| 英文摘要 | It was proposed that a robust and efficient parallelizable preconditioner for solving general sparse linear systems of equations, in which the use of sparse approximate inverse (ainv) techniques in a multi-level block ilu (bilum) preconditioner were investigated. the resulting preconditioner retains robustness of bilum preconditioner and has two advantages over the standard bilum preconditioner : the ability to control sparsity and increased parallelism. numerical experiments are used to show the effectiveness and efficiency of the new preconditioner. |
