程序代写代做代考 data structure js algorithm Chapter 1An Improved Algorithm for Parallel Sparse LUDecomposition on a Distributed-Memory MultiprocessorJacko Koster� Rob H. BisselingyAbstractIn this paper we present a new parallel algorithm for the LU decomposition of ageneral sparse matrix. Among its features are matrix redistribution at regular intervalsand a dynamic pivot search strategy that adapts itself to the number of pivots produced.Experimental results obtained on a network of 400 transputers show that these featuresconsiderably improve the performance.1 IntroductionThis paper presents an improved version of the parallel algorithm for the LU decompositionof a general sparse matrix developed by van der Stappen, Bisseling, and van de Vorst[9]. The LU decomposition of a matrix A = (Aij ; 0 � i; j < n) produces a unit lowertriangular matrix L, an upper triangular matrix U , a row permutation vector � and acolumn permutation vector �, such thatA�i;�j = (LU)ij ; for 0 � i; j < n:(1)We assume thatA is sparse and nonsingular and that it has an arbitrary pattern of nonzeros,with all elements having the same (small) probability of being nonzero. A review of parallelalgorithms for sparse LU decomposition can be found in [9].We use the following notations. A submatrix of a matrix A is the intersection of severalrows and columns of A. The submatrix A[I; J ], I; J � f0; : : : ; n � 1g, has domain I � J .If I = fig, we use A[i; J ] as shorthand for A[fig; J ]. The concurrent assignment operatorc; d := a; b denotes the simultaneous assignment of a to c and b to d. For any (sub)matrixA, nz(A) denotes the number of nonzeros in A. For any set I , jI j is the cardinality of I .Our algorithm is aimed at a distributed-memory message-passing MIMD multiprocessorwith anM �N mesh communication network. We identify each processor in the mesh witha pair (s; t), 0 � s < M , 0 � t < N . A Cartesian distribution [1] of A is a pair ofmappings (�; ) that assigns matrix element Aij to processor (�i; j), with 0 � �i < Mand 0 � j < N . For processor (s; t), the set I(s) denotes the local set of row indicesI(s) = fi : i 2 I ^ �i = sg. Similarly, J(t) = fj : j 2 J ^ j = tg.�CERFACS, 42 Ave G.
