Resly Suidgeest - Recycling Techniques for Induced Dimension Reduction Methods Used for Solving Large Sparse Non-Symmetric Systems of Linear Equations
Abstract:

Induced Dimension Reduction (IDR) methods are among the most stable and efficient iterative methods for solving large, sparse, non-symmetric systems of linear equations known today. When sequentially solving multiple linear systems with equal coefficient matrices, the recycling of quantities from one run of an IDR algorithm for use with the next system turns out to sometimes outperform even an 'optimal' Krylov subspace method per matrix-vector multiplication used.

In this talk we will first see the theoretical basis of an IDR algorithm. Next, we will delve into the recycling techniques that I have studied for my thesis. After motivating the use of the techniques by some impressive convergence results, we will investigate some disadvantages and how one might counter them, prior to trying to justify the performance, on which little is known for IDR methods in general.
