My guess is that mpirun tries to setup the connection to all nodes (every cpu core is counted as a single node) and fails. OpenMPI may use different methods for connection to nodes - ssh, rsh, shared memory etc. In your case it looks like trying rsh - this is AFAIK default OpenMPI behaviour. Read OpenMPI docs about running with e.g. shared memory (should be fastest) or over ssh (but then you have to install and configure ssh). Or you can also install rsh.
