International conference for High Performance Computing, Networking, Storage and Analysis (SC)

We present results of performance optimization for direct numerical simulation (DNS) of wall bounded turbulent flow (channel flow). DNS is a technique in which the fluid flow equations are solved without subgrid modeling. Of particular interest are high Reynolds number (Re) turbulent flows over walls, because of their importance in technological applications. Simulating high Re turbulence is a challenging computational problem, due to the high spatial and temporal resolution requirements. An optimized code was developed using spectral methods, the method of choice for turbulent flows. Optimization was performed to address three major issues: efficiency of banded matrix linear algebra, cache reuse and memory access, and communication for the global data transposes. Results show that performance is highly dependent on characteristics of the communication network, rather than single-core performance. In our tests, it exhibits approximately 80% strong scaling parallel efficiency at 786K cores relative to performance on 65K cores.

International conference on numerical methods for Hyperbolic Equations: theory and applications

In living organisms, fingering structures are often observed in open systems such as growing bacterial colonies, or in porous media flows as oil and gas reservoir. Viscous fingering phenomenon classically occurs when a less viscous fluid displaces a more viscous one in a porous media. We investigate numerically how the instability can be triggered by a simple reaction-diffusion flow. In order to perform our simulations we employed two solutions with different viscosities reacting in the interface and generating a more viscous product. The properties of the fingering pattern observed in the region where the less viscous reactant pushes the more viscous product are studied as a function of the relevant parameters of the problem. © 2013 Taylor & Francis Group, London.

At the interface generated by mixing two miscible fluids, instabilities may be induced due to difference between the fluids densities and/or diffusion coefficients. These instabilities generate characteristic patterns that affect the mass transport between the two species. The Belousov-Zhabotinsky reaction is a chemical reaction in which, due to autocatalysis of its intermediaries and differences between diffusion coefficients, chemical oscillations and waves are generated that result in pattern formation when the reaction is carried out in a two-dimensional media. The aim of this study was to analyze the influence of a chemical reaction system on the instabilities when two fluids with different densities and diffusion coefficients react in a Hele-Shaw cell. All models involved in these phenomena were solved using commercial software Flow-3D ® v9.3.2. © 2013 Taylor & Francis Group, London.

numerical simulation of three-dimensional transient variably saturated flow

Subsurface flow is an important part of hydrological processes, from infiltration during rain events to surface-subsurface flow interactions in floodplains and hillslopes. Since subsurface flow may occur in unsaturated and saturated conditions, models which are able to represent such conditions in a continous fashion are necessary. Furthermore, adequate mass conservation in hydrological processes must account for the exchange of surface and subsurface water both in steady and unsteady cases. Hence, a model which allows to approximate the solution of transient variably saturated flow problems, aiming towards surface-subsurface interactions, has been developed. Flow in variably saturated soils is described by Richards equation. This highly non-linear PDE requires in most cases the use of numerical methods for its solution. The proposed numerical model allows for the solution of the water content and pressure distribution in three dimensional domains by means of an implicit finite volume scheme which adequately conserves mass and represents wetting fronts both in time and space. The model has been developed progresively from one to three dimensions, testing it against an analytical solution of an infiltration problem and by means of test cases. In one dimensional form, several numerical schemes were tested to determine the best numerical approach and determine the response of the model to different configurations and parameters. Validation against the analytical solution shows that the model is able to correctly solve Richards' equation in one, two and three dimensions. Test case solutions show good behavior of the model in all dimensions against particular geometries and different initial and boundary conditions. © 2013 Taylor & Francis Group, London.

Chaotic Optimization Method without Initial Sampling Parameter Tuning - Empirical Comparisons of Two Approaches in Various Problems

IEEE International conference on Systems, Man, and Cybernetics (SMC)

The chaotic optimization method is a global optimization method to solve unconstrained optimization problems. Its superior search capability has been confirmed through applications to optimization problems which have high dimensional and multi-peaked objective functions. However, the chaotic optimization method has a drawback in that a parameter called initial sampling parameter has to be tuned on each optimization problem. In this study, we consider two approaches to perform the chaotic optimization method without the initial sampling parameter tuning. One is the initial sampling estimation method based on the characteristics of the chaotic optimization method. In this method, the sampling parameter at which the search trajectory bifurcates from the fixed point convergence to the two periodic solution trajectory, which is called the first bifurcating parameter, is computed from the approximation matrix to Hessian obtained by the quasi-Newton method. Then, suitable initial sampling parameter is estimated using this information. The other is the descent sign vector method. In this method, a descent sign vector extracted from a gradient vector is used as a search direction of a search point. Then, its moving distance is determined so that its search process shifts from the global search to the local search. We compare two methods and their hybrid method through numerical experiments for various optimization problems.

