[2024.03] - 2024-08-22

Known Issues

Diag Manager Rewrite: See below for known output file differences regarding the new diag manager. The new diag_manager is disabled by default, so this 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.

Added

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)

Changed

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)

Fixed

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)

Removed

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)

[2024.02] - 2024-07-11

Known Issues

Diag Manager Rewrite: See below for known output file differences regarding the new diag manager. The new diag_manager is disabled by default, so this 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.

Added

TIME_INTERP: Enables use of verbose option in time_interp_external2 calls from data_override. The option is enabled in data_override_nml by setting debug_data_override to true. (#1516)
COUPLER: Adds optional argument to coupler_types_send_data routine that contains the return statuses for any calls made to the diag_manager's send_data routine. (#1530)
MPP: Adds a separate error log file warnfile.<root pe num>.out that only holds output from any mpp_error calls made during a run (#1544)

Changed

DIAG_MANAGER: The diag_field_log.out output file of all registered fields will now include the PE number of the root PE at the time of writing (ie. diag_field_log.out.0). This is to prevent overwritting the file in cases where the root PE may change. (#1497)

Fixed

CMAKE: Fixes real kind flags being overwritten when using the Debug release type (#1532)
HORIZ_INTERP: Fixes allocation issues when using method-specific horiz_interp_new routines (such as horiz_interp_bilinear_new) by setting is_allocated and the method_type during initialization for each method. (#1538)

[2024.01.02] - 2024-06-14

Known Issues

Diag Manager Rewrite:
- Expected output file changes:
  - If the model run time is less than the output frequency, old diag_manager would write a specific value (9.96921e+36). The new diag_manager will not, so only fill values will be present.
  - A scalar_axis dimension will not be added to scalar variables
  - The average_* variables will no longer be added as they are non-standard conventions
  - Attributes added via diag_field_add_attributes in the old code were saved as NF90_FLOAT regardless of precision, but will now be written as the precision that is passed in
  - Subregional output will have a global attribute is_subregional = True set for non-global history files.
  - The grid_type and grid_tile global attributes will no longer be added for all files, and some differences may be seen in the exact order of the associated_files attribute
DIAG_MANAGER: When using the do_diag_field_log nml option, the output log file may be ovewritten if using a multiple root pe's
BUILD(HDF5): HDF5 version 1.14.3 generates floating point exceptions, and will cause errors if FMS is built with FPE traps enabled.
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.

Fixed

DIAG_MANAGER: Fixes incorrect dates being appended to static file names

Changed

FMS2_IO: Changed register_unlimited_compressed_axis to use a collective gather rather than send and recieves to improve efficiency when reading in iceberg restarts.

Fixed

[2024.01] - 2024-05-03

Known Issues

Diag Manager Rewrite:
- If two empty files are present in the diag_table.yaml file the code will crash with a allocation error (#1506)
- Setting an output frequency of '0 days' does not work as expected and may cause an error stating a time_step has been skipped (#1502)
- The flush_nc_files and mix_snapshot_average_fields nml options are not yet functional. The mix_snapshot_average_fields option is planned to be deprecated (for the rewritten diag_manager only).
- Expected output file changes:
  - If the model run time is less than the output frequency, old diag_manager would write a specific value (9.96921e+36). The new diag_manager will not, so only fill values will be present.

TESTS: test_mpp_gatscat.F90 fails to compile with the Intel Oneapi 2024.01's version of ifort
BUILD(HDF5): HDF5 version 1.14.3 generates floating point exceptions, and will cause errors if FMS is built with FPE traps enabled.

Added

DIAG_MANAGER: The diag manager has been rewritten with a object oriented design. The old diag_manager code has been kept intact and will be used by default. The rewritten diag manager can be enabled via use_modern_diag = .true. to your diag_manager_nml. New features include:
- Self-describing YAML formatting for diag_table's
- Allows 4d variables
- Support defining subregions with indices
- More flexibility when adding metadata and defining output frequency
FMS2_IO: Adds support for collective parallel reads to improve model startup time. The collective reads are disabled by default and enabled via the use_collective flag in netcdf_io_mod.
DATA_OVERRIDE: Adds option to use multiple data files for one field within data_override in order to use annual data files in yearly runs without having to append/prepend timesteps from previous and next year. With the legacy data_table, filenames can be set in order and separated with : ie. prev_year.nc:curr_year.nc:next_year.nc. With the data_table.yaml format, the key is_multi_file enables the functionality and prev_file_name and next_file_name sets the file paths.
INTERPOLATOR: Adds support for yearly/annual data
DATA_OVERRIDE: Adds support for monotonically decreasing arrays for nearest_index, axis_edges, horiz_interp(bilinear), and data_override (#1388)
DOCS: Add documentation for the exchange grid (xgrid_mod) and update the contribution guide to add a section on code reviews
MPP: MPI sub-communicators for domains are now accessible via mpp_get_domain_tile_commid and mpp_get_domain_commid in mpp_domains_mod

