GitHub issues/PRs

CCPP Framework (issues, PRs, discussions)

• #526: Add optional attribute to capgen/prebuild
  • Two proposed solutions, one for capgen and prebuild; this issue is for capgen
  • Reintroduce optional attribute for CCPP physics schemes
  • Schemes test for presence of argument if variable is declared optional in metadata
  • Scheme metadata must have optional if (any) host model uses active other than default (.true.)
  • #529: Draft PR for use of optional attribute in capgen
• #527: Add tests for optional attribute
• #528: Fortran 2008 MPI interface for CCPP framework and CCPP (UFS) physics
  • Incompatibility of MPI communicator type (integer for old MPI, MPI_Comm for MPI F08)
  • Currently talking with CCPP users to check if we need to support both (can do via framework, rather ugly)
  • If only MPI F08, then #523; if both, then #530
• #519: Ready to merge (requires CCPP physics PR as well)
• #525 (merged): Add new test for active attribute with array transformation (variable actions)

Standard names (issues, PRs, discussions)

• #57: Steve Sandbach (UKMO) sent a suggestion, need to check if ok with UFS
• #49: Resolved for now? Create separate sections for different chemical models and describe the names for these models there
