A parallel multilevel domain decomposition method for ... - In this paper we develop a parallel multilevel domain decomposition method for large-scale source identification problems governed by elliptic equations. A popular approach is to formulate the inverse problem as a PDE-constrained optimization problem. The minima satisfies a Karush-Kuhn-Tucker (KKT) system consisting of the state, adjoint and source equations which is rather difficult to solve on parallel computers. We propose and study a parallel method that decomposes the optimization ...

Domain decomposition and multilevel methods analysis for ... - Domain decomposition methods have proven to satisfy these requirements at least for suitably well-behaved problems. In particular, multilevel methods are the state-of-the-art technique for solving linear equation systems resulting from the discretization of partial differential equations with a cost scaling linearly. In this seminar we aim to an introduction to these methods and their implementation. We focus on their asymptotic analysis through an abstract framework with ...

Additive Schwarz method - Wikipedia - Domain decomposition. Which brings us to domain decomposition methods. If we split the domain [0,1] × [0,1] into two subdomains [0,0.5] × [0,1] and [0.5,1] × [0,1], each has only half of the sample points. So we can try to solve a version of our model problem on each subdomain, but this time each subdomain has only 32 sample points. Finally, given the solutions on each subdomain, we can attempt to reconcile them to obtain a solution of the original problem on [0,1] × [0,1].

PDF Domain Decomposition - - Domain decomposition is an idea that is already useful on serial computers, but it takes on a greater importance when one considers a parallel machine with, say, a handful of very powerful processors. In this context, domain decomposition is a parallel divide-and-conquer approach to solving the PDE.
