Update Intel Fortran Flag #241

Closed mathomp4 closed 2 years ago

mathomp4 commented 2 years ago

This changes the default vectorization flag for Intel Fortran from -xCORE-AVX2 to -march=core-avx2. This change allows GEOS to run on both Intel and AMD EPYC chips at NAS without need for another build, see https://github.com/GEOS-ESM/ESMA_cmake/issues/240 for more details.

Closes #240
