| 英文摘要 | In this article, we give the convergence and consistency of the msd-cg method [gu, t.x., liu, x.-p., mo, z.-y. and chi, x.-b. (in press). multiple search direction conjugate gradient method 1: methods and their propositions. int. j. comput. math.] and estimate the convergence rate of this method. numerical experiments on two distributed parallel computers, dawning 3000 and p-ii cluster, show the efficiency of our method and show that it compares favorably with some domain decomposition methods. |
