نویسندگان
چکیده
Abstract Having considered the symbolic phase of a sparse Cholesky solver in previous chapter, focus this chapter is subsequent numerical factorization phase. If A symmetric positive definite (SPD) matrix, then it factorizable (strongly regular) and (in exact arithmetic) its = LL T exists. LDLT factorizations general indefinite matrices are Chapter 7 .

A latency tolerant hybrid sparse solver using incomplete Cholesky factorization
Consider the solution of large sparse symmetric positive de nite linear systems using the preconditioned conjugate gradient method. On sequential architectures, incomplete Cholesky factorizations provide effective preconditioning for systems from a variety of application domains, some of which may have widely di ering preconditioning requirements. However, incomplete factorization based precond...
متن کاملParallel Sparse Cholesky Factorization
Sparse matrix factorization plays an important role in many numerical algorithms. In this paper we describe a scalable parallel algorithm based on the Multifrontal Method. Computational experiments on a Parsytec CC system with 32 processors show that large sparse matrices can be factorized in only a few seconds.
متن کاملHighly Parallel Sparse Cholesky Factorization
We develop and compare several fine-grained parallel algorithms to compute the Cholesky factorisation of a sparse matrix. Our experimental implementations are on the Connection Machine, a distributedmemory SIMD machine whose programming model conceptually supplies one processor per data element. In contrast to special-purpose algorithms in which the matrix structure conforms to the connection s...
متن کاملModifying a Sparse Cholesky Factorization
Given a sparse symmetric positive definite matrix AAT and an associated sparse Cholesky factorization LDLT or LLT, we develop sparse techniques for obtaining the new factorization associated with either adding a column to A or deleting a column from A. Our techniques are based on an analysis and manipulation of the underlying graph structure and on ideas of Gill et al. [Math. Comp., 28 (1974), ...
متن کاملReducing Overhead in Sparse Hypermatrix Cholesky Factorization
The sparse hypermatrix storage scheme produces a recursive 2D partitioning of a sparse matrix. Data subblocks are stored as dense matrices. Since we are dealing with sparse matrices some zeros can be stored in those dense blocks. The overhead introduced by the operations on zeros can become really large and considerably degrade performance. In this paper, we present several techniques for reduc...
