C *==========================================================* |
| 13 |
C | SUBROUTINE WRITE_PICKUP |
| 14 |
C | o Controlling routine for IO to write restart file. |
| 15 |
C *==========================================================* |
| 16 |
C | Write model checkpoint files for use in restart. |
| 17 |
C | This routine writes both "rolling-checkpoint" files |
| 18 |
C | and permanent checkpoint files. A rolling checkpoint |
| 19 |
C | works through a circular list of suffices. Generally the |
| 20 |
C | circular list has two entries so that a rolling |
| 21 |
C | checkpoint will overwrite the last rolling checkpoint |
| 22 |
C | but one. This is useful for running long jobs without |
| 23 |
C | filling too much disk space. |
| 24 |
C | In a permanent checkpoint data is written suffixed by |
| 25 |
C | the current timestep number. This sort of checkpoint can |
| 26 |
C | be used to provided a snap-shot from which the model |
| 27 |
C | can be rerun. |
