N2 - This paper presents a new preconditioning technique for shifted linear systems of equations. It is based on GMRES method with an approximate inverse preconditioner which is developed in a parallel implementation of Sherman-Morrison formula. Numerical examples show that this technique gives an effective scheme than the other procedures, at a low cost of computation.
