To obtain an ecient parallel algorithm to solve sparse linear systems with the preconditioned conjugate gradient (PCG) method, two types of parallel preconditioners are introduced. The ยฎrst is a polynomial preconditioner type based on a multisplitting of the matrix system, and the second one is obta
