NIC: John von Neumann-Institute for computing Research group “ Elementary Particle Physics” Guidelines for presentations’ format Cooperation between Hemholtz Centres Forschungszentrum Jülich, Deutsches Eletronensynchroton DESY and GSI Helmholtzzentrum für Schwerionenforschung NIC maintains five research groups: Computational Biophysical Chemistry (JSC), Computational Structural Biology (JSC), Elementary Particle Physics (DESY), Lattice Quantum Chromodynamics (GSI), Nuclear Matter (GSI) NIC provides supercomputer time at Jülich supercomputer centre through a peer review process Gauss, Prace etc. ? Mention management of configuration generation, collaborations guidance Link to universities European Joint Doctorates Lattice Field Theory | Karl Jansen | Theory | MU

NIC Research highlight: computation of running strong coupling constant Have one-two slides for running coupling, PRL One graph, precise determination with controlled errors Lattice Field Theory | Karl Jansen | Particle Theory | MU

Further achievements Selected achievements (only mention, not discuss in detail) NIC project excellence award muon anomalous magnetic moment Development of multilevel algorithm, breakthrough Spin and Momentum composition of nucleon, PRL Development of NPHQET for B-decays (Belle II) Scalar quark content of nucleon  coupling to WIMP, PRL Tensor networks, PRL and PRX Non-perturbative renormalization of lattice PDFs ? Lattice Field Theory | Karl Jansen | Particle Theory | MU

Outlook One slide outlook Continuum limit for four active quarks in physical condition Tensor networks in higher dimensions Half the error of alpha_s Investigate reliability of perturbation theory Form factors for Belle II Further development of speed up if simulations (e.g. domain decomposition) Activities related to scientific computing/data (c.f. CDCS) Be ready for the unkwown Lattice Field Theory | Karl Jansen | Particle Theory | MU
