Jim,

I've used The Cluster Command and Control (C3) Tool Suite
http://www.csm.ornl.gov/torc/C3/index.html

It's really light-weight, no GUI, runs from the command line, and
has a really easy config file for defining your cluster. Once you
get the "ssh trust" environment setup, it's works very well.

It has commands like:
cpush A utility to push files from the local machine to the nodes in your cluster.
cshutdown A utility that runs shutdown on each cluster node.
cexec(s) A utility that executes a given command string on each node of a cluster.

In your situation, you could do a 'cexec cat /proc/cpuinfo' and it would run
the cat via ssh on each node and report to the console.

Although I've only run it against RedHat machines, I don't think
there would be much problems running it on YDL. It's only real
requirement is python2.

HTH
