C !INTRODUCTION: Kernel dynamical routines |
| 11 |
C This document summarises MITgcm code under the model/ subdirectory. |
| 12 |
C The code under model/ ( src/ and inc/ ) contains most of |
| 13 |
C the driver routines for the baseline forms of the kernel equations in the |
| 14 |
C MITgcm algorithm. Numerical code for much of the baseline forms of |
| 15 |
C these equations is also under the model/ directory. Other numerical code |
| 16 |
C used for the kernel equations is contained in packages in the pkg/ |
| 17 |
C directory tree. |
| 18 |
C Code for auxilliary equations and alternate dicretizations of the kernel |
| 19 |
C equations and algorithm can also be found in the pkg/ directory tree. |

C *==========================================================* |
| 413 |
C | SUBROUTINE THE_MODEL_MAIN |
| 414 |
C | o Master controlling routine for model using the MITgcm |
| 415 |
C | UV parallel wrapper. |
| 416 |
C *==========================================================* |
| 417 |
C | THE_MODEL_MAIN is invoked by the MITgcm UV parallel |
| 418 |
C | wrapper with a single integer argument "myThid". This |
| 419 |
C | variable identifies the thread number of an instance of |
| 420 |
C | THE_MODEL_MAIN. Each instance of THE_MODEL_MAIN works |
| 421 |
C | on a particular region of the models domain and |
| 422 |
C | synchronises with other instances as necessary. The |
| 423 |
C | routine has to "understand" the MITgcm parallel |
| 424 |
C | environment and the numerical algorithm. Editing this |
| 425 |
C | routine is best done with some knowledge of both aspects. |
