Hi, all!
I am trying to do MPI_REDUCE(3f) on the IMPI. But MPI_REDUCE(3f) can not execute well.
Can not this function work well on IMPI?
I've tried on LAM 6.5.6 too, But even simple IMPI program can not execute.
$ cat a.f
PROGRAM MAIN
include 'mpif.h'
INTEGER NPROCS,MYRANK,IERROR
INTEGER ITMP,IRSLT
CALL MPI_INIT(IERROR)
CALL MPI_COMM_RANK(MPI_COMM_WORLD,MYRANK,IERROR)
PRINT *,'MYRANK= ',MYRANK
ITMP=MYRANK
CALL MPI_REDUCE(ITMP,IRSLT,1,MPI_INTEGER,MPI_MAX,0,
& MPI_COMM_WORLD,IERROR)
PRINT *,'IRSLT= ',IRSLT
CALL MPI_FINALIZE(IERROR)
STOP
END

-----------------------------------------------------------------------------
One of the processes started by mpirun has exited with a nonzero exit
code. This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.
PID 20546 failed on node n0 with exit status 1.
