The World of Supercomputing Must Become Data Centric

For decades, it has been a commonly held belief that supercomputing capability is a predictable phenomenon with the "fastest" system in the world increasing in power by three orders of magnitude (1000X) about every 11 years. I put the term "fastest" in quotes, because very few ask the question: Fastest in what way? It turns out, of course, that this notion of "fastest" is limited to a narrow consideration of system performance that focuses on floating point capability.

The interesting thing about this is that, for many years, this notion of "fastest" was reasonably close to the notion of "most useful" as well. However, the linkage between speed and utility began to unravel several years ago without people paying much attention. About five years ago, a team from IB...
