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 passing library calls are actually made. Note that under |
| 78 |
C MPI it is necessary to start a program a special way - |
| 79 |
C normally using a command of the form |
| 80 |
C % mpirun program_name |
| 81 |
C If usingMPI is set to TRUE but % mpirun .... was not |
| 82 |
C used to launch the program then an internal MPI error |
| 83 |
C may be generated when the first MPI call ( CALL MPI_Init ) |
| 84 |
C is made. |

C |
| 86 |
C useCoupler is a flag which controls communications with other |
| 87 |
C model components through a coupler interface. |

C |

C useSETRLSTK is a flag which toggles calling a small C routine |
| 90 |
C which sets the stack size to "unlimited" using setrlimit() |
