That issue I see it by another point of view: finally I will learn something really new. Yes, I will loose time but I hope that in the end all players will win: me because I got money and know how and the cluster users because we doubled the capacity (not really because I don't believe that mixing the nodes will possible) so more people can run code. But the question remains unanswered ;) and is not tied to the "heterogeneous cluster" problem: If diskless what about "/var" like issues; if not, what do you use to install and manage it Gil Brandao _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
