| Abstract |
The Fourteenth Copper Mountain Conference on Iterative Methods was held March 20--25, 2016, in Copper Mountain, Colorado. The meeting featured more than 170 presentations covering a broad spectrum of topics in scientific computing. Highlighted topics for the 2016 conference included iterative linear algebraic techniques in data mining, optimization, inverse problems, nonlinear solvers, methods for large-scale eigenvalue and singular value computations, implementation of iterative solvers on emerging architectures, uncertainty quantification, robust and scalable iterative solution of coupled multi-physics problems, model reduction, and methods based on low-rank approximations. Besides data mining, applications to energy, climate, imaging, fluids and electromagnetics were especially encouraged. Several speakers addressed discretization techniques for partial differential equations from the point of view of their impact on the design and performance of iterative solvers. As is customary for Copper Mountain, graduate students accounted for a significant portion of the attendees. A cherished aspect of the Copper Mountain Conference is the traditional Student Paper Award Competition. The Student Paper Award Committee had the challenging task to select the best among a high number of strong submissions. In the end, four papers were selected for the award. As usual, a plenary session was exclusively devoted to the presentations by the four student winners: Sarah Gaaf from the University of Eindhoven in the Netherlands, Kookjin Lee from the University of Maryland at College Park, Johann Rudi from the University of Texas at Austin, and Alessio Spantini from the Massachusetts Institute of Technology. All four speakers gave engaging and impressive presentations. This was the only plenary session of the conference, all other presentations being held in parallel sessions. This was done in order to give all conference participants the possibility to enjoy the winning student presentations. Michele Benzi (Emory University) and Ray Tuminaro (Sandia National Laboratories) served as conference co-chairs, while Sven Leyffer chaired the Student Paper Award Committee. Management services were provided by Annette Anthony of Front Range Scientific Computations, Inc. The Conference gratefully acknowledges financial support from the US Department of Energy, the US National Science Foundation, IBM, Argonne National Laboratory, Lawrence Livermore National Laboratory, Los Alamos National Laboratory, Sandia National Laboratories, and Emory University. The Copper Mountain Conference is organized in cooperation with the Society for Industrial and Applied Mathematics (SIAM). As is customary, submissions to this special section were open to the scientific community, as advertised in advance on the web sites of the SIAM Journal on Scientific Computing (SISC) and the Copper Mountain Conference. The 40 papers in this section cover a wide range of topics covering iterative methods for linear and nonlinear problems, eigensolvers, randomized algorithms, iterative techniques for optimization and inverse problems, multilevel solvers for graph Laplacian systems, and a variety of applications including fluid flow, electromagnetics, and power system modeling. High-performance computing and software aspects are also covered. Collectively, these papers provide an impressive testimony of the continually evolving and growing field of iterative methods. The guest editorial board worked very hard to ensure a rigorous peer-review process while meeting deadlines. We owe special thanks to Brittni Holland (SIAM Editorial Associate) and Mitch Chernoff (SIAM Publications Manager) for their efforts on this special section. |
