The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. Announced in 1975, the first Cray-1 system was installed at Los Alamos National Laboratory in 1976. Eventually, eighty Cray-1s were sold, making it …

In 2019, HPE acquired Cray and with it opened a new chapter in a vibrant, ongoing supercomputing journey. The Cray-1 was the world’s fastest supercomputer from 1976 to 1982. It measured 8½ feet wide by 6½ feet high and contained 60 miles of wires.

It reigned as the world’s fastest from 1976 to 1982. Its distinctive design reflected Seymour Cray’s innovative engineering solutions and theatrical flair. The round tower minimized wire lengths, while the distinctive bench concealed power supplies.

The Cray-1 series of computers were manufactured from 1976 till 1983. About 60 of these machines were delivered to customer locations all over the world. At the time, they were the undisputed highest performing computers for scientific workloads. The Cray-1 system had the peripherals attached to the mainframe. The Cray-1S introduced the Input ...

His company’s first supercomputer, the Cray-1, which came out in 1976, could perform 240 million calculations per second. It was used for large-scale scientific applications, such as simulating complex physical phenomena, and was sold to government and university laboratories.

When it was finished in 1975, the Cray-1 was the fastest supercomputer in the world, its sixty miles of coiled wire processing data ten times more efficiently than its closest competitor. Fitting for such a revolutionary machine, Cray-1’s namesake was a …
