Hi,
When I run my MPI application over 40 machines, one mpi process does not finish and hangs on 'MPI_Finalize'
(The other mpi processes in the other machines show zero cpu usage)
In the bellow, I attached the call stack of the process which is waiting on 'MPI_Finalize' function.
where do I have to start debugging? can anybody give me any clue on it?
