Hi Archie,
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.
That can be rectified if your admin installs with these directions:
http://web.mit.edu/stardev/cluster/docs/installation.html#install-development-version-from-github
And the result should look something like this:
$ starcluster bal
Leopard libedit detected.
StarCluster - (
http://web.mit.edu/starcluster) (v. 0.9999)
Software Tools for Academics and Researchers (STAR)
Please submit bug reports to starcluster_at_mit.edu
Usage: loadbalance <cluster_tag>
Start the SGE Load Balancer.
starcluster: error: please specify a <cluster_tag>
rbanerjee:/opt/pose/core [SVN: /main/core/trunk]
$ starcluster loadbalance
Leopard libedit detected.
StarCluster - (
http://web.mit.edu/starcluster) (v. 0.9999)
Software Tools for Academics and Researchers (STAR)
Please submit bug reports to starcluster_at_mit.edu
Usage: loadbalance <cluster_tag>
Start the SGE Load Balancer.
starcluster: error: please specify a <cluster_tag>
Best,
Rajat
