Computing a block incomplete LU preconditioner as the by-product of block left-looking A-biconjugation process
In this paper, we present a block version of incomplete LU preconditioner which is computed as the by-product of block A-biconjugation process. The pivot entries of this block preconditioner are one by one or two by two blocks. The L and U factors of this block preconditioner are computed separately. The block pivot selection of this preconditioner is inherited from one of the block versions of...
متن کاملA Twisted Block Tangential Filtering Decomposition Preconditioner
For block-tridiagonal linear system of equations, a variant of tangential filtering preconditioners is proposed in this paper. The new variant is based on a twisted block factorization along with certain filtering property. For practical usage, a class of composite preconditioners tested, which are constructed by combining the twisted tangential filtering decomposition preconditioner with the c...
متن کاملA Block Version of the SPAI Preconditioner
We present a block version of the SPAI algorithm and test its performance on large nonsymmetric matrices in a parallel environment. The SPAI algorithm, initially proposed by Grote and Huckle 1], computes a SParse Approximate Inverse for use as a preconditioner for the iterative solution of a sparse linear system of equations. It has proved to be a robust and versatile preconditioner in numerous...
متن کاملA Note on the Block Cipher Camellia
Camellia is a block cipher jointly developed by NTT and Mitsubishi in 2000. In this note, we describe some observations on the design of the cipher.
متن کاملA Note on the Block Sum Transformation
In a recent paper, Bourchard et al. [1] proposed the block sum transformation, a method intended as an alternative to the discrete Fourier transform (DFT), with application to the analysis of excited vibrations of linear systems. In this note, we mention the existence of a number of alternative algorithms for the computation of the DFT, and show that the block sum transformation is equivalent t...
