HPC Europa is a multinational research access and support programme that provided transnational access to supercomputing resources, technical expertise, and training for academic and industrial researchers across European Union member states and associated countries. Its activities connected high-performance computing centres, university departments, national laboratories, and pan-European initiatives to accelerate computational science, numerical simulation, and data-intensive research. The programme sought to lower barriers to advanced computing for investigators in fields ranging from climate science to materials modelling.
HPC Europa linked major facilities such as PRACE (Partnership for Advanced Computing in Europe), CERN, École Polytechnique Fédérale de Lausanne, Max Planck Society, and CNRS laboratories with users from institutions including University of Cambridge, ETH Zurich, Imperial College London, University of Oxford, and University of Milan. The initiative offered access to machines hosted by centres like Jülich Research Centre, CSCS, BSC Barcelona, FZJ, and CEA. It combined user support from teams affiliated with Technical University of Denmark, KTH Royal Institute of Technology, University College London, and Trinity College Dublin. Collaborations often involved projects tied to programmes such as Horizon 2020, Framework Programme 7, and collaborations with European Research Council grant holders.
Launched in the early 2000s, the programme evolved through a sequence of funded phases aligned with Framework Programme 7 and later Horizon 2020 calls, benefiting from coordination with infrastructures like PRACE and networks including GÉANT. Founding partners included centers associated with High Performance Computing Center Stuttgart, EPCC, SURFsara, and ULAM. Successive iterations expanded machine diversity from vector processors to massively parallel clusters and GPU-accelerated systems from vendors such as IBM, Cray, Intel, and NVIDIA. The development timeline intersected with milestones achieved by projects such as ENES in climate modelling and Human Brain Project computational components, adapting services to emergent workflows in fields fostered by Marie Skłodowska-Curie Actions fellows.
The programme delivered transnational access, remote support, and on-site visits coordinated through partner nodes including Barcelona Supercomputing Center, Jülich Supercomputing Centre, National Supercomputing Centre (UK), and HLRS. Users could apply for allocations reviewed by panels with experts drawn from European Science Foundation, Academia Europaea, and national research councils like Science Foundation Ireland and Deutsche Forschungsgemeinschaft. Services included performance profiling from specialists with ties to SISSA, parallelisation support from groups at University of Edinburgh, code optimisation with teams at Leiden University, and training workshops involving instructors from EPFL and TU Delft. The programme maintained helpdesks connected to initiatives at PRACE-ICEI and coordinated with certification frameworks promoted by EUDAT and OpenAIRE.
Partner institutions spanned continental networks including SURF, RENATER, GARR, and JANET(UK), and hosted architectures such as Cray XC, IBM Blue Gene, and heterogeneous GPU clusters sited at CSCS and BSC. University participants included University of Manchester, University of Bologna, Politecnico di Milano, Delft University of Technology, and RWTH Aachen University. National laboratories and institutes such as CEA, INFN, Forschungszentrum Jülich, and SISSA contributed specialised staff and instrumentation. Interactions with consortia like EOSC and PRACE expanded access pathways and fostered interoperability with regional infrastructures such as LESC facilities and national e-infrastructures funded by ministries of research across France, Germany, Italy, Spain, and United Kingdom.
The programme enabled research across disciplines represented by projects associated with IPCC modelling groups, EuroHPC pilots, and computational chemistry consortia partnering with Max Planck Institute for Chemical Physics of Solids and University of Groningen. Notable applications included large-scale simulations in climate change driven by groups at Met Office Hadley Centre and ensemble experiments linked to ECMWF workflows; materials science studies involving density functional theory carried out with codes like VASP and Quantum ESPRESSO by teams at University of Cambridge and École Normale Supérieure; and bioinformatics and systems biology computations tied to EMBL-EBI and Wellcome Sanger Institute. Publications produced under the programme appeared in journals such as Nature, Science, and Physical Review Letters, and fed into grant proposals for European Research Council Advanced Grants and Consolidator Grants.
Funding derived from scholarships and grants administered by European Commission directorates and routed through host organisations including BSC, CSC – IT Center for Science, and STFC. Governance mechanisms involved steering committees with representatives from PRACE, national funding agencies such as UK Research and Innovation, ANR (France), DFG (Germany), and advisory boards containing members affiliated with Academia Europaea and European Science Foundation. Allocation committees followed peer-review criteria modelled on procedures used by ERC panels, and compliance obligations aligned with rules from Horizon 2020 and subsequent Horizon Europe frameworks.
Critiques addressed limited allocation sizes for large-scale ensemble campaigns proposed by teams in climate science and astrophysics, difficulties in porting legacy codes developed at institutions like Princeton University and Caltech to accelerator-rich systems from NVIDIA and AMD, and administrative overhead reported by applicants engaging with funding agencies including European Commission units and national research councils. Other challenges included maintaining interoperability with evolving standards from OpenMP and MPI consortia and sustaining long-term support amid transitions to regional infrastructures like EuroHPC centres and national supercomputing investments by governments such as Germany and France.
