CCPP Framework Meeting Minutes 2020 09 10

Agenda

• cap_gen.py progress
• help with diagnostics
• transition to cap_gen.py
• other business

cap_gen.py progress

• Implemented ccpp-table-properties
• Improved at least one error message when comparing Fortran to metadata
• Have not added dependencies to database yet
• PR now or in a few days (when database is updated)?

Diagnostics UI proposal

• For CCPP (in)(out) variables, add a new metadata property, diagnostic_name.
• Support substitutions such as ${process} and ${scheme_name}?
• For non interface variables, allow a diagnostic field in ccpp-table-properties section?

Transition to cap_gen.py

• DTC timeline and resource chart (https://docs.google.com/spreadsheets/d/1XbSF1ejYcPMrVtZtk1OSiMX-vI5srLkwEUhyAirGr8k/edit?usp=sharing)
• things that need to happen for transitioning UFS to cap_gen.py (https://docs.google.com/document/d/1M3mCO3ESR9OJqLyUbQf-ahJtmfmGKilZlWaBTxsfMRk/edit?usp=sharing)
• (from last week) Xia working on assumed-size array declarations
  • several test failures and crashes
  • Dom needs to get started on this, use full compiler debug flags
• Julie ran into issues when using the new (?) cap_gen.py Fortran parser: dimension "n+1" and new [ccpp-table-properties]
  • Steve provided a fix for this
• Ligia and Grant started working on the consolidation of standard names; comparing standard names in GFS_typedefs.meta with CF convention, dictionary of standard names, ... - https://docs.google.com/spreadsheets/d/1kWDC7_2sagm-PTP_tXaGyI3O3sJFK8FY9FElQbb6V3o/edit#gid=613941307

Other business

• (from last week) We need a distribution list for CCPP updates (self signup) - a classic listserv. Do we have one that we can use?
  • We can request a google group via NCAR - what's a good name? ccpp@... ? ccpp-updates@... ? ccpp-announce@... ? ccpp-developers@... ? --> ccpp-announce@...
• Steve busy with NOAA Hurricane Supplemental work this month; need to help Julie to solve her cap_gen.py problems
  • Can Dom help to get the new [ccpp-table-properties] in and fix the n+1 issue? Tag up with Steve Sep 8 or later
