AbstractLattice Quantum ChromoDynamics (QCD) is one of the scientific fields which require most large-scale numerical simulations. QCD is the fundamental theory of the strong interaction among quarks and gluons inside hadrons. Because of difficulty in analytic calculations, numerical simulations of lattice QCD are important to explore the properties of hadrons and determine their matrix elements. In this report, we explain fundamental aspects and algorithms of lattice QCD, and how its large-scale simulation is performed on massively parallel computers with an example at KEK (High Energy Accelerator Research Organization). JLQCD (Japan Lattice Quantum ChromoDynamics) Collaboration is performing dynamical simulations with overlap fermions, which have theoretically elegant features while require high numerical cost. We also introduce international and domestic activities, ILDG (International Lattice Data Grid) and JLDG (Japan Lattice Data Grid) respectively, to share the configuration data produced in lattice QCD simulations.