Changed

DATA_OVERRIDE: Changes behavior to crash if both data_table and data_table.yaml are present and adds error checking when reading in yaml files
FIELD_MANAGER: Changes behavior to crash if both field_table and field_table.yaml are present as well as adds a namelist flag (use_field_table_yaml) to enable support for the yaml input.

Fixed

DATA_OVERRIDE: Fixes allocation error with scalar routine and replaces pointers with allocatables
INTERPOLATOR: Increase max string size for file paths
AXIS_UTILS: Improves performance of nearest_index routine
CMAKE: Fixes macOS linking issues with OpenMP

[2023.04] - 2023-12-04

Known Issues

GCC 9 and below as well as GCC 11.1.0 are unsupported due to compilation issues. See prior releases for more details.
NO_QUAD_PRECISION macro is no longer set by FMS, the ENABLE_QUAD_PRECISION macro has replaced prior usage of NO_QUAD_PRECISION. -DENABLE_QUAD_PRECISION should be set if quad precision is to be used, otherwise FMS will not use quad precision reals where applicable.

Added

DATA_OVERRIDE: A new namelist flag use_data_table_yaml has been added to enable usage of the yaml format data_override tables. This allows an executable built with yaml support be able to accept either format.

Changed

RESERVED KEYWORD CHANGES: Various routines in FMS have been updated to not use fortran keywords for variable names. The names changed were: data, unit, and value. This may affect usage of external code if argument names are explicitly used. Only required arguement names were changed to mitigate any breaking changes.
TESTS: Changes the testing scripts to allow for the MPI_LAUNCHER environment variable override to work with any provided arguments.

Fixed

CMAKE: Fixed build issue with CMake where precision default flags were being overwritten when using GNU and MPICH.
AUTOTOOLS: Fixes issue affecting installs where the global libFMS.F90 module was not being installed correctly and adds post-install message.
DIAG_MANAGER: Fixes issue with incorrect start_time functionality (from the 2023.02.01 patch)

[2023.03] - 2023-10-27

Known Issues

GCC 9 and below as well as GCC 11.1.0 are unsupported due to compilation issues. See prior releases for more details.
NO_QUAD_PRECISION macro is no longer set by FMS, the ENABLE_QUAD_PRECISION macro has replaced prior usage of NO_QUAD_PRECISION. -DENABLE_QUAD_PRECISION should be set if quad precision is to be used, otherwise FMS will not use quad precision reals where applicable.

Added

UNIT_TESTS: New unit tests have been created or and existing ones expanded on for any modules utilizing mixed precision support.

Changed

MIXED PRECISION: Most subroutines and functions in FMS have been updated to simultaneously accept both 4 byte and 8 byte reals as arguments. This deprecates the --enable-mixed-mode option, which enabled similar functionality but was limited to certain directories and was not enabled by default. To facilitate easier testing of these code changes, the CMake precision options for default real size were left in (along with an equivalent --disable-r8-default flag for autotools). The resulting libraries will support mixed-precision real kinds regardless of default real size. It should also be noted that many routines that accept real arguments have been moved to include files along with headers in order to be compiled with both kinds. Most module level variables were explicitly declared as r8_kind for these updates.
Some type/module changes were made to facilitate mixed precision support. They are intended to have minimal impact to other codebases:
- COUPLER_TYPES: In coupler_types.F90, coupler_nd_field_type and coupler_nd_values_type have been renamed to indicate real kind value: coupler_nd_real4/8_field_type and coupler_nd_real4/8_values_type. The bc field within coupler_nd_bc_type was modified to use r8_kind within the value and field types, and an additional field added bc_r4 to use r4_kind values.
- TRIDIAGONAL: Module state between r4 and r8 calls are distinct (ie. subsequent calls will only be affected by calls of the same precision). This behaviour can be changed via the save_both_kinds optional argument to tri_invert.
CODE_STYLE: has been updated to reflect the formatting used for the mixed precision support updates.

