You need to configure 'passwordless ssh' Can we assume that your home directory is shared across all cluster nodes? That means when you log into a cluster node the directory which is your Unix 'home directory' has exactly the same files as on the cluster head node? Then you need to configure passwordless ssh Use this as a starting point: http://www.open-mpi.org/faq/?category=rsh#ssh-keys
