[Beowulf] noobs: what comes next?

[Douglas Eadline]

If you want to build a small cheap usable cluster check this out.

  http://limulus.basement-supercomputing.com/

The project is moving a little slow, but that is because
I have been working on packaging everything (16 cores
using quads) in one case with one power supply.
(more on the project page)

Some software announcements will be forthcoming as well.

Actually, I think of it as more of a parallel workstation
than a production cluster.
