CCPP Framework Meeting Minutes 2020 10 27

Agenda

• optional arguments
• cap_gen.py progress
• transition to cap_gen.py
• other business

Optional arguments

• used quite a bit in WRF and MPAS, but not correctly
• we would like to make it a requirement to not use optional arguments in CCPP
  • problematic to code up when auto-generating code
• ok with Dave, will get rid of it
• Dom will clean up existing schemes in ccpp-physics
• use active attribute and assumed-size arrays instead

Error reporting

• WRF/MPAS physics report back indices of grid points that have bad data etc
• does this work with assumed-size arrays (i.e. does the array run from 1 to X or from the correct lower to upper bound)?
• our roadmap includes implementing improved error handling using a tool that Steve developed (previously we looked at marble, but that didn't do everything we wanted it to)

Transition to cap_gen.py

• Things that need to happen for transitioning UFS to cap_gen.py (https://docs.google.com/document/d/1M3mCO3ESR9OJqLyUbQf-ahJtmfmGKilZlWaBTxsfMRk/edit?usp=sharing)
• (from almost eight weeks ago) Xia working on assumed-size array declarations, Dom still didn't start working on this
