European Open-Source Cloud Infrastructure for High-Performance Computing and Energy Efficiency

digitalTestedTRL 5

Imagine building a computer system where every part, from the brain chips to the management software, is made in Europe and open for anyone to inspect. It is like creating a standardized blueprint for a digital warehouse that runs on very little power. This allows companies to run massive calculations without relying on foreign technology providers.

The business problem

What needed solving

European companies rely on foreign cloud hardware and software, creating risks for data sovereignty and energy inefficiency. There is a lack of a validated, open-source full-stack blueprint for European-made processors.

The solution

What was built

A pre-production reference implementation of a software stack and a prototype hardware platform deployed in a data center. This includes OS, resource management, and middleware for RISC-V accelerators.

Who can put this to work

Meteorology & Climate Science
enterprise
Target: Weather forecasting agency

If you are a forecasting agency dealing with massive Digital Twin workflows — this project developed a full software stack that enables high-performance computing on European processors. This ensures data sovereignty and energy-aware processing for complex climate models.

Cloud Infrastructure
mid-size
Target: European Cloud Service Provider (CSP)

If you are a CSP dealing with dependence on non-EU hardware — this project developed a validated blueprint for cloud services using SiPearl and Semidynamics RISC-V components. This allows you to deploy reproducible, open-source cloud environments that align with Gaia-X standards.

Energy Management
enterprise
Target: Data center operator

If you are an operator dealing with high electricity costs and carbon footprints — this project developed a stack that makes energy awareness a core feature. It exposes APIs from the hardware level up to the electricity grid to optimize power usage.

Frequently asked

Quick answers

What is the cost or pricing for using this technology?

Based on available project data, no commercial pricing is listed as the project focuses on an open-source reference implementation funded by a EUR 4,259,360 EU contribution.

Can this be scaled to an industrial level?

Yes, the project is designing a blueprint for cloud services intended for commercial deployments and federated digital services via Gaia-X.

What are the IP and licensing terms?

The project is built on industry-standard open APIs using Open Source components to ensure the solution can be deployed reproducibly.

How does this integrate with existing hardware?

It is specifically designed to integrate with European processors like SiPearl Rhea and Semidynamics RISC-V accelerators.

What is the timeline for availability?

The project period runs from 2023-01-01 to 2026-12-31, with a pre-production reference implementation as the goal.

Consortium

Who built it

The consortium is heavily industry-weighted with a 57% industry ratio, comprising 4 industrial partners (including 3 SMEs) and 3 academic/research entities. This balance suggests a strong push toward commercial viability, with the technical lead held by KTH (Sweden) and deployment already occurring at the HPE Grenoble Data Center.
