    3838 * '''Note on parallelization:''' PDAF is generally intended for parallel computing using MPI. However, it can be compiled for serial computing. To compile PDAF for this case a simplified MPI header file is included in `src/dummympi` and should be in the include path. In addition, a dummy implementation of MPI, which behaves like MPI in the single-process case, is provided in the directory `nullmpi/`. For the serial case, this file should also be compiled and linked when PDAF is linked to a program. The include files in `make.arch` without MPI-parallelization include the required settings.

     40 * '''Note on precision of floating point variables:''' PDAF is designed to use floating point variables of double precision. However, for flexibility the variables are decared in the source code without a 'KIND' specification. Thus, for the compilation one has to specify that the compiler treats all 'real' variables with double precision accuracy. This is done, e.g. for gfortran by setting `-fdefault-real-8` or for ifort by setting `-r8`. In the provided include files in `make.arch/` these specifications are included.
