John Gustafson
Programming the FPS T Series

This tech note is significant for two reasons... one is that it shows Gustafson had fleshed out the concept of scaled speedup long before the Sandia results made it well-known. The other is that Gustafson proposed that supercomputers should be constructed by filling a building with low-cost cabinets based on commodity VLSI, connected by message passing. This view was greeted with laughter at the time, but was prescient; now, every large-scale computer uses this approach.
