Abstract

It was recently shown that block-circulant preconditioners applied to a conjugate gradient method used to solve structured sparse linear systems arising from 2D or 3D elliptic problems have good numerical properties and a potential for high parallel efficiency. In this note parallel performance of a circulant block-factorization based preconditioner applied to a 3D model problem is investigated. The aim of the presentation is to report on the experimental data obtained on SUN Enterprise 3000, SGI/Cray Origin 2000, Cray J-9x, Cray T3E computers and on two PC clusters.
