Good insight. Thanks.

Interesting that the vector nodes have dramatically more flops, and hugely better scalar performance, but essentially the same network bandwidth per node and memory bandwidth per processor of the original Earth simulator from 20 years ago. One wonders if there are a lot of codes whose performance is largely unchanged, though at a much lower price tag.
