This webinar will focus on parallel matrix-free multigrid for extreme scale computing.
Multigrid is one of the most efficient algorithms to solve linear systems for elliptic partial differential equations, and matrix-free variants are essential to reach the best possible performance. This will be demonstrated for positive definite systems as they arise in the discretization of the gyrokinetic Poisson equation, as well as indefinite systems that originate in viscous flow problems.
