Sci. 39, No. 6, 1-3,62 (2011). 2011 Henan Normal University, Xinxiang, Henan ZH sparse unsymmetrical linear systems Krylov subspace method ICGS method global communication distributed parallel computing Summary: In this paper, an improved ICGS method is proposed for parallel distributed memory environments. The improved ICGS method only reduces one inner product, but has better parallel efficiency than the ICGS method. Numerical experiments show that the improved ICGS method has better parallel efficiency than the ICGS method.
