<div class="gmail_quote">Hi Archie,<div>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.</div><div><br></div><div>The docs on</div><div>
<a href="http://web.mit.edu/stardev/cluster/docs/index.html" target="_blank">http://web.mit.edu/stardev/cluster/docs/index.html</a></div>
<div><br></div><div>haven't been updated in a while. There is a documentation page on starcluster in the code base, see </div><div>/starcluster/StarCluster/docs/sphinx/load_balancer.rst</div><div><br></div><div>That doc should have all of the information you need, and is readable in plain text.</div>
<div><br></div><div>Typically, this is how I fire up the load balancer:</div><div>starcluster bal <cluster_tag> -m <MAX_NODES you want> -n <MIN_NODES you want></div><div><br></div><div>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.</div>
<div><br></div><div>Hope that helps, and feel free to send back questions.</div><div>Rajat Banerjee</div><div><br><br><div class="gmail_quote"><div><div></div><div class="h5">On Fri, Jan 28, 2011 at 12:29 PM, <span dir="ltr"><<a href="mailto:starcluster-request@mit.edu" target="_blank">starcluster-request@mit.edu</a>></span> wrote:<br>
