On this page we provide information about the compilers that are supported in GEOS-Chem.

The GNU Fortran compiler

GNU Fortran is our recommended open-source compiler for GEOS-Chem.

GEOS-Chem v11-01 and newer versions are compatible with the GNU Fortran compiler, aka gfortran. This is a free and open-source compiler that comes pre-installed on many modern computer systems. As such, GNU Fortran allows GEOS-Chem to be highly portable across a wide variety of platforms, including cloud-computing platforms.

The Intel Fortran compiler

Intel Fortran is our recommended proprietary compiler for GEOS-Chem.

Many users compile GEOS-Chem with the Intel Fortran compiler (aka ifort). In general, you will always obtain the best performance when compiling GEOS-Chem using Intel Fortran AND running GEOS-Chem on a system with Intel CPUs.
