C *==========================================================* |
| 13 |
C | SUBROUTINE WRITE_STATE |
| 14 |
C | o Controlling routine for IO to dump model state. |
| 15 |
C *==========================================================* |
| 16 |
C | Write model state files for post-processing. This file |
| 17 |
C | includes code for diagnosing W and RHO for output. |
| 18 |
C | File write_state.F: Routines to handle mid-level I/O |
| 19 |
C | interface. |
| 20 |
C | o WRITE_STATE - Write out model state. |
| 21 |
C | The following CPP flag (MULTIPLE_RECORD_STATE_FILES) is |
| 22 |
C | #define/#undefed here since it is specific to this routine |
| 23 |
C | and very user-preference specific. |
| 24 |
C | |
| 25 |
C | If #undefed (default) the state files are written as in all versions |
| 26 |
C | prior to checkpoint32, where a file is created per variable, per time |
| 27 |
C | and per tile. This *has* to be the default because most users use this |
| 28 |
C | mode and all utilities and scripts (diagnostic) assume this form. |
| 29 |
C | It is also robust, as explained below. |
| 30 |
C | |
| 31 |
C | If #defined, subsequent snap-shots are written as records in the |
| 32 |
C | same file (no iteration number in filenames). |
| 33 |
C | Advantages: - fewer files |
| 34 |
C | - for small problems, is easy to copy the output around |
| 35 |
C | Disadvantages: |
| 36 |
C | - breaks a lot of diagnostic scripts |
| 37 |
C | - for large or long problems this creates huge files |
| 38 |
C | - is an unexpected, unsolicited change in behaviour which came |
| 39 |
C | as a surprise (in c32) and inconvenience to several users |
| 40 |
C | - can not accomodate changing the frequency of output |
| 41 |
C | after a pickup (this is trivial in previous method |
| 42 |
C | but needs new code and parameters in this new method) |
| 43 |
C | Known Bugs: |
| 44 |
C | - if the length of integration is not exactly an integer |
| 45 |
C | times the output frequency then the last record written |
| 46 |
C | (at end of integration) overwrites a previously written |
| 47 |
C | record corresponding to an earier time. *BE WARNED* |
