Saltstack and even Python Fabric are great tools for managing large
numbers of systems. I have not used them with a Beowulf system yet but
the threading and logging for "push" configurations is the best of
both worlds. One great aspect of Python Fabric is the local command
execution so that things like RSH, TFTP and Telnet are possible with
your deployment/configuration system.
