Our solution
Modern data centres are under increasing pressure to improve their energy efficiency, whilst workloads related to AI and data analytics continue to grow and the processing of strategic data using sovereign hardware has become a geopolitical necessity.
SiPearl CPUs offer the compute density and energy efficiency that hyperscalers and sovereign cloud providers need to scale cost-effectively, without compromising on throughput, data residency requirements and security.
Typical workloads
-
AI inference at scale
-
Real-time data analytics
-
Enterprise application hosting
-
Distributed storage platforms
-
Containerised microservices
Why SiPearl
→ A high-throughput architecture optimised for concurrent and mixed workloads in the cloud.
→ Energy efficiency that directly reduces Power Usage Effectiveness and operating costs at scale.
→ A European design ensuring a reliable cloud infrastructure and compliance with data sovereignty requirements.
Our collaborative projects
for sovereign cloud
Working closely with industry leaders, start-ups, universities and research institutes, SiPearl is involved in several European collaborative projects focused on solutions and infrastructure for sovereign cloud computing.
These projects are at the moment Aero, OpenCube, Riser and HIGHER.
AERO, an essential addition to the EPI project
Funded by the European Union, the AERO project complements the efforts of the EPI project by focusing on the development of an open source software ecosystem needed to optimise the efficiency of EPI hardware and facilitate the integration of processors in the cloud. The aim is to promote innovation, facilitate the adoption of these advanced technologies in cloud computing, and strengthen Europe’s competitiveness in this field.
Our partners
Our partners are: Université de Genève, Codeplay, Manchester University, Ubitech, Pierer Innovation, Red Hat, Foundation for Research and Technology – Hellas (FORTH), Virtual Open Systems, Università di Pisa and Sednai.
This project started in January 2023 and is scheduled for completion in June 2026.
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 processors 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.
Our partners
Ours partners are: TUM, KTH – Royal Institute of Technology, Semidynamics, ECMWF and Hewlett Packard Enterprise.
Funded by Horizon Europe programme, the OpenCUBE project launched in January 2023 is scheduled for completion in December 2026.
Riser, first all-European Risc-V cloud server infrastructure
Riser will develop the first all-European Risc-V cloud server infrastructure, significantly enhancing Europe’s open strategic autonomy. Riser will leverage and validate open hardware high-speed interfaces combined with a fully-featured operating system environment and runtime system, enabling the integration of low-power components, including Risc-V processor chips from the EPI and Eupilot projects, in a new energy-efficient cloud architecture.
Our partners
Our partners are: Foundation for Research and Technology – Hellas (FORTH), project coordinator, Barcelona Supercomputing Center, CloudSigma AG, Exapsys, Extoll and Semidynamics.
A Horizon Europe 2027 project
Funded by Horizon Europe 2027, this project started in January 2023 and is scheduled for completion in December 2026.
HIGHER, European Heterogeneous Cloud/Edge Infrastructures for Next Generation Hybrid Services
HIGHER aims to develop and validate European modules, technologies and complete systems for cloud and edge computing, developed on the basis of open standard architectures (OCP), combined with new open-source runtime software stacks, capable of supporting efficient services and applications for cloud and edge computing.
Our partners
The consortium is composed of SiPearl, Foundation for Research and Technology – Hellas (FORTH), Exapsys, Semidynamics, Barcelona Supercomputing Center, CloudSigma AG, Rise Research Institute of Sweden (Rise), KTH, Institute of Communication and Computer Systems (ICCS) and 2CRSI.
This collaborative project is funded by Horizon Europe. It will last 36 months and is scheduled for completion in December 2027.
