Hi Archie,
Yes, there is ELB built into the latest releases of StarCluster. I wrote it,
so feel free to write me (+ the list) with any questions.

The docs on

haven't been updated in a while. There is a documentation page on
starcluster in the code base, see

That doc should have all of the information you need, and is readable in
plain text.

Typically, this is how I fire up the load balancer:
starcluster bal <cluster_tag> -m <MAX_NODES you want> -n <MIN_NODES you

It will poll the cluster every 60 seconds and make decisions. The decisions
are described in load_balancer.rst. There is a visualizer which makes 6
graphs with matplotlib to show you how many nodes are working, how many jobs
are running, queued, avg load, etc, but the visualizer still needs a little
bit of work.

Hope that helps, and feel free to send back questions.
