Role in the HIGHER Project
Within HIGHER, EXTOLL plays a central role in system architecture and hardware integration, leading the Architecture and Specifications Task.
Its main responsibilities include:
- Architecture and Specifications Leadership
EXTOLL coordinates the definition of specifications for the two Processor Modules, the management module, and the overall DC-MHS server. Working closely with partners including SIPEARL, SMD, EXA, and others, the company ensures that all system components — from DC-SCM to OCP-NIC — are cohesively designed and optimized.
- High-Speed Interconnect Development
Leveraging its deep expertise in interconnect design, EXTOLL contributes to the HIGHER platform development, focusing on the use of high-speed links for seamless interfacing among PCB components and I/O peripherals, ensuring optimal data transfer performance. - System Integration and Collaboration
EXTOLL’s architectural contributions are foundational to achieving modular, configurable infrastructures that support both Rhea2-based and EPAC/EUPILOT-based processor modules. This enables the deployment of efficient and flexible cloud and edge computing applications, in collaboration with partners such as BSC, FORTH, SIGMA, RISE, and 2CSRi.
By combining its innovation in interconnect technology with leadership in system architecture, EXTOLL ensures that HIGHER’s open-source hardware and software ecosystem achieves maximum performance, scalability, and interoperability. Its pioneering work supports Europe’s strategic goal of advancing sovereign and energy-efficient HPC and cloud infrastructures, laying the groundwork for the next generation of high-performance computing systems.
