Machine issues & portability
On this page we list the compiler-dependent and platform-dependent issues that we have recently encountered.
Contents
GNU Fortran compiler
The GNU Fortran compiler (aka gfortran) is our recommended compiler for 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].
Please see our GNU Fortran compiler wiki page for more information about the compilation options used by GEOS-Chem.

IFORT 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.
