Release 2024.03 · NOAA-GFDL/FMS

[2024.03] - 2024-08-22

Diag Manager Rewrite: See the previous releases for known output file differences regarding the new diag manager. The new diag_manager is disabled by default, so these differences will only be present if use_modern_diag is set to true in the diag_manager_nml.
BUILD(HDF5): HDF5 version 1.14.3 generates floating point exceptions, and will cause errors if FMS is built with FPE traps enabled. FPE traps are turned on when using the debug target in mkmf.
GCC: version 14.1.0 is unsupported due to a bug with strings that has come up previously in earlier versions. This will be caught by the configure script, but will cause compilation errors if using other build systems.
INTEL: The -check uninit flag for the Intel Oneapi Fortran compiler (ifx) is unsupported due to a bug causing false positives when using external libraries. If using the -check all flag, -check all,nouninit should be used instead.

DATA_OVERRIDE: Adds a namelist flag use_center_grid_points which, if true, enables reading the centroid values from the grid spec for ocean and ice models. This fixes issues with grid files that have longitudes ranges from 0:180 and then -180:0, but will cause answer changes if enabled. (#1566)
DATA_OVERRIDE: Adds support for reading external weight files. Currently only supported for fregrid generated files while using the bilinear interpolation method. Documentation for this feature can be found in data_override/README.md. (#1556)
PLATFORM: Adds two constants FMS_PATH_LEN and FMS_FILE_LEN and uses it across the code for any file path or file name character strings. They default to 1024 and 255 but can also be set by the FMS_MAX_PATH_LEN and FMS_MAX_FILE_LEN CPP macros. (#1567)
CMAKE: Adds Cmake option to support building shared libraries (#1559)

DIAG_MANAGER: Simplifies the diag_table.yaml format by allowing module, reduction, and kind to be set on a file level, with the ability to override for a specific field. (#1545)
FIELD_MANAGER: Updated and refactored the fm_yaml_mod module for a new table format to remove the subparams key. (#1547)
DATA_OVERRIDE: Updates the yaml format to be improve readablity and to be more consistent in key names. Additional documentation for the new format can be found in data_override/README.md. (#1556)

PARSER: Adds error code checks to the yaml parser to prevent code from hanging on invalid yamls (#1563)
PARSER: Adds ability to read in generic blocks to support field_manager updates. (#1519)
CRAY COMPILER SUPPORT: Updated any multi-line string literals to be compatible with the cray compiler. (#1554)

DIAG_MANAGER: Removed diag_table schemas from FMS and moved them to the gfdl_msd_schemas repository, and updates the diag_manager documentation markdowns. (#1543)
