    A new multiscale approach for simulating nanobiological flows uses concurrent coupling of constrained molecular dynamics for long biomolecules with a mesoscopic lattice Boltzmann treatment of solvent hydrodynamics. The approach is based on a simple scheme of space- time information exchange between the atomistic and mesoscopic scales. View full abstract»

    The authors describe a data exploration system that visualizes time-varying, multivariate, point-based data from gyrokinetic particle simulations. By using two interaction modes, their system lets researchers explore collections of densely packed particles and discover interesting aspects, such as the location and motion of particles trapped in turbulent plasma flow.

    The semi-implicit integration scheme for simulating cloth animation can introduce vibrations, which increase the number of iterations and produce other unwanted outcomes. The authors' new model efficiently simulates cloth animation yet introduces fewer artificial damping effects than previously proposed methods. View full abstract»

    The program tool Thermath now lets researchers automatically generate complete, ready-to-use Matlab functions. The examples here deal with critical-point calculations and the development of equipment models for separations in the chemical industry, but the ability to automatically generate Matlab functions is useful in many areas of science and engineering.

    Internet-based technologies can supplement traditional laboratories with remote or simulated experimentation sessions. The authors describe their virtual and remote laboratory, which uses a nonlinear system that students can run from anywhere on the Internet. The implementation integrates both open source and commercial software tools. View full abstract»

    A good benchmarking methodology can save a tremendous amount of resources in terms of human effort, machine cycles, and cost. Such a methodology must consider the relevance and openness of the chosen codes, well-defined rules for executing and reporting the benchmarks, a review process to enforce the rules, and a public repository for the obtained information. For the methodology to be feasible, it must also be supported by adequate tools that enable the user to consistently execute the benchmarks and gather the requisite metrics. At the very least, reliable benchmarking results can help people make decisions about HPC acquisitions and assist scientists and engineers in system advances. By saving resources and enabling balanced designs and configurations, realistic benchmarking ultimately leads to increased competitiveness in both industry and academia. View full abstract»

    The paper shows how applying knowledge about the underlying computer hardware to the code for a simple but computationally intensive algorithm can significantly improve performance. The paper also discusses how to rearrange code so that it accommodates the peculiarities of the memory system and consequently reduces execution time. View full abstract»

  • Numerical Simulation of Wave Propagation, Part II: Parallel Computing

    Publication Year: 2008 , Page(s): 76 - 83

    In the first part of this series,' we described the most commonly used methods for numerically solving wave propagation in heterogeneous media with a single processor. However, if we want to perform such simulations for large-scale media, computations on single processors can quickly become prohibitively expensive. This is particularly true for elastic waves because we must compute at least three field variables at each node of a three-dimensional grid. Consequently, many research efforts have focused on developing massively parallel strategies for large numbers of processors; the purpose of this article is to provide an overview of what this research has accomplished so far. In the second part of a two-part series, the authors discuss massively parallel strategies for numerically solving wave propagation in heterogeneous media. View full abstract»

    Are high-resolution digital holographic displays just around the corner? In the 1990s, two hurdles seemed to be preventing the practical implementation of computational holography techniques: computational workload and hardware projection capabilities. Are these hurdles still in place? View full abstract»
