[StarCluster] parallel ssh support?

[MacMullan, Hugh]

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.

Subject: [StarCluster] parallel ssh support?

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....
