The EPI Processor and its Robustness Requirements”, Yingchih Yang, Lead Architect for the European Processor Initiative (EPI) project

Abstract: The European Processor Initiative (EPI) represents the ambition of Europe in the High Performance Computing (HPC) field. It aims to develop critical technologies and generate key components for next generation HPC systems with primary focus on the EPI high-performance low-energy-consumption processor. In this talk we will present the project and vision of the team, and the robustness challenges of the EPI processor.

PATMOS Keynote Talk

Contactless Integrated Systems for “More than Moore” Applications”, Prof. Vasilis F. Pavlidis, Advanced Processor Technologies group, University of Manchester, UK Abstract: The idea of ubiquitous computing with 30 billion connected devices in service by 2020, ranging from micro-scale biomedical implanted chips, to portable and wearable electronics, and high performance data centres, has become an ambitious objective of this decade. Building such a diverse and complex ecosystem requires integration strategies that go beyond traditional objectives, for example, speed and area and enable new features, such as technological and functional heterogeneity, reusability, and disposability. This talk discusses a low cost, low form-factor and energy efficient integration technology where the classic wired interconnections are replaced by contactless links deployed to underpin low power applications, such as lab-on-chip systems. The advantages over the state-of-the-art, typically based on conventional wired interconnects, and the challenges for delivering these systems are described along with a methodology for the energy efficient design of these systems by exploiting heterogeneous CMOS processes. Additional considerations including cost, design tools, and modeling processes are also presented, highlighting all the diverse aspects of the ecosystem that need to be addressed towards the high volume manufacturing of contactless integrated systems.

IOLTS Keynote Talk

From Research to Product: RAS Features in EPYC and Radeon Instinct”, Vilas Sridharan, AMD Fellow, RAS (Reliability, Availability, and Serviceability) Architecture group, AMD Abstract: The explosive growth of cloud-scale computing is a defining feature of the modern era. The datacenters that power modern clouds contain hundreds of thousands of compute nodes, each powered by highly integrated and powerful processors and compute accelerators. Provisioning adequate levels of reliability and availability for these nodes is a technical challenge, as even rare events can occur frequently at such scale. Addressing this challenge requires significant investment in research and development to understand the events that occur at scale and to design an appropriate set of features to address them. This talk will discuss reliability research conducted by AMD and describe how the results of this research affected the architecture, design, and implementation of certain reliability, availability, and serviceability (RAS) features in AMD EPYC and Radeon Instinct products.
