MAPL 2.39.0

[mathomp4]

This is a minor release of MAPL with new features and fixes. The new features are:

• Added minimal support for NetCDF "groups".
• New feature to allow for single component testing as code is refactored
• Added module to process datetime strings from NetCDF to ESMF_Time and ESMF_TimeInterval variables and vice versa

Most of these features are for internal development at the moment.

Also some fixes were made:

• READ_RESTART_BY_FACE has been fixed and now can read restarts from full CS grids as well as restarts that have been separated by face via WRITE_RESTART_BY_FACE. The current implementation requires that both num_readers and num_writers must be multiple of 6.
• 'config.py' has been fixed. python3 requires // for integer divides.

All testing with GEOSgcm shows this to be zero-diff to MAPL 2.38

From CHANGELOG.md

Added

• Added minimal support for NetCDF "groups". getvar* can now optionally specify a group_name and the data will be returned from the named group rather than the default group.

• New feature to allow for single component testing as code is refactored

  • Created Comp_Testing_Driver.F90 in Apps
  • Created subset_fields.py to grab a subset of columns
  • Created shell script to perform subsetting, run the driver, and evaluate differences
  • Instructions for use can be viewed under Apps/Comp_Testing_Info.md

• Added module to process datetime strings from NetCDF to ESMF_Time and ESMF_TimeInterval variables and vice versa

Fixed

• READ_RESTART_BY_FACE has been fixed and now can read restarts from full CS grids as well as restarts that have been separated by face via WRITE_RESTART_BY_FACE. The current implementation requires that both num_readers and num_writers must be multiple of 6.
• 'config.py' has been fixed. python3 requires // for integer divides.
