Available in PDF, EPUB and Kindle. Book excerpt: Building Resilient Systems brings together key concepts and methods to meet crucial challenges of energy-efficient system resilience. Computer system design is undergoing a paradigm shift in the wake of several disruptive trends: (a) CMOS device technology scaling is becoming progressively more difficult; yield and cost concerns are very high as fabrication capabilities get consolidated to just a few vendors; (b) the power and reliability walls provide major obstacles to the goal of improving hardware performance at historical levels; (c) computing paradigms in the era of internet-of-things (IOT) are evolving towards a more networked, distributed model. This book presents a modern perspective on how to build resilient computer systems, emphasizing reliability without incurring unaffordable levels of overhead, such as processor chip area, net system power or performance degradation. The late CMOS era design constraints impose hard limits on chip-level power density, current density and thermal profiles. Various kinds of transient and permanent failure mechanisms as well as low-yield concerns are on the rise, and the power wall makes it impractical to go for massively redundant architectures. The author advocates the use of cross-layer, hardware-software co-design techniques to minimize the power and cost overhead, while maximizing performance and system resilience. The book provides new generation modeling methods, cross-layer optimization and trade-off analysis techniques as well cross-layer error tolerant system architectures that will be needed for the future. Covers cross-layer resilience modeling, a new technique to optimize energy consumption across system layers Explains the necessary tradeoffs to provide targeted system resilience without blowing the cost or power budget Presents application-driven compute engines that offer cost-effective solutions for big data analytics, cloud or mobile computing, or cognitive systems without compromising end-user quality and system availability Includes case studies illustrating examples of embedded, server, and supercomputing systems

Available in PDF, EPUB and Kindle. Book excerpt: Data centers consume roughly 1% of the total electricity demand, while ICT as a whole consumes around 10%. Demand is growing exponentially and, left unchecked, will grow to an estimated increase of 20% or more by 2030. This book covers the energy consumption and minimization of the different data center components when running real workloads, taking into account the types of instructions executed by the servers. It presents the different air- and liquid-cooled technologies for servers and data centers with some real examples, including waste heat reuse through adsorption chillers, as well as the hardware and software used to measure, model and control energy. It computes and compares the Power Usage Effectiveness and the Total Cost of Ownership of new and existing data centers with different cooling designs, including free cooling and waste heat reuse leading to the Energy Reuse Effectiveness. The book concludes by demonstrating how a well-designed data center reusing waste heat to produce chilled water can reduce energy consumption by roughly 50%, and how renewable energy can be used to create net-zero energy data centers.

Available in PDF, EPUB and Kindle. Book excerpt: The Information and communication technology (ICT) industry is said to account for 2% of the worldwide carbon emissions – a fraction that continues to grow with the relentless push for more and more sophisticated computing equipment, c- munications infrastructure, and mobile devices. While computers evolved in the directionofhigherandhigherperformanceformostofthelatterhalfofthe20thc- tury, the late 1990’s and early 2000’ssaw a new emergingfundamentalconcern that has begun to shape our day-to-day thinking in system design – power dissipation. As we elaborate in Chapter 1, a variety of factors colluded to raise power-ef?ciency as a ?rst class design concern in the designer’s mind, with profound consequences all over the ?eld: semiconductor process design, circuit design, design automation tools, system and application software, all the way to large data centers. Power-ef?cient System Design originated from a desire to capture and highlight the exciting developments in the rapidly evolving ?eld of power and energy op- mization in electronic and computer based systems. Tremendous progress has been made in the last two decades, and the topic continues to be a fascinating research area. To develop a clearer focus, we have concentrated on the relatively higher level of design abstraction that is loosely called the system level. In addition to the ext- sive coverage of traditional power reduction targets such as CPU and memory, the book is distinguished by detailed coverage of relatively modern power optimization ideas focussing on components such as compilers, operating systems, servers, data centers, and graphics processors.

