Progress in algorithms and numerical tools for QCD

7 juin 2022, 14:00 → 8 juin 2022, 13:00 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.

Confirmed speakers:    

• Dimitrios Bachtis (University of Swansea)  
• Valerio Bertone (CEA/Irfu)  
• Matteo Bugli (CEA/DAP)
• Eric Dumonteil (CEA/Irfu)    
• Carlo Flore (IJCLab)  
• Samuel Friot (IJCLab)  
• Patrick Fritzsch (Trinity College Dublin)
• Jose Manuel Morgado (University of Huelva)  
• Stéphane Munier (CPhT)    
• Jérémie Quarroz (KIT Karlsruhe)
• Malin Sjödahl (University of Lund)
