TECH SPEC TUESDAY Cray-1 About this machine: First installed at Los Alamos National Laboratory in 1976, the Cray 1 was a supercomputer that was designed and manufactured by Cray Research, led by Seymour Cray. It was the first supercomputer to implement a vector processor design which allowed it to perform a single operation on a large dataset. Priced from $5 million to $8 million each, Cray sold over 80 of the machines, solidifying both Seymour Cray’s and his company’s reputation for excellence and leading the supercomputing industry.
