C------ |

C GlobalFiles option with Multi-processors execution (with MPI) is not |
| 67 |
C safe: dependending on the platform & compiler, it may produce: |
| 68 |
C - incomplete output files (wrong size) |
| 69 |
C - wrong isolated values in some output files |
| 70 |
C - missing tiles (all zeros) in some output files. |
| 71 |
C A safe alternative is to set "useSingleCpuIO=.TRUE." in file "data", |
| 72 |
C namelist PARAM01 (and to keep the default value of globalFiles=FALSE) |
| 73 |
C or if you are really sure that the globalFile works well on our platform |
| 74 |
C & compiler, comment out the above "stop" |
