The European Processor Initiative (EPI) https://www.european-processor-initiative.eu/, a project with 30 partners from 10 European countries, with the goal of achieving Europe’s independence in HPC chip technologies and infrastructure, is proud to announce the successful Manufacturing and Silicon Demonstration of its EPAC Accelerator chip version 1.5, marking a significant milestone in high-performance computing.

EPAC1.5 is a collection of RISC-V based accelerators designed to push the boundaries of acceleration technologies. This innovative test-chip showcases three distinct approaches to acceleration:

  1. General purpose CPU with dedicated vector unit (VPU)
  2. Many-core stencil/machine learning accelerator (STX)
  3. General Purpose CPU supporting variable precision (VRP)

The EPAC 1.5 design (Figure 1) contains vector processing micro-tiles (VPU) composed of the Avispado RISC-V core designed by SemiDynamics and a vector processing unit designed by Barcelona Supercomputing Center and the University of Zagreb.

Additional micro-tiles contain distributed Home Nodes (HN) and L2 cache slices (L2), designed respectively by Chalmers and FORTH-ICS, that provide a coherent view of the shared memory subsystem.

The chip also includes the Stencil and Tensor accelerator (STX) designed by ETH Zürich and Fraunhofer IIS and the variable precision processor (VRP) designed by CEA.

All accelerators are interconnected with a very high-speed network on chip with multiple crosspoints (XP) and an off-chip link using SERDES technology from EXTOLL.

The European High Performance Computing Joint Undertaking (EuroHPC JU) has launched 3 new research and innovation projects. The projects aim to bring the EU and its partners in the EuroHPC JU closer to developing independent microprocessor and HPC technology and advance a sovereign European HPC ecosystem. The European Processor Initiative (EPI SGA2), The European PILOT and the European Pilot for Exascale (EUPEX) are interlinked projects and an important milestone towards a more autonomous European supply chain for digital technologies and specifically HPC.

With joint investments of €140 million from the European Union (EU) and the EuroHPC JU Participating States, the three projects will carry out research and innovation activities to contribute to the overarching goal of securing European autonomy and sovereignty in HPC components and technologies, especially in anticipation of the European exascale supercomputers.

The three projects have been selected following two calls for proposals: H2020-JTI-EuroHPC-2020-01 for EUPEX and The European PILOT, and H2020-JTI-EuroHPC-2020-02 for EPI SGA2.

Anders Dam Jensen, the European High Performance Computing Joint Undertaking (EuroHPC JU) Executive Director, said:

“Developing a strong European HPC supply chain with independent components and technologies is key to achieve strategic autonomy and digital sovereignty in Europe. The three projects, EPI 2, EUPEX and The European PILOT are critical to make successful our transition towards exascale while developing a world-class, competitive and innovative supercomputing ecosystem across Europe.”

“The EPI consortium brings together the best industrial and academic expertise in Europe: it combines the best of both worlds, academic innovation with industrial strength. We are thrilled to be given the opportunity to build on the momentum generated by phase 1 of the project and continue to develop the technologies that will power future European exascale systems. We look forward to seeing our components (processors & accelerators) experimented and used – in pilot projects and beyond.” said Etienne Walter, Atos, the EPI Phase 2 General Manager.

“All members of the EUPEX consortium are extremely proud to participate in this pilot for exascale, a project on an unprecedented scale, which is the culmination of more than 10 years of European HPC research and development towards exascale supercomputing. EUPEX will crystallize the research efforts of many projects – from Mont-Blanc projects to DEEP projects – and validate EPI processors with all these European technologies within the framework of a coherent but modular pilot platform. EUPEX will pave the way for a self-reliant European HPC industry, capable of delivering exascale-class supercomputers manufactured in Europe.” said Jean-Robert Bacou, Atos, the EUPEX coordinator.

“The European Pilot project will contribute to a sustainable exascale HPC in Europe and it will help build the groundwork for long-term technical independence. Hardware wise, The European Pilot leverages and significantly scales up EPI advancements built from scratch, such as EPAC, in the form of massively parallel arrangement of HPC vector and machine learning accelerators. These European-IP accelerators and customized software ecosystem will deliver near-exascale levels of performance at unparalleled levels of scale of integration. The European Pilot systems will be deployed in liquid immersion cooling tanks supporting ultra-efficient power densities. The know-how to build these supercomputers will help establish digital autonomy within the EU” said Carlos Puchol, Barcelona Supercomputing Center (BSC), the European Pilot coordinator.

