The National Magnetic Fusion Energy Computer Center was formed in 1974 under the name Controlled Thermonuclear Research Center to meet the significant computational demands national magnetic fusion research being done at Lawrence Livermore National Laboratory. In 1983 the center's role was expanded to include the full range of national energy research programs. The name later changed to the National Energy Research Supercomputer Center (NERSC) and moved to Berkeley. The center first ran on CDC-7600 machines. In 1978, the Center acquired one of the first Cray I's, followed by a series of ever more powerful Crays. The Cray-1 was a supercomputer designed, manufactured and marketed by Cray Research. The first Cray-1 system was installed at Los Alamos National Laboratory in 1976 and it went on to become one of the best known and most successful supercomputers in history. The Cray-1's architect was Seymour Cray, the chief engineer was Cray Research co-founder Lester Davis. No photographer credited, dated 1983.
