Using a module manager to load GNU Fortran and related libraries Here is some information about how you can customize your Unix environment to use the Intel Fortran compiler. In v11-01 we will test if this is resolved by the recent code updates. NOTE: compiler bug in ifort 12 and higher versions has forced us to add a workaround to HEMCO.NOTE: IFORT 15 has a compiler bug that causes errors when turning on array-out-of-bounds checking and optimization.Please see our Known issues caused by compiler bugs wiki page more information.

NOTE: Certain Intel Fortran compiler versions are known to cause issues. But you should be able to use other Intel Fortran Compiler versions as well. The GEOS-Chem Support Team has tested GEOS-Chem with the compiler versions listed below. Intel Fortran Compiler versions that have been tested with GEOS-Chem You can find more information about the Intel Fortran Compiler here:Īlso, normally when you installs the Intel Fortran compilers, you also will install the C and C++ compilers. If your institution does not have the resources to purchase the Intel Fortran Compiler, then we recommend that you use the GNU Fortran compiler-which is free and open source-instead. Intel Fortran requires the purchase of an expensive site license. 5.14 Bugs in the IFORT compiler cause HEMCO to segfault.5.13 Performance bottleneck caused by inefficient subroutine calls.5.12 Speedup With Hyperthreading on Nehalem chips.5.11 Incompatibility between IFORT 11 and OS version.5.10 Problem with IFORT 11 and GEOS-Chem adjoint.5.6 Error compiling with IFORT 12 and Mac OS X.5.5 Bug fix for GEOS-Chem compiled with Intel Fortran Compiler 12.5.2 Cannot compile GEOS-Chem v10-01 with Intel Fortran Compiler v17.5.1 Compilation issues with Intel Fortran 18.4.6 Caveat about optimizing for specific chipsets.4.4 Optimization options for faster runs.4.2.2 Typical settings for a GEOS-Chem simulation.4.2.1 List of commonly-used compilation options.4.2 Recommended compilation and optimization options for GEOS-Chem.2.2 Requesting sufficient stack memory for GEOS-Chem.2.1 Using a module manager to load GNU Fortran and related libraries.2 Environment settings for Intel Fortran.1.3 Intel Fortran Compiler versions that have been tested with GEOS-Chem.
