how do you know all process call mpi_finalize? did you have all of them
print out something before they call mpi_finalize? I think what Gustavo is
getting at is maybe you had some MPI calls within your snippets that hangs
your program, thus some of your processes never called mpi_finalize.

Thanks,
But, my code is too long to be posted.
What are the common reasons of this kind of problems ?
Any help is appreciated.

Hi Jack
Your code snippet is too terse, doesn't show the MPI calls.
It is hard to guess what is the problem this way.

Thanks for the reply. But, I use mpi_waitall() to make sure that all MPI
communications have been done before a process call MPI_Finalize() and returns.
Any help is appreciated.

Hi Jack
It may depend on "do some things".
Does it involve MPI communication?
Also, why not put MPI_Finalize();return 0 outside the ifs?

Hi
I got a problem of open MPI.
My program has 5 processes.
All of them can run MPI_Finalize() and return 0.
But, the whole program cannot be completed.
In the MPI cluster job queue, it is strill in running status.
If I use 1 process to run it, no problem.
Why ?
My program:
int main (int arg
