"Domain Decomposition in the Mainstream of Computational Science"

David E. Keyes

Richard F. Barry Professor of Mathematics & Statistics,
Old Dominion University

Abstract:
Over the past two decades, domain decomposition has grown from an elegant 
mathematical technique to the dominant paradigm of large-scale scientific 
simulation for systems governed by partial differential equations.  Two 
major families of domain decomposition methods -- Newton-Krylov-Schwarz and 
FETI-DP -- have been scalably employed on the ASCI platforms of the U.S. 
Department of Energy for mechanics problems, up to several thousand 
processors.

One of the many scientific software projects intent on "packaging" the
fruits of research in domain decomposition methods for mainstream
computational scientists is a five-year, nine-institution "Terascale
Optimal PDE Simulations Integrated Software Infrastructure Center", a
component of DOE's new Scientific Discovery through Advanced Computing 
(SciDAC) initiative.  The speaker, who serves as the TOPS project lead, 
will review the current algorithmic state of the art, outline the 
philosophy and goals of the center, and highlight some of the research 
challenges ahead, in algorithms and in software.
