Successive overrelaxation, multigrid, and preconditioned conjugate gradients algorithms for solving a diffusion problem on a vector computer
Journal Article

· Appl. Math. Comput.; (United States)
The authors discuss the treatment of three numerical algorithms: successive overrelaxation, multigrid and conjugate gradients preconditioned by a fast poisson solver for solving large but mildly behaved diffusion problems on a vector computer with memory-to-memory architecture. The problem is a symmetric nonnegative definite matrix equation arising from a cell-centered finite difference approximation of a 3-d diffusion equation with full Neumann boundary conditions. 9 references.
