  author={Jae Heon Yun},
  journal={Numerische Mathematik},
In this paper, we study the convergence of multisplitting methods associated with a multisplitting which is obtained from the ILU factorizations of a general H -matrix, and then we propose parallelizable ILU factorization preconditioners based on multisplittings for a block-tridiagonalH -matrix.We also describe a parallelization of preconditioned Krylov subspace methods with the ILU preconditioners based on multisplittings on distributed memory computers such as the Cray T3E. Lastly, parallel… CONTINUE READING
