0003 # Build options for gfortran compiler (GNU) on Linux AMD64 platform
0004 #
0005 # Should work with both AMD and Intel processors that support AVX2 instructions.
0006 #
0007 # Tested with gfortran 12.2.0
0008 #
0009 # MPI : Tested on engaging on Rocky Linux 8.10 with
0010 # module load gcc/12.2.0
0011 # module load openmpi/4.1.4
0012 # module load netcdf-c/4.9.2
0013 # module load netcdf-fortran/4.6.1
