Hi! CLOWN - The CLuster Of Working Nodes Projekt built a Cluster of more than 512 Computers (IMHO 536). They used a Mini-Distribution derived from Debian GNU/Linux 2.0 aka hamm :-)
Seems that nobody has noticed here :-) For further Information: http://europium.oc2.uni-duesseldorf.de/cluster/ (sorry german only) -- Heute ist nicht alle Tage, ich komme wieder, keine Frage!!! Joerg
