     109The module `mod_parallel.F90` from the template directory provides subroutines for the initialization and finalization of MPI. Thus, if this module is used, one can simply add
     110{{{
     111    CALL init_parallel()
     112}}}
     113at the beginning of the program and
     114{{{
     115    CALL finalize_parallel()
     116}}}
     117to the source code.