Fixed

DIAG_MANAGER: Tile number (ie. tileX) will now be added to filenames for sub-regional diagnostics.
MPP: Bug affecting non-intel compilers coming from uninitialized pointer in the nest_domain_type
MPP: Bug fix for unallocated field causing seg faults in mpp_check_field
FMS2_IO: Fixed segfault occuring from use of cray pointer remapping along with mpp_scatter/gather
TEST_FMS: Added various fixes for different compilers within test programs for fms2_io, mpp, diag_manager, parser, and sat_vapor_pres.
INTERPOLATOR: Deallocates fields in the type that were previously left out in interpolator_end

Removed

CPP MACROS:
- no_4byte_reals was removed and will not set any additional macros if used. no_8byte_integers is still functional.
- NO_QUAD_PRECISION was removed. It was conditionally set if ENABLE_QUAD_PRECISION was undefined. ENABLE_QUAD_PRECISION should be used in model components instead (logic is flipped)
- use_netCDF was set by autotools previously but wasn't consistently used in the code. FMS should always be compiled with netcdf installed so this was removed with the exception of its use in deprecated IO modules.
DRIFTERS: The drifters subdirectory has been deprecated. It will only be compiled if using the -Duse_drifters CPP flag.

Fixed

DIAG_MANAGER: Fixes issue with incorrect start_time functionality

[2023.02] - 2023-07-27

Known Issues

GCC 11.1.0 is unsupported due to compilation issues with select type. The issue is resolved in later GCC releases.
When outputting sub-region diagnostics, the current diag_manager does not add "tileX" to the filename when using a cube sphere. This leads to trouble when trying to combine the files and regrid them (if the region is in two different tiles)
GCC 10 and greater causing io issues when compiled using O2 optimization flags
GNU compilers prior to the GCC 9.0 release are unsupported for this release due to lack of support for the findloc intrinsic function. This will result in an error saying 'findloc' has no IMPLICIT type and can be resolved by compiling with gcc version 9.0 or greater.

Added

MPP/EXCHANGE: Adds association checks before pointer deallocations in mpp includes and xgrid

Changed

LIBFMS: The libFMS.F90 file (module name fms) meant to provide global access has been updated to include 'fms' and it's module/subdirectory name as prefixes for all names. This will only affect external codes that are already using the global module (via use fms) and not individual modules.
MIXED PRECISION: Updates the axis_utils2, horiz_interp, sat_vapor_pressure, and axis_utils subdirectories to support mixed precision real values.
FMS2_IO: Added in mpp_scatter and mpp_gather performance changes from the 2023.01.01 patch. See below for more details.
FMS2_IO: Improved error messages to give more debugging information
FMS_MOD: Changed fms_init to include a system call to set the stack size to unlimited, removed previously added stack size fixes
MONIN_OBUKHOV: Restructures the subroutines in stable_mix interface so that 1d calls the underlying implementation, and 2 and 3d call it on 1d slices of the data as opposed to passing in mismatched arrays.
MPP: Updates from JEDI for ajoint version the mpp halo filling (mpp_do_update_ad.fh), adds checkpoint for forward buffer information.

Fixed

MPP: mpp_broadcast causing an unintended error message due to checking the wrong pe value
MPP: Added workaround for GCC 12 issues causing errors with string lengths in fms2_io
FMS2_IO: Fixed support for 'packed' data when using NF_SHORT variables. Scale_factor and add_offset attributes will now be applied if present.
DOCS: Improved doxygen comments for tranlon, updated deployment action for site
TESTS: Workaround added for ICE coming from mpp_alltoall test with intel 2022.3, and fixes for any test scripts missing input.nml creation. Fixes for mpp/test_global_array failures.
TIME_INTERP: Fixes crashes when calling with a non-existant field
DIAG_MANAGER: Fixes a module dependency issue causing failures during parallel builds
AXIS_UTILS2: Fixes an out of bounds memory index

Removed

FMS_IO/MPP_IO: The two older io modules, fms_io_mod and mpp_io_mod, have been deprecated and will not be compiled by default. If you wish to compile these modules, you must use the -Duse_deprecated_io CPP flag or the --enable-deprecated-io configure option if building with autotools.

