Shifting technique vs. pointer structures in unsymmetric sparse linear equations systems solver

Abstract

The research reported in this paper presents a new idea of the storage structure of sparse matrices. This structure is used in the multi-option solver of linear equation systems with unsymmetrical sparse coefficient matrices. The new solver is compared comprehensively with the analogous (identical numerical method used) solver of the classical type. The tests of new solver have been performed on a quite broad spectrum of hardware platforms.
