Does anyone know of or remember seeing any public work on practical side of building hypercube'd clusters ?
the "Building Linux Clusters" book from O'Reilly uses hypercube topologies for interconnection in the example deployments detailed: http://www.oreilly.com/catalog/clusterlinux/ it's a bit dated at this point, but still informative.
Specifically, I'm curious about two things - dynamic restructuring of the cluster in the event of the connectivity loss between its nodes and the handling of non-2^n nodes case.
the examples in the book used cross-over direct connections between nodes to avoid switching latencies. if you need to support dynamic restructuring you're going to have to throw a nice switch fabric (or a few of them) in there, and utilize a much more complicated geometry to retain the benefits of hypercube inter connectivity while avoiding bottlenecks at switching points. you may want to look at Myrinet if you need such switching capabilities, though this somewhat obviates the need for a hypercube geometry: http://www.myri.com/myrinet/overview/ _______________________________________________ p2p-hackers mailing list [email protected] http://lists.zooko.com/mailman/listinfo/p2p-hackers
