Description

This is a color image of two men working on a terminal next to the ILLIAC IV computer. One man is sitting down and taking notes while looking at the screen. The other man is standing and typing. Written on the image in black pen is "Sent to Digital Computer Museum" and a black arrow is pointing to the middle of the image towards some black computer modules. Light is coming from the overhead ceiling.

Parallel Processing appeared in the huge ILLIAC IV, the first computer to abandon the classic one-step-at-a-time scheme of John von Neumann. ILLIAC IV had sixty-four processors, each with its own memory, all operating simultaneously on separate parts of one problem. Designed at the University of Illinois and built by Burroughs, the computer took six years to complete at a cost of $40 million. It was the fastest machine then in use, but ahead of its time. Plagued by technical ills and very difficult to program, ILLIAC IV was one of a kind.
