 ||compiler_name     ||Name of the FORTRAN compiler to be used to create the PALM executable. Typically, this is the name of a wrapper script like ''mpif90'' or e.g. ''ftn'' on Cray machines, which automatically invokes the required MPI library and MPI include file. If you don't have a wrapper script, you may need to explicitly give compiler options (see {{{compiler_options}}}) to provide paths to the library / include file. If you like to run PALM without MPI (serial mode, or OpenMP parallelization), you should not use a wrapper script and give the original compiler name instead. ||no default value  ||
 ||compiler_name_ser ||FORTRAN compiler name to create non-MPI executables. This name is required, because {{{palmbuild}}} generates several helper programs for pre-/post-processing, which run in serial mode on just one code. Here you give the original compiler name, like ''ifort'', ''pgfortran'', ''gfortran'', or ''xlf95''.  ||no default value  ||  
+||cpp_options       ||Preprocessor directives to be used for compiling the PALM code. They allow for conditional compilation using the {{{-D}}} compiler option. Compiling PALM with MPI support requires options {{{-D__parallel -DMPI_REAL=MPI_DOUBLE_PRECISION -DMPI_2REAL=MPI_2DOUBLE_PRECISION}}}. Many compilers require to set an additional option to run the FORTRAN preprocessor on source files before compilation (e.g. ''-fpp'' for the Intel compiler). This option has to be given here too. Alternatively, you can provide it as part of the {{{compiler_options}}}. See [wiki:doc/app/cpp_options cpp_options] for a complete list of preprocessor define strings that are used in the PALM code.  ||no default value  ||
