We describe the implementation of an iterative method with the goal of gaining a long vector length. The strategy for vectorization by means of multipoint stencils used for discretization of the partial differential equations is discussed. Numerical experiments show that the strategy that requires certain restrictions on the number of grid points in the x and y directions improves the performance on the vector supercomputer.