European Processor Initiative (EPI)  

The consortium of the European Processor Initiative (EPI) started the second implementation phase of the initiative on 1 January 2022. The project is implemented under the framework partnership agreement in European low-power microprocessor technologies which focuses on microprocessor technologies to develop competitive European technology for HPC and other applications.

Central goals of the initiative are:

The second implementation phase of the EPI will continue the initial developments of the phase 1 on a European microprocessor and accelerator to support European technological autonomy and sovereignty in this critical area. Based on a solid, long-term economic approach, the EPI will deliver central components of future European supercomputers to boost innovation and the digital transformation of the European economy.

The specific focus of the second phase is to finalise the development of the first generation of low-power microprocessor units and accelerators, enhancing existing technologies to target the incoming European Exascale machines, develop the second generation of and ensuring paths for industrialisation and commercialisation of these technologies.

The microprocessors units are leveraging on Arm architecture, and the accelerators on Risc-V instruction set architecture. The EPI has established close links to two pilots towards the European exascale supercomputers where the developed technology will be demonstrated and made available for software development.

The project is coordinated by Atos (Bull SAS). It will run for 3 years with a budget of up to 70 million provided by the EU and the Participating States of the EuroHPC JU.

European Pilot for Exascale (EUPEX)

EUPEX was launched on 1st January 2022 and will develop the first European platform for HPC, gathering and integrating the full breadth of European technologies, from system architecture, processor, system software and development tools, all the way to applications. The EUPEX platform will be a production-grade prototype designed to be open and scalable, and leveraging the HPC technologies used and developed by its scientific and industrial partners. The pilot system will also serve as a development vehicle for software and applications in collaboration with European key user communities.

EUPEX aims to directly support an emerging and vibrant European entrepreneurial ecosystem around European HPC technology, addressing related sectors such as Artificial Intelligence (AI) and Big Data processing. It will be a vehicle to prepare communities working in HPC, AI and Big Data for the upcoming European Exascale systems and federated HPC infrastructure.

The project is coordinated by Atos (Bull SAS). It will run for 4 years with a budget of up to €40.7 million provided by the EU and the Participating States of the EuroHPC JU. EUPEX is linked to The European PILOT through a collaboration agreement to ensure an aligned evolution of European technology towards the next generation of supercomputers.

Pilot using Independent, Local and Open Technologies (The European PILOT)

From 1 December 2021, The European PILOT project (Pilot using Independent, Local and Open Technologies) started working on designing a European accelerator leveraging and extending developments within the framework partnership agreement in European low-power microprocessor technologies.

Accelerators typically provide most of the nominal floating-point performance in modern HPC systems and represent fundamental building blocks of current and future Exascale HPC systems. The European PILOT will demonstrate an accelerator on the basis of European technology and an open standard using the RISC-V instruction set architecture. The integration of accelerators into a highly dense pilot HPC system with liquid immersion cooling technologies will be an important contribution to the European HPC ecosystem.

The project is coordinated by the Barcelona Supercomputing Center (BSC) and brings together multiple partners to combine existing intellectual property with novel innovation as building blocks for future HPC systems.  The project will run for a period of 42 months with a budget of up to €30 million provided by the EU and the Participating States of the EuroHPC JU. The European PILOT is linked to EUPEX through a collaboration agreement to ensure an aligned evolution of European technology towards the next generation of supercomputers.

The European Processor Initiative (EPI) https://www.european-processor-initiative.eu/, a project with 28 partners from 10 European countries, with the goal of helping the EU achieve independence in HPC technologies is proud to announce that we have successfully booted Linux on our EPAC 1.0 core subset implemented on FPGA.

One key segment of EPI activities is to develop and demonstrate fully European processor IPs based on the RISC-V Instruction Set Architecture, providing power efficient and high throughput accelerator core named EPAC (European Processor Accelerator). Using RISC-V will allow leveraging open-source resources at hardware architecture level and software level, as well as ensuring independence from non-European patented computing technologies.

First silicon implementation of EPAC 1.0 test chip is expected in the second half of 2021 and as an important technical milestone towards that goal, we have successfully booted Linux on a subset of EPAC 1.0 synthesized on FPGA. The FPGA design includes the Avispado RISC-V core, the Vector Processing Unit (VPU), the Network on Chip (NoC), the Shared L2 Cache with Coherence Home Node (L2HN), interrupt controllers, IO peripherals and several other components. This implementation will enormously speed-up software development on the EPI HPC architecture as well as testing and improving the architecture for next generations EPAC chips.

