Additional or summary comments: | Results from our v11-02a benchmark using the GNU Fortran Compiler
We also performed an identical v11-02a benchmark, having compiled GEOS-Chem with gfortran 6.2.0. We obtained essentially identical results to the benchmark reported in this table, which used ifort 11.1.069 to compile GEOS-Chem.
