Caltech Cosmic Cube

The Caltech Cosmic Cube was a parallel computer, developed by Charles Seitz and Geoffrey C Fox from 1981 onward.[1]

It was an early attempt to capitalise on VLSI to speed up scientific calculations at a reasonable cost. Using commodity hardware and an architecture suited to the specific task (QCD), Fox and Seitz demonstrated that this was indeed possible.

In 1984 a group at Intel including Justin Rattner and Cleve Moler developed the Intel iPSC inspired by the Cosmic Cube.[2] In 1987 several people in the group formed a company called Parasoft to commercialize the message passing interface developed for the Cosmic Cube.[3]
