Europe and Japan Partner to Advance Supercomputing Boundaries

• Europe and Japan have launched the HANAMI collaboration to advance high-performance computing (HPC) research, aiming to create a technological ecosystem independent of dominant global powers.
• The partnership focuses on improving the reproducibility and reliability of scientific simulations across different hardware architectures.
• Strategic goals include advancing "AI for Science" to accelerate research in climate forecasting, medicine, and materials science.

Strategic Cooperation

• The three-year HANAMI project involves European and Japanese researchers sharing expertise to tackle complex computational challenges.
• Europe is actively strengthening its technological sovereignty through the European High-Performance Computing Joint Undertaking, which includes the exascale JUPITER supercomputer in Germany.
• In late 2025, Japan became associated with the Horizon Europe research program, further cementing scientific and technological ties.

Scientific Reliability and AI

• A core challenge is ensuring that simulations remain consistent and accurate when run on diverse, specialized supercomputing architectures.
• Researchers are currently testing methods to enhance the transparency and reproducibility of scientific results.
• Practical applications include high-precision medical simulations, such as modeling nasal airflow to assist in surgical preparation.

Future Outlook

• As AI increasingly drives research, both regions aim to integrate AI into scientific workflows to identify patterns in massive datasets.
• HANAMI partners view collaboration as essential for building long-term resilience, particularly in securing access to advanced computing chips and software ecosystems.
