[OMPI users] mpirun hangs with multiple nodes

Hi, I am using the OpenMPI v1.4a1r22335 to run an MPI application that creates dynamically processes. The application behavior is like explained in a previous e-mail http://www.open-mpi.org/community/lists/users/2009/12/11540.php The application is launched by a command line such as: $ mpirun

[OMPI users] error performing MPI_Comm_spawn

Hi, I intend to develop an application using the MPI_Comm_spawn to create dynamically new MPI tasks (or processes). The structure of the program is like a tree: each node creates 2 new ones until reaches a predefined number of levels. I developed a small program to explain my problem as can be se

[OMPI users] problems with MPI_Loockup_name

Hi, I am using the OpenMPI version 1.3 downloaded directly from the site. I want to establish a client/server connection among two local processes (in the same machine). I wrote a simple publisher combining MPI_Open_port / MPI_Publish_name / MPI_Comm_accept and a connector with MPI_Lookup_name /

[OMPI users] on-the-fly nodes liberation

Hi, May I sign one orted daemon to finish its execution on-the-fly? Context: I intend to use OpenMPI in a dynamic resource environment as I did with LAM/MPI helped by lamgrow and lamshrink commands. To perform grow operations (increase the amount of nodes/resources on-the-fly) OpenMPI enable an
