• We compare the hyperplane and 16-color vectorizations of minimal residual and conjugate residual methods with an incomplete LU preconditioning to solve the lattice Dirac equation in the Wilson formulation. The performance was assessed in terms of the Euclidean distance from the true solution for various hopping parameters on a quenched gauge configuration at fl= 5.5 on an 84 1attice. The 16-color vectorization requires 2 - 4 times more iterations than the hyperplane vectorization. Even with the best choice of the acceleration parameter, the latter method is preferable to the former unless the computing time for one iteration of the latter differs with that of the former by a factor of two or more.