[2023.01.01] - 2023-06-06

Changed

FMS2_IO: Performance changes for domain_reads_2d and domain_reads_3d:
- Root pe reads the data
- Uses mpp_scatter to send the data to the other pes
- Added unit tests to test all of the domain_read/domain_write interfaces
FMS2_IO: Performance changes for compressed_writes_1d/2d/3d
- Uses mpp_gather to get data for write
- Added unit tests to test all of the compressed writes interfaces
- Compressed_writes_4d/5d were unchanged
FMS2_IO: Extended mpp_scatter and mpp_gather to work for int8; added a kludge for scatter since the data is assumed to be (x,y,z)

[2023.01] - 2023-04-03

Known Issues

If using GCC 10 or higher as well as MPICH, compilation errors will occur unless -fallow-argument-mismatch is included in the Fortran compiler flags(the flag will now be added automatically if building with autotools or CMake).
GCC 11.1.0 is unsupported due to compilation issues with select type. The issue is resolved in later GCC releases.
When outputting sub-region diagnostics, the current diag_manager does not add "tileX" to the filename when using a cube sphere. This leads to trouble when trying to combine the files and regrid them (if the region is in two different tiles)

Added

DIAG_MANAGER: Added code refactored as part of larger diag_manager rewrite for the send_data routines. The refactored code is disabled by default and enabled by setting use_refactored_send to true in the diag_manager_nml, and should mirror current behaviour.
FMS2_IO: Added the ability to set deflate_level and shuffle netcdf options in fms2_io_nml. Also added functionality for registering dimensions as unlimited compressed.
YAML_PARSER: Added support for emitting multiple tabbed section keys to allow diag manager yaml output

Changed

STRING_UTILS: Extended the string interface in fms_string_utils_mod to accept reals of 4 or 8 kind, as well as 1, 2, and 3 dimensional real arrays
DIAG_MANAGER: Changed the log_diag_field_info routine to allow for specifying seperator
INTERPOLATOR(s): In horiz_interp, amip_interp and interpolator, changed pointers arrays into allocatables

Fixed

TRIDIAGONAL: Added OMP directives to prevent race conditions
DIAG_MANAGER: Added diag_send_data routine to fix class(*) related compiler issues from the refactor update
SAT_VAPOR_PRES_K: Removed implied saves causing issues with class(*) type checking
TIME_INTERP: Fixed naming conflicts between module level and local variables
YAML_PARSER: Fixed typo in variable name, rename variables to avoid fortran keywords

LIBFMS: makes recently added routines available through the global fms module
CMAKE: Adds build option for position independent code
CONSTANTS: Adds macros to load constants for different modeling systems/uses between GFDL, GEOS and GFS. Can be selected in cmake with -DCONSTANTS=<GEOS|GFDL|GFS>

Changed

STRING_UTILS: Refactored string routine definitions from fms_mod and fms2_io_mod to be located in fms_string_utils_mod
CONSTANTS: Makes fmsconstants.F90 contain the constant definitions, with constants_mod refactored to hold the same values

[2021.02] - 2021-05-20

Added

FMS2_IO: Added fms2_io support for boundary condition restarts. register_restart_region_2d and register_restart_region_3d were added to fms2_io’s register_restart_field interface and read_restart_bc and write_restart_bc subroutines were added to read and write boundary conditions restarts. See test_fms/fms2_io/test_bc_restart.F90 for sample usage.
FMS2_IO: Added fms2_io’s version of set_filename_appendix. The string sent in will be appended to the filename of a restart/history file before the *.nc or before *.tile if tile is in the filename.
FMS2_IO: Added workarounds to get fms2_io code working with pgi
COUPLER_TYPES: Added fms2_io’s version of register_restarts_2/3d and CT_restore_state_2/3d to the coupler_type_register_restarts and coupler_type_restore_state interfaces in coupler_types. The fms_io’s versions were renamed as mpp_io_* and both versions may still be used. See test_fms/coupler/test_coupler_*d.F90 for sample usage.
MPP_DOMAINS: Added a subroutine mpp_create_super_grid_domain, which sets the indices of the input domain to match the supergrid domain.
MOSAIC2/GRID2: Added a version of grid.F90 that is suitable for use with fms2_io called grid2.F90, and moved it into the mosaic2 folder along with mosaic2.F90
FMS_MOD: Added grid_init and grid_end calls for use with grid2.F90
TIME_MANAGER: New set_date_gregorian and get_date_gregorian function/subroutine that do not use coded_date and date_to_day arrays are added and set as default. The original get_date_gregorian and set_date_gregorian have been renamed to get_date_gregorian_old and set_date_gregorian_old and can be used by adding old_method=.true. optional argument to set_date and get_date subroutine calls. This is the first step out of three to remove the memory-consuming coded_date and date_to_day arrays from the time_manager_mod.
FMS GLOBAL MODULE: Adds a new module (libFMS.F90) to be used as a global import for all supported routines/types/variables within FMS. Also adds a separate module (fmsconstants.F90) to be used for constant values from constants_mod.

