10 SUBROUTINE WRITE_STATE ( myCurrentTime, myIter, myThid )
11 C !DESCRIPTION: \bv
12 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*
