IBM Cold War Supercomputer Offers 200x Speed Lesson for AI Hardware

The declassification of IBM’s "Harvest" supercomputer, which ran for the NSA from 1962 to 1976, provides a critical new perspective on purpose-built AI hardware. At its peak, Harvest was up to 200 times faster than any general-purpose machine by pioneering real-time stream processing, a modular add-on architecture, and an automated tape library. Its existence reframes the narrative around specialized compute, revealing that the core concepts behind today’s AI accelerators aren
