Résumé :
In this talk we discuss a highly parallel preconditioner for solving large sparse linear systems of equations. The preconditioner is based on nested dissection ordering and uses filtering techniques to alleviate the effect of low frequency modes on the convergence of the iterative method. We also discuss overlapping techniques to further increase the numerical efficiency of the preconditioner.
