Abstract
This paper described the halfsweeps multigrid method with the rotated high-order discretization for solving the two dimensional Poisson equation with Dirichlet boundary conditions. This method along with several ordering strategies shows a relatively good in accuracy and drastic improvement in execution time. The numerical results of the test porblem are given.
