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

I concur. Threading for this? It's pretty non-intensive, just time-consuming. And adding/removing nodes can be pretty painful, as well, as it monkeys (serially) with /etc/hosts, keys, etc.<br>
