A preconditioning technique based on the application of a fixedbut arbitrary number of I + Smax steps is proposed. A reduction of the spectral radius of the Gauss-Seidel iteration matrix is theoretically analyzed fordiagonally dominant Z-matrices. In particular, it is shown that after a finitenumber of steps this matrix reduces to null matrix. To illustrate the performance of the proposed technique numerical experiments on a wide variety ofmatrices are presented. Point and block versions of the preconditioner are numerically studied.Se propone una técnica de precondicionamiento para el método deGauss-Seidel basada en la aplicación de una cantidad de pasos arbitrarios perofijos del precondicionador I + Smax.
