The ARM11 does not pack much punch, there is no networking (though it should not be too difficult to add) and it is not even in production yet. But it does seem fun. Plus, $1000 would get you 40 units ...

I'm not sure it competes all that well compared to 48 core-per-U conventional servers (whether mips/flops or memory-based). here's an idea, more commodity-oriented (hence beowulf): suppose you design a tiny widget that gets all its power via POE. maybe Atom or ARM-based - you've got 15-20W, which is quite a bit these days. for packaging, you need space for a cpu, nic and sodimm. maybe some leds. plug them into a commodity 1U 48-port Gb switch, then stack 10 of them and you've got a penny-pincher's approximation of a Seamicro SM100000! not going to win top500, but... _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
