CONCEPTS FOR EFFICIENT MULTIGRID IMPLEMENTATION ON SUPRENUM-LIKE ARCHITECTURES
收藏 引用
PARALLEL COMPUTING 1991年 第1期17卷 1-16页
作者: ALEF, M Kernforschungszentrum Karlsruhe GmbH Abteilung Numerische Physik (HDI 3) Postfach 36 40 W-7500 Karlsruhe 1 Germany
The implementation of algorithms on distributed-memory multiprocessors requires regular exchange of certain intermediate results between the parallel processes. The less data that must be moved the more efficient the ... 详细信息

A PARALLEL ALGORITHM FOR GENERATING DISCRETE ORTHOGONAL POLYNOMIALS
收藏 引用
PARALLEL COMPUTING 1992年 第6期18卷 649-659页
作者: EGECIOGLU, O KOC, CK UNIV HOUSTON DEPT ELECT ENGNHOUSTONTX 77204 UNIV CALIF SANTA BARBARA DEPT COMP SCISANTA BARBARACA 93106
A parallel algorithm that makes use of the classical three-term recursion formula to construct an orthogonal family of polynomials with respect to a discrete inner product is proposed. The algorithm requires O(N log N... 详细信息

Exploitation of image parallelism for ray tracing 3D scenes on 2D mesh multicomputers
收藏 引用
PARALLEL COMPUTING 1997年 第13期23卷 1993-2015页
作者: Lee, TY Natl Cheng Kung Univ Dept Comp Sci & Informat Engn Tainan 70101 Taiwan
Ray tracing is a well known technique to generate life-like images based on models of light shading, reflection, and refraction. The massive computation and memory demands of ray tracing complex scenes have long motiv... 详细信息

Parallel p-adic method for solving linear systems of equations
收藏 引用
PARALLEL COMPUTING 1997年 第13期23卷 2067-2074页
作者: Koc, CK Oregon State Univ Dept Elect & Comp Engn Corvallis OR 97331 USA
We present a parallel algorithm for an exact solution of an integer linear system of equations using the single modulus p-adic expansion technique. More specifically, we parallelize an algorithm of Dixon, and present ... 详细信息

A MULTILEVEL DIFFUSION METHOD FOR DYNAMIC LOAD BALANCING
收藏 引用
PARALLEL COMPUTING 1993年 第2期19卷 209-218页
作者: HORTON, G Lehrstuhl f&uuml r Rechnerstrukturen Universit&auml t Erlangen-N&uuml rnberg Martensstr. 3 8520 Erlangen Federal Republic of Germany
We consider the problem of dynamic load balancing for multiprocessors, for which a typical application is a parallel finite element solution method using non-structured grids and adaptive grid refinement. This type of... 详细信息

Minimum communication cost reordering for parallel sparse Cholesky factorization
收藏 引用
PARALLEL COMPUTING 1999年 第8期25卷 943-967页
作者: Lin, WY Chen, CL IShou Univ Dept Informat Management Kaohsiung Taiwan Natl Taiwan Univ Dept Comp Sci & Informat Engn Taipei 10764 Taiwan
In this paper, we consider the problem of reducing the communication cost for the parallel factorization of a sparse symmetric positive definite matrix on a distributed-memory multiprocessor. We define a parallel comm... 详细信息

SUPERNODAL SYMBOLIC CHOLESKY FACTORIZATION ON A LOCAL-memory multiprocessor
收藏 引用
PARALLEL COMPUTING 1993年 第2期19卷 153-162页
作者: NG, E Mathematical Sciences Section Oak Ridge National Laboratory P.O. Box 2008 Bldg. 6012 Oak Ridge TN 37831-6367 USA
In this paper, we consider the symbolic factorization step in computing the Cholesky factorization of a sparse symmetric positive definite matrix on distributed-memory multiprocessor systems. By exploiting the superno... 详细信息

PARALLEL COMPUTING 1993年 第3期19卷 243-256页
作者: CHU, E GEORGE, A QUESNEL, D UNIV WATERLOO DEPT COMP SCIWATERLOO N2L 3G1ONTARIOCANADA
In this paper we propose a new medium-grain parallel algorithm for computing a matrix inverse on a hypercube multiprocessor. The algorithm implements Gauss-Jordan inversion with column interchanges. The hypercube netw... 详细信息
