Abstract
The parallelizable block ILU (incomplete LU) factorization preconditioners for a block-tridiagonal matrix have been recently proposed by the author. In this paper, we describe a parallelization of Krylov subspace methods with the block ILU factorization preconditioners on distributed-memory computers such as the Cray T3E, and then parallel performance results of a preconditioned Krylov subspace method are provided to evaluate the effectiveness and efficiency of the block ILU preconditioners on the Cray T3E.
