Ordering Methods for Preconditioned Conjugate Gradient Methods Applied to Unstructured Grid Problems

SIAM Journal on Matrix Analysis and Applications, 1992
The authors study the influence of various ordering techniques on the quality of the incomplete LU factorization used in the conjugate gradient method as preconditioner. They develop an ordering technique ( minimum discarded fill ordering) that is especially suited for finite element equations on unstructured grids. Applications to anisotropic problems

Efficient Parallelization of the Preconditioned Conjugate Gradient Method

2009
In this paper we present methods for efficient parallelization of the solution of pressure Poisson equation arising in 3D CFD forest fire modeling. The solution procedure employs the Conjugate Gradient method with implicit Modified ILU (MILU) preconditioner.

Efficient Implementation of a Class of Preconditioned Conjugate Gradient Methods

SIAM Journal on Scientific and Statistical Computing, 1981
The preconditioned conjugate gradient (PCG) method is an effective means for solving systems of linear equations where the coefficient matrix is symmetric and positive definite. The incomplete $LDL^t $ factorizations are a widely used class of preconditionings, including the SSOR, Dupont-Kendall-Rachford, generalized SSOR, ICCG(0), and MICCG(0 ...
