Supercomputing Frontiers Europe 2018
Title: Supercomputing Security or Supercomputing for Security
Bailey Whitfield ‘Whit’ Diffie (born June 5, 1944) is an American cryptographer and one of the pioneers of public-key cryptography. Diffie and Martin Hellman’s 1976 paper New Directions in Cryptography introduced a radically new method of distributing cryptographic keys, that helped solve key distribution—a fundamental problem in cryptography. Their technique became known as Diffie–Hellman key exchange. The article stimulated the almost immediate public development of a new class of encryption algorithms, the asymmetric key algorithms.
After a long career at Sun Microsystems, where he became a Sun Fellow, Diffie served for two and a half years as Vice President for Information Security and Cryptography at the Internet Corporation for Assigned Names and Numbers (2010–2012). He has also served as a visiting scholar (2009–2010) and affiliate (2010–2012) at the Freeman Spogli Institute’s Center for International Security and Cooperation at Stanford University.
Together with Martin Hellman, Diffie won the 2015 Turing Award, widely considered the most prestigious award in the field of computer science. The citation for the award was: “For fundamental contributions to modern cryptography. Diffie and Hellman’s groundbreaking 1976 paper, ‘New Directions in Cryptography’, introduced the ideas of public-key cryptography and digital signatures, which are the foundation for most regularly-used security protocols on the internet today.

Karlheinz Meier was appointed full professor of physics at Heidelberg University in 1992, where he co-founded the Kirchhoff-Institute for Physics. He has more than 25 years of experience in experimental particle physics, including design of a large-scale electronic data processing system that enabled the discovery of the Higgs Boson in 2012. Around 2005 he became interested in large-scale electronic implementations of brain-inspired computer architectures. His group pioneered several innovations in the field. He led 2 major European initiatives, FACETS and BrainScaleS. In 2009 he was one of the initiators of the European Human Brain Project (HBP) that was approved in 2013. In the HBP he leads the subproject on neuromorphic computing with the goal of establishing brain-inspired computing paradigms as research tools for neuroscience and generic hardware systems for cognitive computing. In the HBP he is a member of the project directorate and vice-chair of the science and infrastructure board.
Neuromorphic computing holds the promise to transfer computational advantages from biological brains to artificial silicon or new material based systems. Advantages include energy efficiency, fault tolerance and, most importantly, the ability to learn continuously from unstructured data. Recent advances in artificial intelligence are based on ANNs which represent extreme simplifications of biological architectures. In particular they ignore the time domain of neural signaling which plays a key role for learning and development of neural systems. In the lecture I will deliver an overview of novel brain-inspired neuromorphic hardware architectures. Particular emphasis will be given to the role of biological principles like spike based plasticity and active dendritic trees for computation. I will also discuss the recent releases of neuromorphic systems for general use and the opportunities they offer to advance both, neuroscience and machine learning.

Computing with Data Flow Engines: The Next Step for Supercomputing
Dr. Tobias Becker is the Head of MaxAcademy at Maxeler Technologies where he coordinates various research activities and Maxeler’s university program. Before joining Maxeler he been has held positions as a researcher in the Department of Computing at Imperial College London, and at Xilinx, Inc. He received a Ph.D. degree in Computing from Imperial College London and a Dipl. Ing. degree in Electrical Engineering from the Technical University of Karlsruhe (now KIT). His research work covers topics in reconfigurable computing, custom accelerators, self-adaptive systems, low-power optimisations, and financial applications.
Data Flow Engines (DFEs) are the next generation of data processing technology beyond CPUs and GPUs. Their low power consumption and performance density address the challenges that the computing industry today faces because of stagnating performance gains in conventional CPUs. DFEs are a departure from the typical Von Neumann architecture. Instead of bringing data to be processed to the CPU, the processing occurs as the data flows through large parallel processing structures on the DFE chip. As a result, the bottlenecks of centralised processing, complex memory hierarchies and time-consuming data transfers are removed. The distributed processing architecture of DFEs supports the free flow of data through the system where data arrives at exactly the right time and location to be processed much like in an industrial assembly line. The integration of DFEs with large amount of memory enables data-centric processing where Databases and hard drives are only needed in the backend for long term storage. The benefits of Dataflow processing have been demonstrated across many application domains including machine learning, finance, security and scientific computations.

Benoit Dupont de Dinechin
Manycore Accelerators beyond GPU Architecture
Benoît Dupont de Dinechin is Chief Technology Officer of Kalray. He is the Kalray VLIW core main architect, and the co-architect of the Multi-Purpose Processing Array (MPPA) processors. Benoît also defined the Kalray software roadmap and contributed to its implementation. Before joining Kalray, Benoît was in charge of Research and Development of the STMicroelectronics Software, Tools, Services division, and was promoted to STMicroelectronics Fellow in 2008. Prior to STMicroelectronics, Benoît worked at the Cray Research park (Minnesota, USA), where he designed the software pipeliner of the Cray T3E production compilers. Benoît earned an engineering degree in Radar and Telecommunications from the Ecole Nationale Supérieure de l’Aéronautique et de l’Espace (Toulouse, France), and a doctoral degree in computer systems from the University Pierre et Marie Curie (Paris) under the direction of Prof. P. Feautrier. He completed his post-doctoral studies at the McGill University (Montreal, Canada) at the ACAPS laboratory led by Prof. G. R. Gao.
High-end GPU processors implement a throughput-oriented architecture that has been highly successful for CPU acceleration in supercomputers and datacentres. GPUs can be characterized as manycore processors, that is, parallel processors where a large number of cores are distributed across compute units. Each GPU compute unit or «streaming multiprocessor» is composed of multi-threaded processing cores sharing a control unit, a local memory and a global memory hierarchy. However effective, GPU architecture entails significant limitations in the areas of expressiveness of programming environments, effectiveness on diverging parallel computations, and execution time predictability.
We discuss the architectural options and programming models of accelerators designed to address high-performance applications ranging from embedded to extreme computing. Similarly to GPU architectures, such accelerators comprise multiple compute units connected by on-chip global fabrics to external memory systems and network interfaces. Selecting compute units composed of fully programmable cores, coprocessors and asynchronous data transfer engines enable to match the acceleration performance and energy efficiency of GPU processors, while avoiding their limitations. This discussion is illustrated by the co-design of the 3rd-generation MPPA manycore processor for automated driving, and is related to the implication of Kalray in the Mont-Blanc 2020 and the European Processor Initiative projects that target exascale computing.

He holds more than 25 issued patents, and has co-organized 7 IEEE conferences. Over the years (32), IBM has awarded Ronald with three outstanding technical achievement awards and a corporate patent award.
The DOME MicroDataCenter, developed by IBM Zurich Research and ASTRON Netherlands Institute for Radio Astronomy, brings together the embedded and data-center computing worlds, resulting in the densest general-purpose computing capability with top energy-efficiency. I will describe this 5 year project and illustrate how we went from an initial idea through obtaining funding for our small team and to building innovative hard- and software. I explain how we used first-principles from physics to motivate key decisions, highlight some of the practical technical obstacles we needed to overcome and summarize key lessons we learnt along our way. Our result, which we are currently bringing to market through a new startup company, addresses the needs of edge-computing (analytics) for the Internet of Things.
