Preconditioning by several incomplete Cholesky decompositions is discussed. A variant is discussed that is appropriate for a nine-point stencil and parallel computing. The coefficients of the preconditioning matrix are explicitly given. Numerical results are presented for examples with up to 512 grid points.
