"A New Parallel Gauss-Seidel Method Based on Alternating Group Explicit Method and Domain Decomposition Method,"
by Rohallah Tavakoli and Parviz Davami
in Applied Mathematics and Computation, 188(1), pp. 713-719, Elsevier, May 2007To take advantage of the supercomputing resource with multiple processors, several parallel versions of the Gauss-Seidel (SOR) method have been proposed. In the present study, a new parallel Gauss-Seidel algorithm is developed based on domain decomposition and convergence iteration space alternate tiling method for solution of system of linear equations related to finite difference discretization of partial differential equations. The goal of this method is to improve three different performance aspects: inter-iteration data locality, intra-iteration data locality and parallelism. Intra-iteration locality refers to cache locality upon data reuse within convergence iteration, and inter-iteration locality refers to cache locality upon data reuse between convergence iterations.
