Abstract
Let Ax = b be a linear system where A is a symmetric positive definite matrix. Preconditioners for the conjugate gradient method based on mu ltisplittings obtained by incomplete Choleski factorizations of A are studied. The validity of these preconditioners when A is an M-matrix i s proved and a parallel implementation is presented.
