[2024.01.01] - 2024-05-30

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.

Added

  • DIAG_MANAGER: Implements flush_nc_files functionality from legacy diag_manager.

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

  • DIAG_MANAGER: Fixes 0 day output frequencies causing error stating a time_step was skipped. Also adds checks to crash if averaged fields have -1 or 0 day frequencies or if mixing averaged and non-averaged fields in the same file.
  • DIAG_MANAGER: Fixes issue with the weight argument not getting passed through to reduction methods.
  • DIAG_MANAGER: Allocation errors when using two empty files.
  • DIAG_MANAGER: time and time_bnds being larger than expected when running for 1 day and using daily data.
  • DIAG_MANAGER: Allows for mixing static and non-static fields when frequency is 0 days.
  • TESTS: Fixes compile failure with ifort 2024.01 from test_mpp_gatscat.F90.

Removed

  • DIAG_MANAGER: The mix_snapshot_average_fields option is deprecated for the rewritten diag_manager only.
