    5151For the offline mode, the variable `n_modeltasks` should always be set to one, because no integrations are performed in the assimilation program. The routine `init_parallel_pdaf` splits the communicator `MPI_COMM_WORLD` and defines the three communicators described above. In addition, the variables `npes_world` and `mype_world` are defined. These can be used in the user-supplied routines to control, for example, which process write information to the screen. The routine defines several more variables that are declared and held in the module `mod_parallel`. It can be useful to use this module with the model code as some of these variables are required when the initialization routine of PDAF (`PDAF_init`) is called.

    53 The initialization of the communicators is different for the offline and online modes. You can find a template in the tutorial implementations for the offline case, e.g. in `tutorial/offline_2D_parallel`.
