looks like a good article. i setup ClusterKnoppix yesterday on our home network, and it was a breeze!
1.boot one computer from CD and start the clustering server (in the icon menu, bottom left).
2.reboot all the computers in your network, changing boot sequence in bios to network (they will boot over the network).
it REALLY is that easy! parallelknoppix is probably just as simple. here's a big plug for anyone who's curious... download and burn the iso and experiment. you'll be glad you did
ps you can click "configure and restart" for the cluster server and click the radio box to add support for non-standard network cards if needed (i had a couple in my house, and one computer that can't network boot...i used it as the master node).
anyway... clusters are easier than they seem, and great fun. here's to coding in parallel
edited: "clustering server" should read "terminal server" in the sequence above.
