Are the nodes fully-interconnected with InfiniBand? Yes. If you buy 10 nodes, you’ll get a 10 node cluster with 3.2tb/s IB. How fast is the spin up time? About 0.5s.

The Sapient paradox is a question that can be formulated as "why there was such a long gap between emergence of genetically and anatomically modern humans and the development of complex behaviors?" Homo sapiens emerged as a species somewhere between 60,000 and 100,000 (or even 200,000) years ago, but the behaviour that is associated with modern humans began to emerge and accelerate only 10,000 years ago.
