If you had read the link you would have seen that it does use your own resources 
- that's why it is called a private cloud.  Or did you mean that CentOS should 
have an equivalent to match the Ubuntu configuration?  You probably could, but 
it would be a lot more work.

Distributed (super) computing normally involves techniques that break the work 
up into independent units.  If a node doesn't complete a unit it can be given to 
a different node.

Storage, on the other hand, needs to be reliable.  The hadoop project is an 
approach at distribution, but the interface is hard to deal with.
