Meeting notes

• Steve’s new kinds PR (#719) needs a review from everyone

  • Cheryl will review by confirming it fixes her problem
  • #713 now closed (Jesse’s original implementation)

• Check (but not fix) Fortran format in GitHub actions #717

  • Michael K and Courtney to review

• Draft PR on ddts (gnu failure)

  • Keeping it open so we can bring in the test with the fix
  • Courtney still working on the fix, got some feedback from Steve, Dom, Dustin this week on how to proceed

• DRAFT FOR DOM (#718)

  • Contains Dustin’s mods to get things to work in the SCM, Dom can start getting it into NEPTUNE
  • Contains some hacks as well

Backlog triage

• Metadata to indicate input data source (#413)
  • SIMA has a workaround on the host side
  • Dom has concerns about the complexity
  • Michael closing as “won’t fix”
• Add optional metadata fields for constituent implementation (#461)
  • Still needed on SIMA side, but unclear of design
• Add new errmsg length constant to ccpp_kinds (#466)
  • Want to use a parameter instead of just hardcoding to 512
  • Maybe instead we just need a check in the metadata parser to prevent specifying the length (of errmsg) in a scheme
    • That’s what we’ll do - Mike closing this one and we’ll open a new issue
• Need plan for implementing time-split and process split physics in capgen (#467)
  • Dustin: Grant has a PR to move to process split (applying tendencies) - still desired
  • Mike added “post-capgen-unification” label
• Update capgen testing #471
  • Closing due to Dom’s Codee work and Michael W’s testing refactor
