BoomerAMG: a parallel algebraic multigrid solver and preconditioner
TL;DR: This paper describes an implementation of a parallel AMG code, using the algorithm of A.J. Cleary, and considers three basic coarsening schemes and certain modifications to the basic schemes, designed to address specific performance issues.
Journal ArticleDOI
Algebraic Multigrid Based on Element Interpolation (AMGe)
Marian Brezina,A. Cleary,Robert D. Falgout,Van Emden Henson,Jim E. Jones,Thomas A. Manteuffel,Stephen F. McCormick,J. Ruge +7 more
TL;DR: This work develops a theoretical foundation for AMGe, an algebraic multigrid method for solving the discrete equations that arise in Ritz-type finite element methods for partial differential equations and presents numerical results that demonstrate the efficacy of the method.
Journal ArticleDOI
Robustness and Scalability of Algebraic Multigrid
A. Cleary,Robert D. Falgout,Van Emden Henson,Jim E. Jones,Thomas A. Manteuffel,Stephen F. McCormick,Gerald N. Miranda,John W. Ruge +7 more
TL;DR: Some of the situations in which standard AMG does not work well are shown and the current directions taken by AMG researchers to alleviate these difficulties are indicated.
