…OAA-GFDL#1775) * Refactor MPP_GATHER_PELIST_3D_ to implement 3D gathers using the existing MPP_GATHER_1D(V)_ routines, leveraging collective communication instead of manual point-to-point sends/recvs. * Remove trailing whitespace

* Refactor of MPI-IO support in fms2_io MPI-IO support in fms2_io has been refactored. `open_collective_netcdf_file` has been removed and its functionality has been merged into `netcdf_file_open`. Parallel reads and writes are now enabled using the same interface and code pathways. * Specify argument names in `netcdf_file_open` call Use explicit names for the optional arguments of `netcdf_file_open`, when it's called within `open_domain_file`. * netcdf_read_data_*: Call nf90_var_par_access later In the netcdf_read_data_* subroutines, move the calls to nf90_var_par_access so that they run later. * Fix domain reads when MPI-IO is enabled Update the domain read subroutines so that they set the indices correctly when use_netcdf_mpi is enabled. * Remove fallback test for collective reads Remove the test which attempts to open a 64-bit NetCDF file in collective read mode. Attempting to do so will now fail rather than fall back to a standard read without MPI-IO. * Restore working version of netcdf_read_data.inc Undo changes to netcdf_read_data.inc which were committed unintentionally. * Update call to open_file in diag_manager * Restore collective read unit test Restore the unit test which attempts to open a 64-bit NetCDF file for MPI-IO collective reads. Change from `test_expect_success` to `test_expect_failure`. * Explain MPI-IO features in README Add an explanation of fms2_io's MPI-IO support to the readme.md file. --------- Co-authored-by: Jesse Lentz <jesse@twosheds.org> Co-authored-by: Jesse Lentz <jesse.lentz@noaa.gov>
