TL;DR: The overall Trilinos design is presented, describing the use of abstract interfaces and default concrete implementations and how packages can be combined to rapidly develop new algorithms.

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.
Journal ArticleDOI
Block Preconditioners Based on Approximate Commutators
TL;DR: A strategy for automatically generating a block preconditioner for solving the incompressible Navier--Stokes equations is introduced and it is demonstrated that with this strategy the favorable convergence properties of the preconditionsing methodology are retained.
Journal ArticleDOI
A taxonomy and comparison of parallel block multi-level preconditioners for the incompressible Navier-Stokes equations
TL;DR: This taxonomy illuminates the similarities and differences among these preconditioners and the central role played by efficient approximation of certain Schur complement operators and compares them to an additive Schwarz domain decomposition (DD) algorithm.
