SSHWorker() — create a worker on a remote host accessed via ssh

SSHWorker(nodename, ssh_command='ssh')
This creates a new worker process running on a remote host given by nodename, started using 'ssh'. You can change the command used to start processes from ssh to, for example, 'rsh', with the ssh_command parameter. For most applications, you would need to set up passwordless rsh or ssh for this to be useful.
