We use our own tool "Dolly" to clone cluster nodes. The tool is not
very user friendly (lack of time to work on it :-( , therefore we use
simple config-files (one per cloning-operation)), but it does fast
clones to any number of nodes, where the speed is independant on the
number of nodes (e.g. 2 GB partition to 24 machines takes < 4 minutes).

For more information, see the README-File:

We presented a paper at EuroPar 2000. Information about the paper as
well as the source for the tool can be found on:
