DescriptionInsightful, finely resolved simulations of physical models such as Earth-mantle convection
require the solution of systems of equations of enormous size.
A global resolution of the Earth-mantle of about 1km results in more than a trillion (10^{12}) unknowns.
Only solvers with optimal complexity - such as multigrid methods - can achieve that scalability.
In this talk we present the HPC framework HyTeG that implements parallel and matrix-free
finite-element multigrid solvers for extreme-scale simulations as they are required for modern geophysical applications.
We combine excellent performance, scalability and geometric flexibility through structured refinement of unstructured meshes and fully distributed domain partitioning.
