[MITgcm-support] Problem with MPI execution

[Martin Losch]

I don't think that the MPI within the MITgcm is the problem. Try to  
generate a non-mpi executable and see if the problem goes away.

The error message is clear: eedata cannot be opened. Is it in the  
correct directory? What about read permissions? Maybe the read  
permission are different for mpirun? This is the code where it happens:

>       OPEN(UNIT=eeDataUnit,FILE='eedata',STATUS='OLD',
>      &     err=1,IOSTAT=errIO)
>       IF ( errIO .GE. 0 ) GOTO 2
>     1 CONTINUE
>        WRITE(msgBuf,'(A)')
>      &  'S/R EESET_PARMS'
>        CALL PRINT_ERROR( msgBuf , 1)
>        WRITE(msgBuf,'(A)')
>      &  'Unable to open execution environment'
>        CALL PRINT_ERROR( msgBuf , 1)
>        WRITE(msgBuf,'(A)')
>      &  'parameter file "eedata"'
>        CALL PRINT_ERROR( msgBuf , 1)
>        CALL EEDATA_EXAMPLE
>        STOP 'ABNORMAL END: S/R EESET_PARMS'

no other ideas on this side of the Atlantic ...
