MAPL 2.53.0

This release of MAPL has a bugfix for an issue discovered by our UFS users. Namely, it fixes a bug when MAPL is used with OpenMP in a certain way such that the correct dimensions for the MPI subdomain could be retrieved from the subgrids where ever needed.

It also updates ExtData so that if files are missing in a sequence the last value will be persisted if one has not chosen exact option

All testing with GEOSgcm shows this to be zero-diff.

---

This version of MAPL was tested with:

• Intel Fortran Classic (ifort) 2021.6.0 and 2021.13
• Intel Fortran (ifx) 2025.0
• GCC 13.2.0 and 14.2.0
• NAG 7.2

The libraries this version of MAPL is currently tested with are below.

• Baselibs 7.27.0
  • netcdf-c 4.9.2
  • netcdf-fortran 4.6.1
  • ESMF 8.7.0 (Note: MAPL only requires 8.6.1 at the moment)
  • GFE 1.16.0
    • gFTL 1.14.0
    • gFTL-shared 1.9.0
    • pFUnit 4.10.0 (optional)
    • fArgParse 1.8.0 (if -DBUILD_WITH_FARGPARSE=YES, default=YES)
    • pFlogger 1.14.0 (if -DBUILD_WITH_PFLOGGER=YES, default=YES)
  • UDUNITS2 2.28.8

Also, if you build with Baselibs and/or -DUSE_F2PY=ON, you should use (at least):

• ESMA_cmake v3.55.0

We recommend most external users set -DUSE_F2PY=OFF

We also require CMake 3.24 or higher.

MAPL 2.52.0

This release of MAPL has many new features and fixes over MAPL 2.52.

Among the new features are:

• Added the ability to read netCDF tile files
• Added a new optional start_date and start_time to control the output window for each History collection. No output will be written before then. If not specified, these default to the beginning of the experiment.
• Added loggers when writing or reading weight files
• Added new option to AGCM.rc overwrite_checkpoint to allow checkpoint files to be overwritten. By default still will not overwrite checkpoints
• The trajectory sampler netCDF output variable location_index_in_iodafile can be turned off, after we add two control variables: use_NWP_1_file and restore_2_obs_vector for users. When set to true, the two options will select only one obs file at each Epoch interval, and will rotate the output field index back to the location vector inthe obs file before generating netCDF output.
• Support splitfield: 1 in HISTORY.rc for trajectory sampler

The fixes include better freeing of MPI communicators (which were accumulating during long runs) and better behavior of calls when NaNs are present.

All testing with GEOS shows this is zero-diff to MAPL 2.51

NOTE: Below you'll see that we are now generally testing MAPL (in CI) with ESMF 8.8.0. At the moment, ESMF 8.8.0 is not required for MAPL 2. It is a requirement for MAPL 3 but we have not yet added any use of ESMF 8.8 specific features in MAPL 2.

MAPL 2.51.0

This release of MAPL has many new updates and changes. Some highlights include:

• Support for the Intel ifx compiler (including in CI)
  • Note that MAPL Unit tests only work with ifx 2025.0, though 2024.2 can work with GEOSgcm
• Allow lat-lon grid factory to detect and use CF compliant lat-lon bounds in a file when making a grid
• Added a call in GenericRefresh to allow GC's refresh method to be called; in support of CICE6 rewind
• Add ability to use an ESMF_CONFIG_FILE environment variable to specify name of file to pass in pre-ESMF_Initialize options to ESMF (see ESMF Docs for allowed flags)
• Added commandline options to checkpoint_benchmark.x and restart_benchmark.x to allow for easier testing of different configurations. Note that the old configuration file style of input is allowed via the --config_file option (which overrides any other command line options)
• Fixed issue of some Baselibs builds appearing to support zstandard. This is not possible due to Baselibs building HDF5 and netCDF as static libraries
• Preliminary support for llvm-flang
  • NOTE: MAPL does not yet work with llvm-flang. But some updates were added here for development testing.
• Trajectory sampler: fix a bug when group_name does not exist in netCDF file and a bug that omitted the first time point
• Fixed a bug where the periodicity around the earth of the lat-lon grid was not being set properly when grid did not span from pole to pole

There are also new build requirements for MAPL 2.51:

• CMake 3.24
• ESMF 8.6.1

All tests show this to be zero-diff to MAPL 2.50