This book collects up-to-date papers from world experts in a broad variety of relevant applications of approximation theory, including dynamical systems, multiscale modelling of fluid flow, metrology, and geometric modelling to mention a few. The 14 papers in this volume document modern trends in approximation through recent theoretical developments, important computational aspects and multidisciplinary applications. The book is arranged in seven invited surveys, followed by seven contributed research papers. The surveys of the first seven chapters are addressing the following relevant topics: emergent behaviour in large electrical networks, algorithms for multivariate piecewise constant approximation, anisotropic triangulation methods in adaptive image approximation, form assessment in coordinate metrology, discontinuous Galerkin methods for linear problems, a numerical analyst's view of the lattice Boltzmann method, approximation of probability measures on manifolds. Moreover, the diverse contributed papers of the remaining seven chapters reflect recent developments in approximation theory, approximation practice and their applications. Graduate students who wish to discover the state of the art in a number of important directions of approximation algorithms will find this a valuable volume. Established researchers from statisticians through to fluid modellers will find interesting new approaches to solving familiar but challenging problems. This book grew out of the sixth in the conference series on "Algorithms for Approximation", which took place from 31st August to September 4th 2009 in Ambleside in the Lake District of the United Kingdom.

With the rapid growth in available genomic data, robust and efficient methods for identifying RNA secondary structure elements, such as hairpins, have become a significant challenge in computational biology, with potential applications in prediction of RNA secondary and tertiary structures, functional classification of RNA structures, micro RNA target prediction, and discovery of RNA structure motifs. In this work, we propose the Forward Stem Matrix (FSM), a data structure to efficiently represent all k-length stem options, for k 2 K, within an n-length RNA sequence T. We show that the FSM structure is of size O(njKj) and still permits efficient access to stems. In this paper, we provide a linear O(njKj) construction for the FSM using suffix arrays and data structures related to the Longest Previous Factor (LPF), namely, the Furthest Previous Non- Overlapping Factor (FPnF) and Furthest Previous Factor (FPF) arrays. We also provide new constructions for the FPnF and FPF via a novel application of parameterized string (p-string) theory and suffix trees. As an application of the FSM, we show how to efficiently find all hairpin structures in an RNA sequence. Experimental results show the practical performance of the proposed data structures.

In this paper, we apply a method for extracting a running power estimate of applications from hardware performance counters, producing power/time curves which can be integrated over particular intervals to estimate the energy consumption of individual application stages. We use this method to instrument executions of a conjugate gradient solver, to examine the energy and performance impacts of applying the Compressed Sparse eXtended (CSX) and classic Compressed Sparse Row (CSR) matrix compression methods to sparse linear systems from different application areas. The CSX format requires a preprocessing stage which identifies and exploits a range of matrix substructures, incurring a one-time cost which can facilitate more effective sparse matrix-vector multiplication (SpMV). As this numerical kernel is the primary performance bottleneck of conjugate gradient solvers, we take the approach of isolating the energy cost of preprocessing from a short sample of application iterations, obtaining measurements which enlighten the choice of which compression scheme is more appropriate to the input data. We examine the impact variable degrees of parallelism, processor clock frequency, and Hyper threading have on this trade-off. Our results include comparisons of empirically obtained results from all combinations of up to 8 threads on 4 hyper threaded cores, 3 clock frequencies, and 5 sample application matrices. We assess program-hardware interactions with views to structural properties of the data and hardware architectural features, and evaluate the approach with respect to integrating the energy instrumentation with present automatic performance tuning. Results show that our method is sufficiently precise to identify non-trivial tradeoffs in the parameter space, and may become suitable for a run-time automatic tuning scheme by applying a faster preprocessing mode of CSX. © 2013 IEEE.

Analyzing Hogwild Parallel Gaussian Gibbs Sampling 13

Analyzing Hogwild Parallel Gaussian Gibbs Sampling

引用

Annual conference on Neural Information Processing Systems

作者： Matthew J. Johnson James Saunderson Alan S. Willsky EECS MIT

ISBN: (纸本)9781632660244

Sampling inference methods are computationally difficult to scale for many models in part because global dependencies can reduce opportunities for parallel computation. Without strict conditional independence structure among variables, standard Gibbs sampling theory requires sample updates to be performed sequentially, even if dependence between most variables is not strong. Empirical work has shown that some models can be sampled effectively by going "Hogwild" and simply running Gibbs updates in parallel with only periodic global communication, but the successes and limitations of such a strategy are not well understood. As a step towards such an understanding, we study the Hogwild Gibbs sampling strategy in the context of Gaussian distributions. We develop a framework which provides convergence conditions and error bounds along with simple proofs and connections to methods in numerical linear algebra. In particular, we show that if the Gaussian precision matrix is generalized diagonally dominant, then any Hogwild Gibbs sampler, with any update schedule or allocation of variables to processors, yields a stable sampling process with the correct sample mean.
