Hi,
There is no mpd in Open MPI. mpirun will spawn everything needed for
you. Make sure all your processes call MPI_Init, and not only the root
process. If you mpirun -np 10, 10 processes need to go trough MPI_Init
to allow for further progression.
If this does not solve you problem, please give the Open MPI version
(ompi_info gives it) and check your installation does not collide with
another installation of MPICH or LAM.

Hi,
I tried to run a hello world example of mpi code. It just hangs at
MPI_Init. My machine is installed with Ubuntu linux and I install some
package of open mpi. Compiling was okay, but running the code hangs at
MPI_Init. Is there any specific things that I should do before running
mpi code such as "mpd" setup?
I will appreciate any help.
Thank you,
Sang Chul
