Abstract :
The Los Alamos and Lawrence Livermore National Laboratories have been important sponsors of, and customers for, supercomputers-high-performance scientific computers. The laboratories played an important part in establishing speed of floating-point arithmetic (rather than, say, at logical operations) as the performance criterion defining supercomputing. But their more specific influence on the evolution of computer architecture has been limited by the diversity and classified nature of their central computational tasks, together with the expansion of supercomputer use elsewhere.
