c o Run the ocean model and evaluate the specified cost function. |
| 20 |
c |
| 21 |
c *the_main_loop* is the top-level routine for the Tangent Linear and |
| 22 |
c Adjoint Model Compiler (TAMC). For this purpose, the initialization |
| 23 |
c of the model was split into two parts. Those parameters that do |
| 24 |
c not depend on a specific model run are set in *initialise_fixed*, |
| 25 |
c whereas those that do depend on the specific realization are |
| 26 |
c initialized in *initialise_varia*. In order to do a so called |
| 27 |
c checkpointing during the adjoint calculation and to account for the |
| 28 |
c typical data involved in oceanographic applications a call tree |
| 29 |
c that is divided into yearly, monthly, daily, and step parts can |
| 30 |
c be used. |
| 31 |
c |
| 32 |
c This routine is to be used in conjuction with the MITgcmuv release |
| 33 |
c checkpoint 24. |

c changed: Christian Eckert eckert@mit.edu 14-Jul-1999 |
| 38 |
c |
| 39 |
c - The call to mapping was moved to initialise_varia, |
| 40 |
c since this routine has to be called before |

c ini_predictor. |

c |

c Patrick Heimbach heimbach@mit.edu 3-Jun-2000 |
