Progress in algorithms and numerical tools for QCD

May 15, 2017, 2:00 PM → May 16, 2017, 6:00 PM Europe/Zurich

Orsay, France

Organized in the framework of the GDR "QCD", this workshop aims to discuss about progress in algorithms and numerical methods used by theorists and experimentalists in their research activities devoted to the different topics covered by the GDR. Links between those progresses and new computer architectures of the exa-scale era will be outlined.
