High Performance Computing

LANL has been at the forefront of scientific computing since before the invention of electronic computers. For several decades it collaborated with industry on the development of large-scale computers and in the early 1990's helped initiate the shift to massively parallel computing. LANL also pioneered the development of powerful algorithms for computations and simulations in the physical sciences. Beginning with a tutorial explaining how computers work, this volume covers some of LANL's best known software contributions, including a Monte Carlo code for particle transport, molecular dynamics software for materials science, and advanced tree codes for simulating the evolution of the universe. Finally, Paul Ginsparg, the creator of xxx.lanl.gov, discusses the motivation for the first electronic research archive.
