The CDC 7600 was designed by Seymour Cray to be the successor to the CDC 6600, extending Control Data's dominance of the supercomputer field into the 1970s. [6] The 7600 ran at 36.4 MHz (27.5 ns clock cycle) and had a 65 Kword primary memory (with a 60-bit word size) using magnetic core and variable-size (up to 512 Kword) secondary memory ...

From 1968 to 1972, Seymour Cray of Control Data Corporation (CDC) worked on the CDC 8600, the successor to his earlier CDC 6600 and CDC 7600 designs. The 8600 was essentially made up of four 7600s in a box with an additional special mode that allowed them to operate lock-step in a …

The NCAR CDC 7600 was operated for nearly 12 years. NCAR augmented its computational capacity by acquiring the first production Cray-1A system – serial number 3 – in 1977. Those two systems served NCAR's computational needs until the 7600 was decommissioned and replaced in the spring of 1983 by a second Cray-1A – serial number 14.

Jul 28, 2017 · 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.

Jul 9, 2024 · Cray's innovative designs revolutionized modern supercomputing architectures by introducing vector processing, which significantly enhanced computational performance. His pioneering work on the CDC 7600, released in 1969, laid the foundation for subsequent generations of supercomputers.

Cray began work at Control Data Corporation soon after its founding in 1960 and remained there until 1972. He designed several computers, including the CDC 1604, CDC 6600, and CDC 7600. The CDC 1604 was intended just to be a good computer; all computers beginning with the CDC 6600 were designed for speed.

The 6600 central processor with its scoreboard-controlled out-of-order issue was innovative and is very well known, but the 7600 central processor, designed by Cray (Thronton had gone off to do the STAR-100) is probably a cleaner, more unified design than the 6600.

Seymour Cray was already at work on an innovative design for a machine 50 times faster than the CDC 1604, and Livermore happily acquired one of his CDC 6600 computers for $8 million in August 1964. Cray’s design team then further refined this approach, yielding the even larger and faster CDC 7600 in 1969. In the hands of Laboratory

Cray had a string of successes at CDC, including the CDC 6600 and CDC 7600. When CDC ran into financial difficulties in the late 1960s, development funds for Cray's follow-on CDC 8600 became scarce.
