In this section we present information about the various optimization options available in the Intel Fortran Compiler. Please see our Guide to GEOS-Chem performance for a summary of recent timing tests done with the Intel Fortran compiler. If you do not request the maximum amount of stack memory, then your GEOS-Chem simulation will not have enough memory to create temporary variables (including those created within OpenMP parallel loops).įor detailed instructions, please see Getting Started with GEOS-Chem: Specifying settings for OpenMP parallelization. In order to run GEOS-Chem with Intel Fortran, you must request the maximum amount of stack memory in your Unix environment. Requesting sufficient stack memory for GEOS-Chem Please see our Getting Started with GEOS-Chem: Configuring your computational environment for detailed instructions. If these variables are not automatically set by the module command on your system (or if your system does not use a module manager, then you will need to set these manually. $NETCDF_FORTRAN_HOME/lib or $NETCDF_FORTRAN_HOME/lib64) Path to the netCDF Fortran library folder (e.g.

Path to the netCDF Fortran include folder (e.g. Your module manager *may* automatically define several environment variables for you: You can ask your IT staff what the corresponding commands would be on your particular cluster. # These commands load Intel Fortran 17 on the Harvard "Cannon" cluster For example, we use the following commands on the Harvard cluster (cannon.rc.): On many computer systems, a module manager such as Lmod or environment-modules can be used to load the Intel Fortran compiler library (and its dependencies) into your Unix environment. 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.
