Hi Archie,<div>I believe you are correct. I can't find the date on which 0.91.2 was cut, but if it doesn't have the "bal" or "loadbalance", then you're not running new enough code. </div><div>
<br></div><div>That can be rectified if your admin installs with these directions:</div><div><a href="http://web.mit.edu/stardev/cluster/docs/installation.html#install-development-version-from-github">http://web.mit.edu/stardev/cluster/docs/installation.html#install-development-version-from-github</a></div>
<div><br></div><div>And the result should look something like this:</div><div><br></div><div><div>$ starcluster bal</div><div>Leopard libedit detected.</div><div>StarCluster - (<a href="http://web.mit.edu/starcluster">http://web.mit.edu/starcluster</a>) (v. 0.9999)</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>
