Domain Decomposition Methods with Adaptive Multipreconditioning

The department of Mathematics and Statistics at the University of Limerick invites you to a seminar by Dr Nicole Spillane (École Polytechnique):

Title: Domain Decomposition Methods with Adaptive Multipreconditioning

Abstract: Domain Decomposition Methods with Adaptive Multipreconditioning Domain decomposition methods are a family of solvers for the parallel resolution of very large linear systems. They all share the idea of approximating the inverse of some matrix by a sum of local inverses (in the so-called subdomains). I will present some classical domain decomposition methods, their limitations and some recent efforts to improve their robustness and scalability so that they can be applied to problems arising from real life simulations. More precisely, I will present two methods: spectral coarse spaces and adaptive multi- preconditioning.

This seminar will take place on Friday 20th April, at 4p.m. in Room A2-002
