This project federates efforts from 3 pan-European ESFRI infrastructures (HL-LHC, SKAO and SLICES-RI) in physical sciences, Big Data, and in the computing continuum supporting flagship instruments that will maintain and strengthen European leadership in high-energy physics and astronomy. The main goal is to enable key science projects, with the search for Dark Matter serving as a pilot program, combining the complementary capabilities of these three unique research infrastructures.

ODISSEE will deliver evolutionary and revolutionary hardware and software platforms to address the corresponding digital challenges in a highly competitive international context.

• Developed through a joint and comprehensive R&D program with industry partners, as well as access to cutting edge experimental facilities from SLICES-RI, so as to enable HL-LHC and SKA to process and analyze the vast volumes of raw data they produce.
• Targeting such dataflow driven applications opens the way to a new range of technologies and services, feeding SLICES-RI with a unique yet representative set of specifications to progress their operational & experimental capacities at an unprecedented scale, increasing the dissemination potential.
• Bringing these 3 infrastructures to their full capacity, as well as operating and maintaining them, pose similar grand challenges across the digital continuum and require addressing the 3 dimensions of sustainability.

Co-design and close partnership of academia with European companies will foster competitiveness of European industry and promote digital sovereignty.

The project is deeply embedded into both regional and international R&I ecosystems, with strong connections to several major European initiatives and associated partnerships with main technology providers. Strong and lasting impact is built-in the two-fold exploitation strategy including the development of unique in-depth training for R.I. staff and extensive trans-sectoral dissemination.
