    Maps are not reserved for geography. Chemical reactions, atomic diffusion and protein folding all involve atomic displacements determined by the topography of a complex energy landscape. These landscapes are largely unexplored, and our first priority is to identify their key features: the energy minima and the connecting paths between them. Such a study represents a formidable task. The effort nee... View full abstract»

    The authors aim to automatically interface C++ and Fortran 95 code, with either language playing the role of main and with user-defined types from one language available in the other. To physically interface C++ and Fortran 95 they: ensure that procedure names are visible and sensible across the language interface; reduce procedure arguments to the common set of built-in types available in both la...

    Astronomy is about to undergo a major paradigm shift, with data sets becoming larger and more homogeneous, designed for the first time in a top-down fashion. The paper discusses the Sloan Digital Sky Survey. By digitally mapping half of the northern sky, this project promises to radically improve the way scientists do astronomy. In putting a digital sky on the desktops of astronomers, the SDSS cou... View full abstract»

  • Computer algebra takes on the vibrating-membrane problem

    Publication Year: 1999, Page(s):88 - 93

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (376 KB)

    The vibrating membrane is a classic problem of mathematical physics. It provides a particularly good example of how a computer algebra system (CAS) can serve as a pedagogic tool for scientific analysis. In this article, we focus on the oscillation of a circular membrane. We concentrate on the pedagogical aspects and on the part of the theory in which a CAS can be the most helpful. Maple is an appr... View full abstract»

    Simulations run on the largest available parallel supercomputers are answering the question of how today's rich cosmic structure developed from a smooth, near featureless early universe. The paper presents two such simulations which illustrate how algorithm and implementation strategies can be optimized for specific cosmological problems. The first aims to outline structure in the largest possible... View full abstract»

    Computational science's driving force has been and will continue to be the steady and rapid growth in available raw computing power. This growth exceeds anything else witnessed in the history of technology. The challenge for the 21st Century is to exploit properly this enormous potential. Several fairly obvious directions of development can (and do) present great technical challenges, but the auth... View full abstract»

  • A jump on visualization: the bottom-up approach

    Publication Year: 1999, Page(s):83 - 87
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (420 KB)

    Visualization-using computer graphics to gain insight into complex phenomena-is a powerful tool for scientific computing, but visualization experts and computational scientists seem to live in separate worlds. Recently, however, the gap between these two worlds has narrowed, and scientific visualization has come to represent the marriage of supercomputing and graphics. Computer graphics provides t...

    The authors address the challenge of extracting high-precision measurements of cosmological parameters from upcoming megapixel cosmic-microwave data sets. They discuss the computational challenges associated with current methods for going from the time streams to multifrequency sky maps, from these maps to the different sky signals, and from there to the statistical properties of the cosmic microw...

    The next decade will be an exciting time for computational physicists. After 50 years of being forced to use standardized commercial equipment, they will finally be able to adapt their computing tools to their own needs. The first step in this breakthrough is the widespread availability of programmable chips that allow virtually every computational scientist to design his or her own special-purpos...

    Since the first successful treatment of a cancer patient with radiation a century ago, shortly after the discovery of X rays, radiation therapy has become more sophisticated. It now relies heavily on the use of computers to control X-ray or other particle sources, map the tumor's site with computed tomography (CT) or magnetic resonance imaging (MRI), and plan the safe use of multiple, intersecting...

    There has been a great leap forward in large scale molecular dynamics simulations due to both the growing availability of massively parallel supercomputers and the algorithmic work on parallel neighbor-list and cell-based MD codes. Simulations involving tens or hundreds of millions of atoms have gone from being a computational curiosity to being a routine scientific tool used to study diverse phen... View full abstract»
