C | Under MPI this routine calls various MPI service routines| |

C | that map the model grid to MPI processes. The information| |
| 10 |
C | is then stored in a common block for later use. | |

C | Note: This routine can also be compiled with CPP | |

C | directives set so that no multi-processing is initialise.| |
