Comparisons of isoefficiency analysis and numerical experiments about CRS and ICRS methods

摘要：

In this paper, based the methods presented by Zhang et al. Conjugate residual square method and its improvement for nonsymmetric linear systems, Int. J. Comput. Math., accepted, 2009, we further study the performance of CRS and ICRS methods. However, we theoretically compare the isoefficiency analysis and make numerical experiments about CRS and ICRS methods which show that ICRS method has better parallelism and scalability than CRS method.
