Hmm, the docs don't seem to be all that enlightening. Here is another way.
init_node is called for every node in the run method of a starcluster plugin
as well as in the on_add_node method of the plugin. HTH.

Regards,

Don


    def init_node(self, node, master):
        ...
        # Set the number of slots to 1. We do this so that only one job is
        # is submitted per machine, since we will use all of its available
        # threads in multi-threaded mode.
        cmd_strg = 'source /opt/sge6/default/common/settings.sh;' \
               'qconf -mattr exechost complex_values slots=1 %s' %
node.alias

        self.logger.debug("Executing: |%s|" % cmd_strg)
        output = master.ssh.execute(cmd_strg)
        ...
