C *==========================================================* |
| 14 |
C | SUBROUTINE ALL_PROC_DIE |
| 15 |
C | o when all process call this routine, die cleanly: |
| 16 |
C | set Error-Flag and call MPI finalise |
| 17 |
C *==========================================================* |
| 18 |
C | used before a STOP: |
| 19 |
C | - Only implemented for MPI multi-proc. |
| 20 |
C | - if some Proc do not call this S/R, MPI will hang. |