 

Figure 1 FPGA emulation and EPAC Software Development Vehicle block diagram

 

For the development of the EPI Accelerator Test Chip, we make extensive use of FPGA technologies to verify the RTL design of the Test Chip. The subset of EPAC 1.0 emulated on FPGA we use as Software Development Vehicle (SDV) to enable early software development before the actual Test Chip silicon comes back from the foundry.

The use of FPGAs enables the testing of RTL blocks with real and very complex software in timescales that are not tractable using pure RTL simulation. Also, it allowed us to stress memory coherence and several related corner cases. We have managed to boot Linux using the EPAC 1.0 system on FPGA and the system boots within a few dozens of seconds compared to weeks using pure simulation. The system is fully usable and interactive for system software and application development and it also includes Ethernet connectivity to enable running large and complex software packages, e.g., OpenMP, MPI.

This is a serious proof of concept that gives us the confidence of a functional and viable future product.

More details on the results can also be found on EPI YouTube Channel, where you can find the second episode of EPI Talks podcast, themed with booting Linux:

This year’s HiPEAC conference was supposed to be held in beautiful Budapest, from January 18th to 20th 2021. However, due to the persistent pandemic conditions, it had to be moved to a digital edition.

European Processor Initiative’s consortium gladly accepted the opportunity to participate, both as a sponsor and with a tutorial given to the attendees. Our tutorial was held on Monday, January 18th, and it involved the following topics and presenters:

The tutorial was very well attended, and the attendees had a lot of interesting questions.

In addition to the tutorial, the EPI team has also hosted a virtual Brazen booth, where students, young researchers, and other prospective employees popped in to ask questions about the project. From the industrial side of EPI, Fabrizio Magugliani presented EPI in the industrial session, while Jurgen Becker attended the WRC workshop and gave an invited talk that involved EPI as well.

All of the presentations from HiPEAC given by EPI members can be found in our repository:

https://www.european-processor-initiative.eu/dissemination-material/epi-at-hipeac-2021/, while the tutorial video is also available on our YouTube Channel: https://www.youtube.com/watch?v=4AYDc6THtcM&t=9476s.

Finally, a shout-out to organizers: even though the team is more than eager to participate in the next one, hopefully live, HiPEAC conference, we are thankful to organizers for such a wonderful experience and the opportunity to share our views and ideas.

The European Processor Initiative, a project with 27 partners from 10 European countries, with the goal of helping the EU achieve independence in HPC technologies, is finishing its second year of activities.

Despite 2020 bringing upon our young efforts the circumstances that were previously unimaginable, causing the subsequent cancellation of the first-ever planned European Processor Initiative Forum, the partners in the Initiative managed to stay the course and maintain all activities in all designated streams.

The year began with our latest partner, SiPearl, launching to start their activities dedicated to developing commercialized implementations of our technology. Very soon after announcing their presence on the global stage, SiPearl signed a licensing agreement with Arm and opened a branch in Germany.

At the same time, European Processor Initiative partners have finalized the first version of our RISC-V accelerator architecture, named EPAC, and we look forward to the delivery of the first European Processor Initiative silicon featuring EPAC Test Chip in the exciting year that follows. The EPAC Test Chip silicon will be complemented with PCIe EPAC Test Platform enabling the test and enhancements of the architecture for future revisions.

At the software level, we already have a compiler supporting RISC-V vector intrinsics and automatic parallelization of C/C++ codes. We are evaluating the generated code on emulation platforms that provide detailed insight for the holistic co-design of applications, compiler, and architecture. We also have other software development vehicles (SDV) where we are adapting the Operating System for the Heterogeneous ARM+RISC-V architecture of the European Processor Initiative project.

Our automotive activities in the previous year have been focused on the design of state-of-the-art automotive high-performance computing proof-of-concept with the ambition to demonstrate how European Processor Initiative IP will enable future ADAS functionality, paving the way to exploit the GPP, the RISC-V platform, the Kalray MPPA, and the Menta eFPGA IP.

Based on this project progress, the Consortium is ready to announce the updated project roadmap shown below:

European Processor Initiative will, together with colleagues from other European exascale projects, attend the virtual Supercomputing20, where we will showcase our latest developments and update to the roadmap. We invite you to attend our virtual booth and join in the lively discussions about the future of HPC!

 

At this year’s first virtual Supercomputing 20, the European Processor Initiative has invited several European exascale projects to share our virtual booth and showcase their progress, ideas, and results. Representatives from all of the projects and the European Processor Initiative will be available at our online booth for video chats.

The projects are:

We look forward to your visiting our booth and booking appointments for video chats with any of our representatives!
