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 because i
write message just before (it is the END_OF macro in my program), and i
am sure all processes are locked in MPI_Finalize() function beacause i
write message just after (it is the MESSAGE macro).
May be all MPI_Sends are not matched by corresponding MPI_Recvs,... It
can be a possibility.
Thanks

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.

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.

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!
