C | SUBROUTINE THE_MODEL_MAIN | |
| 5 |
C | o Master controlling routine for model using the MITgcm | |
| 6 |
C | UV parallel wrapper. | |
| 7 |
C |==========================================================| |
| 8 |
C | THE_MODEL_MAIN is invoked by the MITgcm UV parallel | |
| 9 |
C | wrapper with a single integer argument "myThid". This | |
| 10 |
C | variable identifies the thread number of an instance of | |
| 11 |
C | THE_MODEL_MAIN. Each instance of THE_MODEL_MAIN works | |
| 12 |
C | on a particular region of the models domain and | |
| 13 |
C | synchronises with other instances as necessary. The | |
| 14 |
C | routine has to "understand" the MITgcm parallel | |
| 15 |
C | environment and the numerical algorithm. Editing this | |
| 16 |
C | routine is best done with some knowledge of both aspects.| |
