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 | |
