C *========================================================== C | The following CPP flag (MULTIPLE_RECORD_GGL90_STATE_FILES) is C | #define/#undefed here since it is specific to this routine C | and very user-preference specific. C | C | If #undefed (default) the state files are written as in all versions C | prior to checkpoint32, where a file is created per variable, per time C | and per tile. This *has* to be the default because most users use this C | mode and all utilities and scripts (diagnostic) assume this form. C | It is also robust, as explained below. C | C | If #defined, subsequent snap-shots are written as records in the C | same file (no iteration number in filenames). C | Advantages: - fewer files C | - for small problems, is easy to copy the output around C | Disadvantages: C | - breaks a lot of diagnostic scripts C | - for large or long problems this creates huge files C | - is an unexpected, unsolicited change in behaviour which came C | as a surprise (in c32) and inconvenience to several users C | - can not accomodate changing the frequency of output C | after a pickup (this is trivial in previous method C | but needs new code and parameters in this new method) C *==========================================================* C \ev C !USES: IMPLICIT NONE C === Global variables === #include "SIZE.h" #include "EEPARAMS.h" #include "PARAMS.h" #include "GGL90.h" #include "GGL90_TAVE.h" C !INPUT/OUTPUT PARAMETERS: C == Routine arguments == C myTime :: my time in simulation ( s ) C myIter :: my Iteration number C myThid :: my Thread Id number _RL myTime INTEGER myIter INTEGER myThid #ifdef ALLOW_GGL90 C !FUNCTIONS: LOGICAL DIFFERENT_MULTIPLE EXTERNAL DIFFERENT_MULTIPLE C !LOCAL VARIABLES: C == Local variables == CHARACTER*(MAX_LEN_MBUF) suff #ifdef ALLOW_TIMEAVE INTEGER bi, bj _RL DDTT #endif CEOP C---------------------------------------------------------------- C Dump snapshot of GGL90 variables.
