2023.01.01

[2023.01.01] - 2023-06-06

Known Issues

• GFORTRAN: 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.

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

[2023.01] - 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
• DOCS: Fixed incorrect serial build instructions
• COMPILER SUPPORT: Fixed compilation errors with Intel's llvm-based compiler and added support for the CMake build. Also fixed mpp_checksum unit test failures with openmpi and nvhpc compilation issues.
• TIME_MANAGER: Fixed an bug from PR #1169 that was causing answer changes in land models

2022.04

[2022.04] - 2022-10-13

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

• FIELD MANAGER: Adds support for reading field tables in the yaml format (field_table.yaml).
  Yaml input only be used if compiled with -Duse_yaml preprocessor flag, otherwise it will default
  to previous behaviour. The converter script to convert current field tables to the new format is
  publicly available here, although the conversions will also be done automatically in FRE.
• FMS2_IO: Adds options to enable data compression and chunking for netcdf output in register_restart_field

Changed

• BUILD: Improves the configuration check for the MPICH/GCC 10+ argument mismatch bug by replacing it with a m4 compile test

Fixed

• Compiler Support: allows for compilation via the Cray/HP CCE compilers by fixing string concatenation compilation errors

2022.01

[2022.01] - 2022-03-25
