Course Description: 
 
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.
