NOAA-GFDL/FMS: 2020.02

[2020.04] - 2020-12-07 Added DIAG_MANAGER: A namelist flag called use_mpp_io if set to .true. will use mpp_io. The default is .false. and will use fms2_io. DIAG_MANAGER: A check is added before a time axis is registered to check if the time axis is registered as a variable DIAG_MANAGER: A unit test was added to test the optional new_file_freq functionality XGRID: A namelist flag called use_mpp_io if set to .true. will use mpp_io. The default is .false. and will use fms2_io. INTERPOLATOR: A namelist flag called use_mpp_io if set to .true. will use mpp_io. The default is .false. and will use fms2_io. AMIP_INTERP: A namelist flag called use_mpp_io if set to .true. will use mpp_io. The default is .false. and will use fms2_io. TOPOGRAPHY: A namelist flag called use_mpp_io if set to .true. will use mpp_io. The default is .false. and will use fms2_io. DATA_OVERRIDE: A namelist flag called use_mpp_bug if set to .true. will use mpp_io. The default is .false. and will use fms2_io. DATA_OVERRIDE: A namelist flag called reproduce_null_char_bug_flag if set to .true. and fms2_io is being used, it will reproduce the mpp_io bug where the axis bounds were calculated instead of read. The default is .false. A unit test was added to test the functionality of get_grid_version_1 FMS2_IO: A unit test was added to test the functionality of get_valid and is_valid ### Changed The autotools build has been changed to copy each subdirectory module (.mod) files to a common .mod directory located at the top of the source directory. This change simplifies the include path specifications. Use F90 module files for external libraries (MPI and NetCDF) for improved interface checking, thereby removing the reliance on library header include files. ### Removed LIBFMS: The flag -Duse_mpp_io should not be used and will cause a crash LIBFMS: Macros and logic for interfacing to the Flexible File I/O library LIBFMS: Macros for SGI MIPSpro compilers, including: mpp_node function and SGI Irix specific high resolution timer LIBFMS: Macros for IBM AIX compilers LIBFMS: Files in mpp supporting the CRAY SHMEM communications library LIBFMS: Files in mpp for the SGI PSET approach for communication via GSM ### Fixed DATA_OVERRIDE: Fixed a bug in get_grid_version_1 where the variable_size calls were not correct FMS2_IO: Fixed a bug in get_valid where the mpp_broadcast calls were done inside if (root_pe) blocks The fms2_io unit tests were modified so they can work with the AOCC compiler XGRID: Fixed a bug in load_xgrid by checking if a dimension exists before calling get_dimension_size to avoid FATAL: NetCDF: Invalid dimension ID or name crashes ### Tag Commit Hashes 2020.04-alpha1 (2428bb182133b8062432ee1b15974739753ca470) 2020.04-alpha2 (ad9915d83a2f34610cd748fd85889ba1f0f1fc02) 2020.04-alpha3 (e7e48839ab25cc9405abe5d8418e1b6ee6fb2d69) 2020.04-beta1 (6d3ac620423e7ede412e4bb1b36c338775d95193
