|
C *==========================================================* |
| 13 |
|
|
C | SUBROUTINE PP81_OUTPUT |
| 14 |
|
|
C | o Do PP81 diagnostic output. |
| 15 |
|
|
C *========================================================== |
| 16 |
|
|
C | The following CPP flag (MULTIPLE_RECORD_PP81_STATE_FILES) is |
| 17 |
|
|
C | #define/#undefed here since it is specific to this routine |
| 18 |
|
|
C | and very user-preference specific. |
| 19 |
|
|
C | |
| 20 |
|
|
C | If #undefed (default) the state files are written as in all versions |
| 21 |
|
|
C | prior to checkpoint32, where a file is created per variable, per time |
| 22 |
|
|
C | and per tile. This *has* to be the default because most users use this |
| 23 |
|
|
C | mode and all utilities and scripts (diagnostic) assume this form. |
| 24 |
|
|
C | It is also robust, as explained below. |
| 25 |
|
|
C | |
| 26 |
|
|
C | If #defined, subsequent snap-shots are written as records in the |
| 27 |
|
|
C | same file (no iteration number in filenames). |
| 28 |
|
|
C | Advantages: - fewer files |
| 29 |
|
|
C | - for small problems, is easy to copy the output around |
| 30 |
|
|
C | Disadvantages: |
| 31 |
|
|
C | - breaks a lot of diagnostic scripts |
| 32 |
|
|
C | - for large or long problems this creates huge files |
| 33 |
|
|
C | - is an unexpected, unsolicited change in behaviour which came |
| 34 |
|
|
C | as a surprise (in c32) and inconvenience to several users |
| 35 |
|
|
C | - can not accomodate changing the frequency of output |
| 36 |
|
|
C | after a pickup (this is trivial in previous method |
| 37 |
|
|
C | but needs new code and parameters in this new method) |
