Add to ORKGAbstract. 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 numer-ical properties and a potential for high parallel efficiency. In this note parallel performance of a circulant block-factorization based precondi-tioner applied to a 3D model problem is investigated. The aim of the presentation is to report on the experimental data obtained on SUN En
