European projects

SiPearl est partenaire d'EPI

EPI Phase 2, a more powerful and efficient microprocessor


Launched by the Euro-HPC Joint Undertaking in January 2022, the European Processor Initiative Phase 2 aims to:

  • strengthen the competitiveness and leadership of European industry and science;
  • develop European microprocessor technology with drastically better performance and power ratios;
  • tackle important segments of broader and/or emerging HPC and big-data markets.

In particular, it will move forward with the development of the European microprocessor targeting future European exascale supercomputers by applying technological enhancements to the baseline of Rhea. With its partners, SiPearl will increase the number of cores and memory bandwidth, and also add chip acceleration and custom IP blocks.

In parallel, the partners focus on the development of an open common platform standard aiming to efficiently interface microprocessors and accelerators in-package, implementing cache coherency, and validating the toolchains and runtime between microprocessors and accelerators.

SiPearl est partenaire d'OpenCube

OpenCUBE, a cloud computing solution to be deployed on European infrastructure


This project proposes to design OpenCUBE, a full-stack solution of a validated European Cloud computing blueprint to be deployed on European hardware infrastructure. OpenCUBE will develop a custom cloud installation with the guarantee that an entirely European solution like SiPearl microprocessors and Semidynamics RISC-V accelerators can be deployed reproducibly. It will provide a solid basis for the European cloud services, research, and commercial deployments envisioned to be core for federated digital services via Gaia-X. To remain competitive for the European Green Deal, OpenCUBE is designed to make energy awareness a core feature at all levels of the stack.
