Abstract:
A Scalable compact Localized Exponential Time Difference method is proposed for the solution of the phase field equations. The method combines decompositions of compact spatial difference operators on a regular mesh with stable and accurate exponential time integrators and efficient algorithms. It can deal with stiff nonlinearity and both homogeneous and inhomogeneous boundary conditions of different types. We also present techniques for implementation on various modern heterogeneous hardware platforms, including clusters equipped with Intel Xeon and Xeon Phi processors and the Sunway TaihuLight supercomputer. In the application end, the highly nonlinear and severely stiff Cahn-Hilliard equations with degenerate mobility for microstructure evolution are solved at extreme scale, demonstrating that the latest advent of high performance computing platform and the new advances in algorithm design are now offering us the possibility to simulate the coarsening dynamics accurately at unprecedented spatial and time scales.
