EXDCI is an EU-funded CSA project, in which PRACE and ETP4HPC have worked towards the development of a common European HPC Strategy by getting the ecosystem stakeholders to share their perspectives on positioning Europe on the Exascale roadmap. Achievements of the project include the preparation of the Strategic Research Agenda (SRA), the Scientific Case for HPC, maintaining international cooperation via BDEC workshops, the coordination of training and job offerings via a web portal, the identification of relevant KPI for the HPC ecosystem, and the organisation of the European HPC Summit Week. An EXDCI-2 proposal is underway to continue these coordination activities in the framework of this very dynamic European HPC ecosystem.
