|
C | SUBROUTINE INITIALISE |
| 16 |
|
|
C | o Routine to initialise coupling component. |
| 17 |
|
|
C *==========================================================* |
| 18 |
|
|
C | Initialisation involves starting up MPI and then joining |
| 19 |
|
|
C | the coupled configuration as a component with the special |
| 20 |
|
|
C | name "Coupler". With the present MIT Coupler library |
| 21 |
|
|
C | only one process can register with the name "Coupler". |
| 22 |
|
|
C | This component is the process responsible for |
| 23 |
|
|
C | coordinating the transfer of data between other |
| 24 |
|
|
C | components and for mapping data from one components |
| 25 |
|
|
C | representation to anothers representation as appropriate. |
