C *==========================================================* |

C | SUBROUTINE EESET_PARMS |
| 16 |
C | o Routine to set model "parameters" |
| 17 |
C *==========================================================* |
| 18 |
C | This routine is called from the high-level wrapper |
| 19 |
C | after multi-process paralle processing has started but |
| 20 |
C | before multi-threaded parallelism. THe routine reads an |
| 21 |
C | an "execution environment" input parameter file holding |
| 22 |
C | information about the number of threads at run-time. |

C usingMPI is a flag which controls whether MPI message |

C If usingMPI is set to TRUE but % mpirun .... was not |

C may be generated when the first MPI call ( CALL MPI_Init ) |
