c o Run the ocean model and evaluate the specified cost function. |
24 |
c |
25 |
c *the_main_loop* is the top-level routine for the Tangent Linear and |
26 |
c Adjoint Model Compiler (TAMC). For this purpose, the initialization |
27 |
c of the model was split into two parts. Those parameters that do |
28 |
c not depend on a specific model run are set in *initialise_fixed*, |
29 |
c whereas those that do depend on the specific realization are |
30 |
c initialized in *initialise_varia*. In order to do a so called |
31 |
c checkpointing during the adjoint calculation and to account for the |
32 |
c typical data involved in oceanographic applications a call tree |
33 |
c that is divided into yearly, monthly, daily, and step parts can |
34 |
c be used. |
35 |
c |
36 |
c This routine is to be used in conjuction with the MITgcmuv release |
37 |
c checkpoint 24. |

42 |
c |
43 |
c - The call to mapping was moved to initialise_varia, |
44 |

c Christian Eckert eckert@mit.edu 11-Feb-2000 |

50 |
c for the MITgcmUV. |

c |
52 |
c Patrick Heimbach heimbach@mit.edu 3-Jun-2000 |
