CCPP Framework Meeting Minutes 2023 06 26

Agenda

Attendees: Michael Kavulich,

PR 463: Support multiple concurrent instances per MPI task
- Merged! 🥳
PR 468: Constituent updates
- Still needs review
- Needs update to resolve merge conflict
Questions from NCAR folks
- is it OK if we pursue containers for ccpp-framework testing
  - No procedural limitations since this is a repo in the NCAR organization
  - Question: why container instead of just using self-hosted runner or GitHub runner directly?
    - container needed for getting specific compilers and environment
      - Base containers available for spack-stack
    - Self-hosted runners may be needed for GPUs
      - Dustin will look into doing this on Cheyenne/Derecho
- In terms of best practices: would it make sense to go for thread-safe physics schemes vs stateless physics schemes?
  - Going stateless will be quite a bit harder for CAM, thread-safe would be easier to achieve

PR 37: Add new cloud standard name rule, and update cloud_area_fraction
- Needs re-review from Grant, but should be ready to merge after that
Issue 39: gravity and the "coordinates" section
PR 40: adding filename for micm
- This needs some more description/explanation
- Follows example of several other standard name variables, so no reason to hold this up for that reason
- Because there may need to be more changes before MICM is fully working, we will convert this to a draft for now.
Issue 41: CCPP metadata file standard name checking tool
Issue 42: Want Github Action to ensure standard names are following character rules
