In May 1960, Remington Rand delivered the building-size Livermore Advanced Research Computer that had been built to Lawrence Livermore National Laboratory's specifications. The machine was 175 times more powerful than the UNIVAC I. The UNIVAC LARC, short for the Livermore Advanced Research Computer, is a mainframe computer designed to a requirement published by Edward Teller in order to run hydrodynamic simulations for nuclear weapon design. It was one of the earliest supercomputers. It was the fastest computer in 1960-61, until the IBM 7030 took the title. No photographer credited, dated 1960.
