TL;DR: The Trilinos Project is an effort to develop parallel solver algorithms and libraries within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific applications.
Journal ArticleDOI
Parallel multigrid smoothing: polynomial versus Gauss--Seidel
TL;DR: It is shown that, although parallel computers are the main motivation, polynomial smoothers are often surprisingly competitive with Gauss-Seidel smoothers on serial machines.
ML 5.0 Smoothed Aggregation User's Guide
TL;DR: In this paper, the authors describe a specic algebraic multigrid approach, smoothed aggregation, for solving linear systems of equations, which can be used as a stand-alone package or to generate preconditioners for a traditional iterative solver package (e.g. Krylov methods).
Journal Article
Cache Optimization for Structured and Unstructured Grid Multigrid
TL;DR: In this paper, suitable blocking strategies for both structured and unstructured grids will be introduced to improve the cache usage without changing the underlying algorithm.
