C *==========================================================* |
| 14 |
C | SUBROUTINE INI_PROCS |
| 15 |
C | o Initialise multiple concurrent processes environment. |
| 16 |
C *==========================================================* |
| 17 |
C | Under MPI this routine calls various MPI service routines |
| 18 |
C | that map the model grid to MPI processes. The information |
| 19 |
C | is then stored in a common block for later use. |
| 20 |
C | Note: This routine can also be compiled with CPP |
| 21 |
C | directives set so that no multi-processing is initialise. |
| 22 |
C | This is OK and should work fine. |
