European Projects

Participation in major European Projects of the High Performance Computing and Artificial Intelligence worlds forms a fundamental part of our strategy. These projects bring valuable human resources and expertise, and give us access to a network of important national and international institutions and companies, with which we can co-design and co-develop highly innovative solutions to be later replicated on the market.
The main entity financing and sustaining a large part of these projects is the European High Performance Computing Joint Undertaking (EuroHPC JU), headquartered in Luxemburg. EuroHPC JU coordinates the efforts and manages the resources of various European Countries with the aim of making Europe the world leader in Supercomputing.
E4 is currently involved with 15 projects supported by the EuroHPC JU.
The main objective of the ADMIRE project is to establish a control mechanism by creating an active I/O stack that dynamically adjusts computation and storage requirements through intelligent global coordination, malleability of computation and I/O, and scheduling of storage resources along all levels of the storage hierarchy. To achieve this, the project will develop a software-defined framework based on the principles of scalable monitoring and control, separated control and data paths, and the orchestration of key system components and applications through embedded control points.
E4’s role is to develop Software Heritage (SH) applications and tests, distribute and profile SH, and provide ADMIRE’s partners with access to the ARMIDA Cluster.
Random Power exploits the quantum properties of semiconductors to generate a virtually endless stream of random bits feeding cyber-security systems. In ATTRACT phase 1, the consortium, formed of two research centres and two companies, designed, produced, commissioned, and fully qualified a small form factor card with an embedded bit generator. Now, the consortium includes RaP!, a spin-off of original partners, and has been expanded to integrate teams with complimentary knowledge and expertise from other ATTRACT projects and beyond, with the aim of developing a True Random Bit Generator platform.
E4’s role is to develop and implement a Randomness Farm, based on hardware that incorporates multiple generators into the infrastructure, with a scalable architecture. The hardware is complemented with customized software development to guarantee safe transmission of the bitstream, advanced functionality in real time and a suite of services to maximise the adoption of the technology.
The project will develop an open and portable cloud management framework for automatic and adaptive optimization of applications by mapping jobs to the most suitable resources in a heterogeneous system landscape. By utilizing holistic monitoring, DECICE aims to construct a digital twin of the system that reflects on the original system. An AI-scheduler makes decisions on placement of job and data as well as conducting job rescheduling to adjust to system changes. A virtual training environment is provided that generates test data for training of ML-models and the exploration of what-if scenarios. The portable framework is integrated into the Kubernetes ecosystem and validated using relevant use cases on real-world heterogeneous systems.
E4’s role is to integrate testing task and lead the Work Package on deployment, validation and performance assessment.
DYNAMOS develops fast (1 ns) and widely tunable (>110 nm) lasers, energy-efficient (~ fJ/bit), broadband (100 GHz) electro-optic modulators, and high-speed (1 ns) broadcast-and-select packet switches as photonic integrated circuits (PICs). DYNAMOS meets the expected outcome objectives and call scope by proposing the development of low energy (few pJ/bit) PICs, which are integrated into modular and scalable subsystems, and subsequently utilized to demonstrate novel data centre networks with highly deterministic sub-microsecond latency to enable maximum congestion reduction, full bisection bandwidth (lower congestion) and guaranteed quality of service while reducing cost per Gbps.
The proposed network offers optical circuit switched reconfiguration and guaranteed (contentionless) full-bisection bandwidth, allowing any computational node to communicate to any other node at full-capacity. DYNAMOS co-develops the entire ecosystem of transceivers, switches and networks to boost overall performance and to reducing the total cost of data exchange, instead of focusing on the improvement of individual optical links or interfaces.
E4 is the “Network & system demonstrations” work leader. E4 will formalize the set of integration and demonstration activities in order to systematically showcase the ability of the devices, network architecture and control, technologies to deliver the goals of system-network scalability, network related energy efficiency, network latency, network throughout, distributed compute task performance. E4 will aim to combine the compute motherboards with the DYNAMOS interface card and optical switch.
The European Processor Initiative (EPI) is a cornerstone of the European initiative towards strategic autonomy in HPC, chip technologies and infrastructure.
