Progress in algorithms and numerical tools for QCD

9 juin 2026, 13:50 → 10 juin 2026, 19:00 Europe/Zurich

IJCLab (Orsay, France)

Organized in the framework of the GDR "QCD", this workshop aims to discuss about progress in algorithms and numerical methods that theorists and experimentalists use in research activities covered by the GDR. The role of new computer architectures of the exa-scale era will be emphasized.
