The European High Performance Computing Joint Undertaking Infrastructure and Access Modes State-of-Play

This paper presents the current state of play of the European High Performance Computing Joint Undertaking (EuroHPC JU) infrastructure with special emphasis on the access mechanisms and the projects that benefit from the allocated HPC resources. The EuroHPC JU procures world-class supercomputing, quantum computing and Artificial Intelligence (AI) Factories infrastructure in order to provide access to users whose research outputs and innovations contribute to societal benefits and industrial competitiveness. In 2025, the procurement of new systems and the launch of additional access calls were undertaken as part of an initiative to support projects using AI technologies in their applications, especially targeting industry, small and medium-sized enterprises (SMEs) and startups. Besides this new initiative, the EuroHPC JU continues to support all types of research coming from academia, industry and public sector with the existing well-established access mechanisms. In this context, an overview of the available and upcoming infrastructure is presented and an analysis of access mechanisms together with the projects accessing the infrastructure is showcased.
