Have you tried the command ompi_info? What is its output? Furthermore, the command you gave > mpirun -np 2 --hostfile /home/stephan/mpd.hosts is incomplete. There is no executable.
Try to make sure wether your host file has the correct format. If i remember correctly Open-MPI does not use the same format for hostfiles as MPICH. See the FAQ for more info http://www.open-mpi.org/faq/?category=running#mpirun-scheduling If you don't use a hostfile, mpirun will start all processes on the local machine. jody On Tue, Apr 22, 2008 at 8:56 AM, <gildo....@gmx.de> wrote: > Dear all, > > I wanted to compare MPICH and OpenMPI.
