"Parallel Execution with Fabric"

For our July event, I'd like to hear about parallel command mechanisms; sometimes these are "parallel ssh" systems, or may be known as "orchestration systems." The typical use is to issue commands to lots of hosts in parallel. Examples include things like ppss (http://code.google.com/p/ppss/), Capistrano (https://github.com/capistrano/capistrano/wiki), Fabric (http://docs.fabfile.org/en/1.4.2/index.html), and Rundeck (http://rundeck.org/). Some folks are using these for everything, including application deployment. Some are only using them to augment deployment tools such as Chef, CFEngine, or Puppet in order to be able to issue commands to a fleet of hosts, which is something a lot of deployment tools aren't good at.
Do you use a parallel command system like one of these? Which one, and why? What do you use it for? How does the system deal with failures of single nodes? Do you have to do anything to handle these? Do you use this tool in combination with other tools to manage your infrastructure, or do you build everything around this tool?
I'm looking for 2-4 20-25 minute talks. If you can give a talk, please contact me, Chris Westin, through meetup.
As well as the evening's theme talks, we can fit in 2-3 five minute lightning talks at the beginning of the evening; any topic that would be interesting to the #lspe audience is welcome. If you're interested in giving a lightning talk, contact me, Chris Westin, through meetup.
