On this page we list the compiler-dependent and platform-dependent issues that we have recently encountered.

GNU Fortran compiler

We recommend that you use the GNU Fortran compiler (aka gfortran) with GEOS-Chem. Because gfortran is open-source, it can be used on a wide variety of platforms, including the [Amazon Web Services cloud computing platform]. GEOS-Chem is now compatible with gfortran 4.4.7 and higher. (As of December 2018, the current version is gfortran 8.2.0).

Please see our GNU Fortran compiler wiki page for more information about the compilation options used by GEOS-Chem, as well as a list of known issues.

Intel Fortran Compiler

The Intel Fortran Compiler (aka ifort) can currently be used to compile GEOS-Chem. However, this compiler is proprietary and requires that you (or your IT department) to purchase a site license, which can be expensive.

Please see our Intel Fortran Compiler wiki page for more information about the options used to compile GEOS-Chem, as well as a list of known issues.

PGI Compiler

NOTE: While GEOS-Chem can probably compile and run with the PGI compiler, we are no longer actively supporting it. We recommend that you use the open-source GNU Fortran Compiler instead.

Please see the Portland Group Int'l vendor website for PGI compiler documentation.

Compatibility issues added in v9-01-02

Please see this list of minor bugs that were corrected in order to get the GEOS-Chem code to compile with the PGI compiler.
