摘要: In this talk, we first introduce some time parallel algorithms. Then we present an implicit two-level space-time additive Schwarz algorithm for solving parabolic equation. With this method, the parabolic equation is solved in parallel on both space and time directions. We develop a convergence theory and show how the convergence rate depends on the mesh sizes, the number of subdoamins and the window size.Some numerical experiments carried out on a parallel computer with thousands of processors con_rm the theory in terms of the number of iterations, as well as the strong and weak scalabilities.
