Seymour Cray: The Man Who Brought Style to Supercomputers

Photo: Mark Richards/Computer History Museum A supercomputer is simply a computer that can perform many more calculations per second than the typical computer of its era. The definition is in constant flux: Yesterday’s supercomputer packed the punch of today’s smartphone. From 1969 to 1975, Control Data Corp. ’s CDC 7600 was considered the world’s fastest computer, running at 36 megahertz. An iPhone 7, by contrast, runs at 2.33 gigahertz—nearly 100 times as fast as the 7600. The CDC 7600 was the brainchild of Seymour Cray , who from the 1950s through the 1980s was the undisputed champion among supercomputer designers. Working from a rural laboratory in his hometown of Chippewa Falls, Wisc., Cray had also designed the 7600’s predecessor, the CDC 6600. Each 7600 had thousands of electronic modules, each built from individual transistors and interconnected with more than 190 ...
