Subject: Re: [OMPI users] dead lock in MPI_Finalize

Hi Bernard

The structure looks as far as i can see.
Did it run OK on Open-MPI 1.2.X?
So are you sure all processes reach the MPI_Finalize command?
Usually MPI_Finalize only completes when all processes reach it.
I think you should also make sure that all MPI_Sends are matched by
corresponding MPI_Recvs.
