What the system is saying is that (a) you don't have transparent ssh authority on one or more of your nodes, and/or (b) the system was unable to locate the Open MPI code libraries on the remote node. For the first problem, please see the FAQ at:
http://www.open-mpi.org/faq/?category=rsh#ssh-keys Once you have that fixed, then you should check the remote nodes to ensure that the Open MPI code libraries are available - you may need to provide a prefix directory to mpirun to tell us where they are. Please see the FAQ at: http://www.open-mpi.org/faq/?category=running For some advice in that area.
