We have tried maintaining that balance with Caos Linux, and focusing
now on Caos NSA (Node Server Appliance) which makes it a decent HPC
solution (at least that is what we are going for) for many of the

Warning, it is not intended to be anything aside from a cluster/server
type of solution so don't try it on your laptop. ;)
