CDC: The Dawning era of Supercomputers
1964: CDC 6600 (6xxx series)
The 6600 influenced architecture probably more than any other computer. It was well plumbed in every respect: it had tremendous bandwidth that interconnected all the components. All computer designers would do well to study it.
CDC built a number of compatible versions, including a dual processor. The 7600 was upward compatible and heavily pipelined. It was to be a prelude to the vector processor.
