Description
The Joint ECFA-NuPECC-APPEC (JENA) Activities launched an initiative (JENA Computing) in 2023 to promote the increasing need for discussions on the strategy and implementation of European federated computing at future large-scale research facilities. In workshops and dedicated working groups on specific topics, expert groups from all relevant research areas were formed to compile an overview of existing strategies in the individual countries and communities. Here we present a summary of the resulting Working Group Reports, including the most important recommendations from these areas of computing. Furthermore, an additional chapter on sustainability in the field of computing is included. This version of the JENA White Paper on European Federated Computing serves as input to the European Strategy for Particle Physics 2026 update (ESPPU).
