ODISSEE, solutions for processing massive flood of scientific data on the fly using AI and frugal, flexible algorithms
Flagship physical science infrastructures, such as CERN’s HL-LHC et the SKA Observatory (SKAO) generate massive quantities of raw data (1018 bytes). However, while this flood of data paves the way for major scientific breakthroughs, it also poses a crucial challenge: as current digital technologies are unable to process it, major discoveries could go unnoticed.
The objective of ODISSEE is to meet the needs of the HL-LHC scientific communities at CERN and SKAO by processing data on the fly using AI and frugal, flexible algorithms. To demonstrate the effectiveness of these new technologies, ODISSEE will work on specifiying a pilot combining the use of both SKAO and HL-LHC: the search for the nature of dark matter.

EPI Phase 2,
a more powerful and efficient processor
Launched by the Euro-HPC Joint Undertaking in January 2022, the European Processor Initiative Phase 2 aimed to:
- strengthen the competitiveness and leadership of European industry and science;
- develop European processor technology with drastically better performance and power ratios;
- tackle important segments of broader and/or emerging HPC and big-data markets.
In particular, it moved forward with the development of the European processor targeting future European exascale supercomputers by applying technological enhancements to the baseline of Rhea. With its partners, SiPearl increased the number of cores and memory bandwidth.
In parallel, the partners focused on the development of an open common platform standard aiming to efficiently interface processors and accelerators in-package, implementing cache coherency, and validating the toolchains and runtime between processors and accelerators.
