• Strengthening the European HPC ecosystem by enabling European stakeholders to enhance HPC applications and codes in academic and industrial cases of interest for Europe and Japan in the identified priority domains.
• Improved sharing of information and expertise to solve common societal problems with the use of advanced computing.
• Facilitating the exchange of researchers and engineers between Japan and the EU and their access to advanced Japanese and EuroHPC JU supercomputing resources.
• Improved international cooperation of EU-Japan HPC communities on advanced HPC application development, with a roadmap for future collaboration in targeted areas.

Support the implementation of the Japan-EU Digital Partnership in order to strengthen cooperation with Japan, addressing the priority domains of the HPC collaboration identified in the Partnership.

Proposals should address all the identified priority domains, with activities in HPC applications such as co-development of applications in biomedical, material science, seismic/tsunami and/or weather and climate modelling, performance measuring, test and optimisation for different architectures; promoting the exchange of researchers and engineers between Japan and the EU, and elaborating a roadmap for future actions to enhance cooperation.

Proposals should clearly demonstrate a clear link with the existing European HPC Centres of Excellence supported in the identified priority domains.

Proposals should describe the facilitation of reciprocal access for European and Japanese researchers to advanced Japanese and EuroHPC JU supercomputing resources (notably the utilisation of the “Fugaku” and EU/EuroHPC’s LUMI, Leonardo and MareNostrum 5 supercomputers), in conformity with the respective supercomputers’ access policy. It is expected that the EuroHPC JU and Japanese HPC entities will provide dedicated computing time in their respective infrastructure to run HPC applications of European and Japanese users in the frame of this action.

Japanese partners will not be funded by the EU and they are expected to participate in the project with their own funding.
