Hi Jody,
I think it is not a problem of MPI_Sends which doesn't match a
corresponding MPI_Recvs, because all processes reach MPI_Finalize(). If
not, at least one process would be blocked before reaching MPI_Finalize.

Thanks for your messages. Yes i disconnect my different worlds before

I was somehow confused when I wrote my last email and I mixed up the

I don't know what your program is doing but I kind of guess what the

Without knowing the internal details of the program,
it's difficult to tell what could be going wrong.

Perhaps you should try to incrementalls reduce the
functionality of your program while keeping the error.
That way you may reach a state where it may be ea
No i didn't run this program whith Open-MPI 1.2.X because one said to me
there were many changes between 1.2.X version and 1.3 version about
MPI_publish_name, MPI_Lookup_name (new ompi-server, ...), and it was
better to use 1.3 version.
Yes i am sure all processes reach MPI_Finalize() function
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_
Thanks Jody for your answer.
I launch 2 instances of my program on 2 processes each instance, on the
same machine.
I use MPI_Publish_name, MPI_Lookup_name to create a global communicator
on the 4 processes.
Then the 4 processes exchange data.
The main program is a CORBA server. I send you th

- how many processes on how many machines,
- what kind of computation
- perhaps minimal code which reproduces this failing

Hello Jeff,
I don't understand what you mean by "A _detailed_ description of what is
failing".
The problem is a dead lock in MPI_Finalize() function. All processes are
blocked in this MPI_Finalize() function.
