On still other sides, "supercomputers are clusters".
We should probably differentiate between vector supercomputers (Greg's
point, which is well taken) and e.g. SP supercomputers, which are
basically clusters. Really expensive clusters, but clusters.
My observation about elephants, oxen vs chickens was more towards the
supercomputers that are just very expensive clusters, not the
vector/linear algebra engines.
Although the metaphor is obviously now strained well past the breaking
