TL;DR: This study considers multiphysics applications from algorithmic and architectural perspectives, where “algorithmic” includes both mathematical analysis and computational complexity, and “architectural’ includes both software and hardware environments.

TL;DR: In this article, the authors present a practical computer implementation of a technique which dramatically speeds up the convergence of the infinite series Green's function associated with the Helmholtz operator in the case of periodic structures.

TL;DR: In this paper, a finite difference for elastic waves is introduced and the model is based on the first order system of equations for the velocities and stresses of the elastic wave and is tested on a series of examples including the Lamb problem, scattering from plane interf aces and scattering from a fluid-elastic interface.

TL;DR: This paper considers algebraic multigrid (AMG), a popular and highly efficient iterative solver for large sparse linear systems that is used in many applications, and presents a performance model for an AMG solve cycle and performance measurements on several massively-parallel platforms.

TL;DR: These protocols address challenges in equilibrating and sampling when kinetics can be very different with changes in surfactant concentration, and with minor changes in molecular size and structure, even using the same force field parameters.
