C !INTERFACE: |

SUBROUTINE WRITE_STATE ( myTime, myIter, myThid ) |
| 15 |
|
| 16 |
C !DESCRIPTION: |
| 17 |
C This is the controlling routine for writing mid-level IO. It |
| 18 |
C includes code for diagnosing W and RHO for output. |
| 19 |
|
| 20 |
C The CPP flag (MULTIPLE_RECORD_STATE_FILES) is #define/#undefed |
| 21 |
C here since it is specific to this routine and very user-preference |
| 22 |
C specific. If #undefed (default) the state files are written as in |
| 23 |
C all versions prior to checkpoint32, where a file is created per |
| 24 |
C variable, per time and per tile. This *has* to be the default |
| 25 |
C because most users use this mode and all utilities and scripts |
| 26 |
C (diagnostic) assume this form. It is also robust, as explained |
| 27 |
C below. |
| 28 |
C |
| 29 |
C If #defined, subsequent snap-shots are written as records in the |
| 30 |
C same file (no iteration number in filenames). The main advantage |
| 31 |
C is fewer files. The disadvantages are that: |
| 32 |
C (1) it breaks a lot of diagnostic scripts, |
| 33 |
C (2) for large or long problems this creates huge files, |
| 34 |
C (3) its an unexpected, unsolicited change in behaviour which |
| 35 |
C came as a surprise (in c32) and is an inconvenience to |
| 36 |
C several users |
| 37 |
C (4) it can not accomodate changing the frequency of output |
| 38 |
C after a pickup (this is trivial in previous method but |
| 39 |
C needs new code and parameters in this new method) |
| 40 |
C |
| 41 |
C Known Bugs include: |
| 42 |
C (1) if the length of integration is not exactly an integer |
| 43 |
C times the output frequency then the last record written |
| 44 |
C (at end of integration) overwrites a previously written |
| 45 |
C record corresponding to an earier time. *BE WARNED* |