Changed

FMS2_IO: Adds logic so that the domain decomposition variable attribute is only added if the io_layout is not 1,1.
FMS_IO: Moved get_great_circle_algorithm from fms_io to grid2.F90
FMS_IO: Moved routines and submodules that were not IO related to fms_mod ###Removed
DIAG_MANAGER: Removed the variable attributes _FillValue and missing_value from the time_bounds variable to be cf compliant
FV3GFS: Removes the unused fv3gfs directory
MOSAIC/GRID: Removed references in grid.F90 to fms_mod(replaced with mpp_mod direct calls)
MOSAIC/GRID: Moved mosaic/mosaic2.F90 to mosaic2 folder ###Fixed
DIAG_MANAGER: Fixed a bug where the variable type of Time and Time_bounds were different (float vs double) when compiling with 32 bit reals
FMS2_IO: Fixed a bug where the code was crashing when you were trying to read/write scalar variables with the domain decomposed fileobj

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.

[2020.03] - 2020-10-08

Added

FMS2_IO: Adds header_buffer_val to the fms2io namelist which sets the netcdf header size in bytes. The default value is 16kb
FMS2_IO: Adds netcdf_default_format to the fms2io namelist which allows the user to change the netcdf file type. The default value is 64bit.
FMS2_IO: Adds support to read netcdf string global attributes
FMS2_IO: Adds an optional argument to open_file, dont_add_res_to_filename, which indicates that the filename should not be modified (default adds .res to restart file name)
FMS2_IO: Modifies the register_variable_attribute and register_global_attribute interfaces by adding str_len as an argument. This is a workaround to get fms2io to work with PGI because they don't support class () with len=.
FMS2_IO: Adds unit test that tests write_data and read_data when using a domain with a mask table
FMS2_IO: Adds fms2io’s version of get_mosaic_tile_grid
MPP_IO: Adds -Duse_mpp_io compile option for data_override, interpolator, amip_interp, diag_manager, topography, and xgrid to select using mpp_io instead of fms2_io
MPP_INIT: Adds unit tests for routines/functions that are called in mpp_init
CMAKE: A cmake build system has been added with a CI build using cmake

Changed

FMS2_IO: Improves performance of previous release by gathering the domain decomposed data into one global buffer and doing one write rather than doing multiple reads
DATA_OVERRIDE: Changes line in time_interp_external2 to enable 3D overrides

Fixed

DATA_OVERRIDE[2]: Fixes a crash when doing ongrid data_override calls with a domain with halos
DIAG_MANAGER[2]: Fixes an issue where time_bnds were written incorrectly for the last time stamp
DIAG_MANAGER: Regional diagnostics with a mask table now work

[2020.02] - 2020-05-01

Added

FMS2_IO: An fms2_io_nml namelist has been created. It includes the variable ncchksz. This is the replacement for the environment variable NC_BLKSZ set in model run scripts and used by mpp_io. The default value is 64 KB. Any time a file is opened in fms2_io (nf90_open or nf90_create), the optional argument chunksize=ncchksz is passed to the NetCDF library. NetCDF attempts to use this value to control the blocksize utilized for reads and writes of data from the filesystem.
FMS2_IO: Adds support to compute_global_cheksum.inc for real32, assuming the flag -DOVERLOAD_R4 is used when compiling.

Changed

MPP_DOMAINS - nesting: The logic supporting nested domains for mosaic grids has been overhauled and extended. FMS now supports multiple nests and telescoping nests (nest embedded within a nest). The requirement for a nest to lie wholly within a single tile has been relaxed and a first-level nest may cross tile boundaries, but may not contain a tile corner. Communications for two-way nesting have also been improved. The 2019 December Public Release and 2020.02 GFDL Release within the [GFDL_atmos_cubed_sphere] (https://github.com/NOAA-GFDL/GFDL_atmos_cubed_sphere) have been updated and are compatible with this release of FMS.
FMS2_IO: The intent of fileobj is changed from (in) to (inout) in netcdf_restore_state_wrap, restore_domain_state, and netcdf_restore_state because the file object type has a pointer that is being reassigned in one of the routines lower in the call stack.

