Meeting notes

• Diagnostic metadata (#695)
  • Courtney to remove hardcoded standard name length limit and potentially ping Dom for re-review
• Codee fortran (#707)
  • Needs review from everyone
• New test to demonstrate GNU failure (#689)
  • Test will pass when fix is in - fix TBD
  • Courtney to reach out to Steve for design help with passing parent DDTs into the suite caps
• Dom has physics PR
  • Wraps MPI broadcast (mpiutil.F90)
  • Error handling is complicated - passing error flag & message all the way down and then do an if after the broadcast (OR use CHECKMPI)
    • Aborting in scheme might not abort all other components
    • Walking back also gives you a trace of your error (though compilers can do this now)
    • Perhaps we should fix ALL non-compliant code first (“stop”s in ccpp-physics, f77 files, etc) - Michael to add that to the DTC group meeting agenda (perhaps someone can work on this)
      • Dom - maybe a hackathon to get some of these through all at once (the PR pipeline is really slow asynchronously right now)
