C *==========================================================* |
| 11 |
C | SUBROUTINE OBCS_EXTERNAL_FIELDS_LOAD |
| 12 |
C | o Control reading of fields from external source. |
| 13 |
C *==========================================================* |
| 14 |
C | External source field loading routine for open boundaries. |
| 15 |
C | This routine is called every time we want to |
| 16 |
C | load a a set of external open boundary fields. |
| 17 |
C | Only if there are fields available (file names are not empty) |
| 18 |
C | the open boundary fields are overwritten. |
| 19 |
C | The routine decides which fields to load and then reads them in. |
| 20 |
C | This routine needs to be customised for particular |
| 21 |
C | experiments. |
| 22 |
C | Notes |
| 23 |
C | ===== |
| 24 |
C | Two-dimensional and three-dimensional I/O are handled in |
| 25 |
C | the following way under MITgcmUV. A master thread |
| 26 |
C | performs I/O using system calls. This threads reads data |
| 27 |
C | into a temporary buffer. At present the buffer is loaded |
| 28 |
C | with the entire model domain. This is probably OK for now |
| 29 |
C | Each thread then copies data from the buffer to the |
| 30 |
C | region of the proper array it is responsible for. |
| 31 |
C | ===== |
| 32 |
C | This routine is the complete analogue to external_fields_load, |
| 33 |
C | except for exchanges of forcing fields. These are done in |
| 34 |
C | obcs_precribe_exchanges, which is called from dynamics. |
| 35 |
C | - Forcing period and cycle are the same as for other fields |
| 36 |
C | in external forcing. |
| 37 |
C | - constant boundary values are also read here and not |
| 38 |
C | directly in obcs_init_variables (which calls obcs_calc |
| 39 |
C | which in turn calls this routine) |
