C------ |

|
|
C GlobalFiles option with Multi-processors execution (with MPI) is not |
| 43 |
|
|
C safe: dependending on the platform & compiler, it may produce: |
| 44 |
|
|
C - incomplete output files (wrong size) |
| 45 |
|
|
C - wrong isolated values in some output files |
| 46 |
|
|
C - missing tiles (all zeros) in some output files. |
| 47 |
|
|
C A safe alternative is to set "useSingleCpuIO=.TRUE." in file "data", |
| 48 |
|
|
C namelist PARAM01 (and to keep the default value of globalFiles=FALSE) |
| 49 |
|
|
C or if you are really sure that the globalFile works well on our platform |
| 50 |
|
|
C & compiler, comment out the above "stop" |
