|
C | o Controlling routine for IO in model main time-stepping | |

C | loop. | |
| 10 |
|
|
C |==========================================================| |
| 11 |
|
|
C | Many systems do not have thread safe IO so it is easier | |
| 12 |
|
|
C | to lump everything together and do dumping of fields | |
| 13 |
|
|
C | and updating of forcing terms in a single place. | |
| 14 |
|
|
C | The approach to IO used here is that writes are only | |
| 15 |
|
|
C | performed by thread 1 and that a process only writes out | |
| 16 |
|
|
C | its data ( since it doen't know about anyone elses data!)| |
| 17 |
|
|
C | Reading on the other hand is assumed to be from a file | |
| 18 |
|
|
C | containing all the data for all the processes. Only the | |
| 19 |
|
|
C | portion of data of interest to this process is actually | |
| 20 |
|
|
C | loaded. To work well this assumes the existence of some | |
| 21 |
|
|
C | reliable tool to join datasets together at the end of a | |
| 22 |
|
|
C | run. | |

|
C | ===== | |
| 25 |
|
|
C | We allow thread 2-nThreads to continue whilst thread 1 | |
| 26 |
|
|
C | does IO. The assumption is that the other threads won't | |
| 27 |
|
|
C | do anything to update their interior regions before | |
| 28 |
|
|
C | thread 1 has finished writing them out. | |
