1.42 |
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 *==========================================================* |

|
|
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. |
