MAPL 2.51.1

This is a patch on MAPL 2.51. This release fixes an issue where the per-cell counters in the generic coupler are not initialized properly. They are part of a derived type when gets allocated, but the pointers there are not initialized to NULL.

Testing of GEOS at c24 and c360 shows this to be zero-diff. However, there is the possibility that if you encountered this bug, some output could change.

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.
