Hi Carsten
It has to be a HPC cause it's a given challenge: "Build a Linux HPC
with ethernet"

But i can handle nearly every Linux distribution, so I'm free in that
point. Depends on which distribution the needed software is running.
there are 7 sun fire x4000 with ethernet (infiniband would get to expensiv).

I don't need much storage, but I could use NAS if needed.
I see ;)

to that. That's typically it ;)
My imagination is, that you upload this script to a master node, which
splits it up and distributes the parts to its nodes.
hope you can understand :)
What do you think? Still possible to do that with Beowulf?
