Abstract

In this talk, the speakers will give an overview of the numerical methods used in Lattice Quantum Chromodynamics for the study of properties of quarks and gluons inside nuclei. The speakers will focus on the approaches used for solving linear systems of massive dimensions that arise from the discretization of the Dirac operator. These are namely iterative Krylov-subspace solvers preconditioned by algebraic multigrid methods, which are state-of-the-art in the field. After introducing them, the speakers will present the developments that they have carried out under the PRACE project LyNCs in collaboration with Inria and LRZ.
