the provided memory
    • Overall, policy for memory handling will need further discussion

Update on status of the v5 release

  • Approval vote for v5 release candidate passed in Q1 meeting
  • Minor editorial changes added in the meantime
    • Acknowledgement updates

Ready for release

Update on status of the v4.2 release

v4.2rc1 is ready for review

Working groups

  • Client Separation / Implementation Agnostic Document
    • Plan to step into the next chapter
    • Meeting times reversed back to Monday (4pm EST)
  • Tools / Dynamic Workflows
    • A Cancellation request for Allocations might be required
    • Not in the original standard to avoid race conditions

Call for new WGs

  • No new WG were called for this time however, Impl. Agnostic WG finds a lot of things that could be spun to other WGs, E.g., Publish-Subscribe, Data Packing/loading, …
  • Dave will get a list of open topics
  • Each new WG could be short lived and issue focused.
  • Each new WG will require a ‘champion’ to lead the group.

Working time on v4.2 issues and Open PMIx/PMIx Drift

We did not finish, all items discussed compiled in day2 notes for clarity.

Day 2: May 11, 2023
