Other information

In the context of MOM6 IO, notes from @uramirez8707:

The collective netcdf writes + modern diag_manger will improve your performance
without requiring changes to the I/O layout and dealing with distributed files.
https://github.com/NOAA-GFDL/FMS/blob/main/diag_manager/diag_yaml_format.md#7-improving-performance-at-high-resolutions

Unfortunately, there are several pieces that need to come together:

1. FMS must be compiled with the -DWITH_YAML option in cmake
2. Set diag_manager_nml :: use_modern_diag = .True.
   https://github.com/NOAA-GFDL/FMS/blob/99fcd2f64352a9ad3d84dd8a96c3d5b25a0caf56/diag_manager/diag_data.F90#L391
3. The diag table must be converted to yaml. This tool can be used to do the conversion: https://github.com/NOAA-GFDL/fms_yaml_tools
4. Add the use_collective_writes: True key to all of the domain decomposed diag files.

I recommend doing 1-3 and making sure the diag manager is working correctly before moving on to #4.
