[Beowulf] Is Beowulf the right solution for my problem ?

Personally, I'd recommend using oneSIS (http://onesis.org).  It is
extremely easy to setup/maintain, and doesn't force you into a minimal
root filesystem (like warewulf).  It sits on top of any linux
distribution, and it is very easy to deal with.  Simply put, it is
simpler, easier to use, and more flexible than any other cluster
management software I know of.