Deprecated

MPP_DOMAINS - nesting: The initial nesting implementation is no longer supported. Please see the Changed::MPP_DOMAINS sub-entry under.

Removed

GENERAL: References to the macro _ALLOCATABLE have been replaced with “allocatable”, _ALLOCATED has been replaced with “allocated”, and _NULL has been removed. It is now assumed that all compilers support the Fortran 2003 standard. The macros still exist in fms_platforms.h for compatibility within other components.
DIAG_MANAGER: “fms_platform.h” is no longer included in any of the diag_manager routines. Instead, fms_platform_mod is now being use-associated where necessary. This fixes an issue for debuggers not providing correct line numbers.

[2020.01] - 2020-03-13

Added

Adds the modules axis_utils2, mosaic2, and time_interp_external2 that use fms2_io
Adds unit tests for thread affinity in test_fms/affinity
Autotools unit tests are now run with srun, mpirun, or aprun (whichever is present on your system)
fms2_io provides three new derived types, which target the different I/O paradigms used in GFDL GCMs:
- type(FmsNetcdfFile_t) - This type provides a thin wrapper over the netCDF4 library, but allows the user to assign a “pelist” to the file. If a pelist is assigned, only the first rank on the list directly interacts with the netCDF library, and performs broadcasts to relay the information to the rest of the ranks on the list. This derived type also allows the user to perform “compressed” reads/writes and restart variable “registration” (i.e. the ability to store pointers to user-defined/allocated buffers) and reads/writes in a manner similar to the existing calls in fms_io.
- type(FmsNetcdfUnstructuredDomainFile_t) - This type extends the FmsNetcdfFile_t type to support “domain-decomposed” reads/writes on a user defined mpp_domains unstructured grid. Users are required to inform the FMS2_io module which dimensions correspond to the unstructured grid using the appropriate register_axis call before any domain-decomposed reads/writes can be performed.
- type(FmsNetcdfDomainFile_t) - This type extends the FmsNetcdfFile_t type to support “domain-decomposed” reads/writes on a user-defined mpp_domains two-dimensional lon-lat or cubed-sphere grid. Users are required to inform the fms2_io module which dimensions (‘x’ or ‘y’) correspond to the two-dimensional grid using the appropriate register_axis calls before any domain-decomposed reads/writes can be performed.
fms2_io requires the user to manage objects of the types described above. Calls to open_file (close_file) act as constructors (destructors) for each of the objects, and must be explicitly made by the user. Each object must be constructed before any I/O can be performed. Examples describing how to use these new types are available in test_fms/fms2_io
fms2_io treats _FillValue attributes as valid_max or valid_min range specifiers if none of valid_range, valid_min, and valid_max are specified as described in these netcdf conventions

Changed

The diag_manager IO is handled by fms2_io instead of mpp_io. Default behavior assumes that the mpp_io namelist variable is set to cf_compliant = .true.
The user must specify the diagnostic attributes that they want to write to the output files. Example: If there is no units attribute, then the variable metadata will not include units, and it will not automatically add units = “none”.
Calls to register_diag_axis for an X or Y axis that is shifted from the CENTER position need to include the optional argument domain_position and should be equal to EAST or NORTH based on the position relative to the domain. EAST and NORTH are exposed through diag_manager_mod.
Changed the handling of average_T and time_bnds variables so that they are set to values that are sent in and are not manipulated as was the case in mpp_io.
interpolator, xgrid, data_override, and amip_interp now call fms2_io routines
Support for enabling/disabling quad-precision (used in certain calculations) has been changed to a hard on/off switch. Default behavior is quad-precision disabled. To enable, add the following CPP macro -DENABLE_QUAD_PRECISION. This change was necessary to remove guessing at the proper setting via a mix of compiler vendor and system-defined environment variables which resulted in different behaviors on machines unbeknownst to the user.

Deprecated

fms2_io does NOT use the scale_factor, add_offset, or other attributes to manipulate the data. The variable/data is returned to the caller as it appears in the file. All post-read data manipulations should be handled by the caller.

Removed

Removes the use of bats when running unit tests
