<p class="MsoNormal" style="margin-bottom:12.0pt">Hi all - Whenever I launch a cluster with a large # of nodes, I have to wait quite a bit of time because each node has to be configured separately. The commands in my custom plugin are the same regardless of
machine. I was wondering if there was any support in StarCluster to use parallel-ssh to run the plugin on all the nodes at once? This could save a lot of start-up time....<u></u><u></u></p>
