Meeting notes

CCPP Framework

• #622 - constituent index lookup
  • Needs courtney approval; she will do that today
• #637 - differing source and module name
  • Courtney to review
• Fortran_to_metadata script has issues with constituent properties ddt
  • Fix included in #644 (which also needs a Courtney review)
• Current intel compiler does not allow >255 subset arguments
  • Dustin to try Courtney’s fix, then they’ll go from there
• Testing refactor #612
  • Considering cleaning up command line interface tests (fewer of these)
  • Considering changing whether we return a comma-seperated list (current) or a newline-separated list (proposed)
    • Dom agrees that breaking into multiple lines works best
    • Michael to open a discussion
• DDT subfields in group caps (#640)
  • Builds on top of #637 - will come out of draft when that one is merged

Standard Names

• CCPPStandardNames renamed to ESMStandardNames!
• Continued work on https://github.com/ESCOMP/ESMStandardNames/pull/87
• Michael K reached out to Ann Tsay & hasn’t heard back yet
• Jesse chatted with Steve Goldhaber - NorESM is planning to adopt CCPP
  • Will be >1 year before they start
  • Should add someone on governance (maybe Steve!)

Discussion

• Dom - cleaning up extra flags in ccpp-physics; will work with Michael W
  • May have impacts to the framework
• Next week will be a standard names meeting
