Paralel Algirthm for the Solution of High rder Discretization of Elliptic PDEs

摘要

We present a paralel preconditioned-GMRES algorithm for solving second-order elliptic PDEs defined on rectangular domains with Dirichlet and Neumann boundary conditions, and discretized with piecewise Hermite bicubics. The parallel performance of the agoirthm is assessed by way of numerical experiments.
