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 novel energy-efficient cloud architecture.

Specifically, RISER will build two cloud-focused platforms:

1. An accelerator platform, which includes the Arm RHEA SoC from EPI and a PCIe acceleration board to be developed within the project which will integrate up-to four RISC-V based chips from EUPILOT.
2. A microserver platform, interconnecting up to ten microserver boards all developed by the project, each one supporting up to four RISC-V chips coupled with high-speed storage and networking. Embracing hyperconvergence, our microserver architecture allows for distributed storage and memory to be used by any processor in the system with low overhead. The open-source system board designs of RISER will be accompanied by open-source low-level firmware and systems software, and a representative Linux-based software stack to support cloud services, facilitating uptake and enhancing the commercialization path of project results.
