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 this program.

For instance:
- how many processes on how many machines,
- what kind of computation
- perhaps minimal code which reproduces this failing
- configuration settings, etc.
See: http://www.open-mpi.org/community/help/
Without any information except for "it doesn't work",
nobody can give you any help whatsoever.

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.

Jeff Squyres a écrit :
Per this note on the "getting help" page, we still need the following:
"A _detailed_ description of what is failing. The more details that you
provide, the better. E-mails saying "My application doesn't work!" will
inevitably be answered with requests for more information about exactly what
doesn't work; so please include as much information detailed in your initial
e-mail as possible."
Additionally:
"The best way to get help is to provide a "recipie" for reproducing the
problem."
Thanks!
