Instructor

Edmond Chow Georgia Institute of Technology, USA http://www.cc.gatech.edu/~echow/Edmond Chow is an Associate Professor in the School of Computational Science and Engineering at Georgia Institute of Technology, USA. He previously held positions at D. E. Shaw Research and Lawrence Livermore National Laboratory. His research is in developing and applying numerical methods and high-performance computing to solve large-scale scientific computing problems and seeks to enable scientists and engineers to solve larger problems more efficiently using physical simulation. Specific interests include numerical linear algebra (preconditioning, multilevel methods, sparse matrix computations) and parallel methods for quantum chemistry, molecular dynamics, and Brownian/Stokesian dynamics. Dr. Chow earned an Honors B.A.Sc. in Systems Design Engineering from the University of Waterloo, Canada, in 1993, and a Ph.D. in Computer Science with a minor in Aerospace Engineering from the University of Minnesota in 1997. Dr. Chow was awarded the 2009 ACM Gordon Bell Prize and the 2002 U.S. Presidential Early Career Award for Scientists and Engineers (PECASE).

Course Overview

The mathematical development of modern numerical methods is intimately tied to high-performance computing, particularly for large-scale problems. This short course presents current ideas on high-performance numerical solvers, as well as foundational concepts necessary to understand the newest methods. The focus will be on numerical linear algebra and parallel computing techniques. Under consideration are parallel iterative solvers that avoid costly communication synchronization, hierarchical matrix representations for kernel-based problems and their relation to fast solvers, multigrid methods for solving extremely large problems in a scalable fashion, and other recent developments. This short course complements and extends the topics presented in the High-Performance Numerical Solvers short course taught in Summer 2016 (https://sites.google.com/site/school4scicomp/previous/2016-b-spring).
