People build multi-thousand node clusters like that. In the HPC world, oil-and-gas and some other industrial applications don't need more than 1 gbit. Of couse these days they use 10 gbit to connect 1gbit switches. In the non-HPC world, companies with huge datacenters often have thousands to many thousands of nodes in a single layer-2 network with 1gbit to the nodes. That's limited only by the size of the mac addr tables in your switches. When you have to split your cluster into layer-3 chunks, the bandwidth between chunks sucks, but most clusters in the non-HPC world are limited to 2000-4000 nodes anyway by various software limitations. -- greg _______________________________________________ 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
