The “SC23” conference and exhibition held in Denver, Colorado (November 13th-16th) provided a great opportunity to network with many of our colleagues and collaboration partners from the European HPC ecosystem (including R&D projects and ETP4HPC). Results from our recent and ongoing projects CASTIEL-2, FF4EuroHPC and Inno4scale were presented in the exhibition spaces of our partners and also of the EuroHPC Joint Undertaking. A presentation by Guy Lonsdale during a Birds-of-a-Feather session on industrial use of HPC gave an overview of the recommendations from the market studies performed within the HPC-GIG project.
