Highlights Keywords High-Performance Computing, Quantum Chromodynamics, Computational Physics, Lattice QCD, Domain Decomposition, Energy, Engineering Technologies used GPU, HPC, LQCD, AMG, LMA Challenge Lattice Quantum Chromodynamics (QCD) calculations are computationally intensive due to their large problem size, requiring high-resolution grids and extensive statistical ensembles. A critical step in these calculations is inverting the Dirac operator to compute quark propagators, essential for studying hadrons. However, this operator is poorly conditioned, particularly for light quark masses, making solvers … Continue reading Success Story: MG4ML