Download or read book Circuits and Systems Advances in Near Threshold Computing written by Sanghamitra Roy and published by MDPI. This book was released on 2021-05-11 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern society is witnessing a sea change in ubiquitous computing, in which people have embraced computing systems as an indispensable part of day-to-day existence. Computation, storage, and communication abilities of smartphones, for example, have undergone monumental changes over the past decade. However, global emphasis on creating and sustaining green environments is leading to a rapid and ongoing proliferation of edge computing systems and applications. As a broad spectrum of healthcare, home, and transport applications shift to the edge of the network, near-threshold computing (NTC) is emerging as one of the promising low-power computing platforms. An NTC device sets its supply voltage close to its threshold voltage, dramatically reducing the energy consumption. Despite showing substantial promise in terms of energy efficiency, NTC is yet to see widescale commercial adoption. This is because circuits and systems operating with NTC suffer from several problems, including increased sensitivity to process variation, reliability problems, performance degradation, and security vulnerabilities, to name a few. To realize its potential, we need designs, techniques, and solutions to overcome these challenges associated with NTC circuits and systems. The readers of this book will be able to familiarize themselves with recent advances in electronics systems, focusing on near-threshold computing.

Available in PDF, EPUB and Kindle. Book excerpt: Since the end of Dennard scaling in the early 2000s, improving the energy efficiency of computation has been the main concern of the research community and industry. The large energy efficiency gap between general-purpose processors and application-specific integrated circuits (ASICs) motivates the exploration of customizable architectures, where one can adapt the architecture to the workload. In this Synthesis lecture, we present an overview and introduction of the recent developments on energy-efficient customizable architectures, including customizable cores and accelerators, on-chip memory customization, and interconnect optimization. In addition to a discussion of the general techniques and classification of different approaches used in each area, we also highlight and illustrate some of the most successful design examples in each category and discuss their impact on performance and energy efficiency. We hope that this work captures the state-of-the-art research and development on customizable architectures and serves as a useful reference basis for further research, design, and implementation for large-scale deployment in future computing systems.

Download or read book Design of Stochastic Computing Architectures Using Integrated Optics written by Hassnaa El-Derhalli and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximate computing (AC) is an emerging computing approach that allows to trade off design energy efficiency with computing accuracy. It targets error resilient applications, such as image processing, where energy consumption is of major concern. Stochastic computing (SC) is an approximate computing paradigm that leads to energy efficient and reduced hardware complexity designs. In this approach, data is represented as probabilities in bit streams format. The main drawback of this computing paradigm is the intrinsic serial processing of bit streams, which negatively impacts the processing time. Nanophotonics technology is characterized by high bandwidth and high signals propagation speed, which has the potential to support the electrical domain in computations to speed up the processing rate. The major issues in optical computing (OC) remain the large size of silicon photonics devices, which impact the design scalability. In this thesis, we propose, for the first time, an optical stochastic computing (OSC) approach, where we aim to design SC architectures using integrated optics. For this purpose, we propose a methodology that has libraries for optical processing and interfaces, e.g., bit stream generator. We design all-optical gates for the computation and develop transmission models for the architectures. The methodology allows for design space exploration of technological and system-level parameters to optimize design performance, i.e., energy efficiency, computing accuracy, and latency, for the targeted application. This exploration leads to multiple design options that satisfy different design requirements for the selected application. The optical processing libraries include designing a polynomial architecture that can execute any arbitrary single input function. We explore the design parameters by implementing a Gamma correction application for image processing. Results show a 4.5x increase in the errors, which leads to 47x energy saving and 16x faster processing speed. We propose a reconfigurable polynomial architecture to adapt design order at run-time. The design allows the execution of high order polynomial functions for better accuracy or multiple low order functions to increase throughput and energy efficiency. Finally, we propose the design of combinational filters. The purpose is to investigate the design of cascaded gates architectures using photonic crystal (PhC) nanocavities. We use this device to design a Sobel edge detection filter for image processing. The resulting architecture shows 0.85nJ/pixel energy consumption and 51.2ns/pixel processing time. The optical interface libraries include designing different architectures of stochastic number generators (SNG) that are either electrical-optical or all-optical to generate the bit streams. We compare these SNGs in terms of computing accuracy and energy efficiency. The results show that all implementations can lead to the same level of computing accuracy. Moreover, using an all-optical SNG to design a fully optical 8-bit adder results in 98% reduction in hardware complexity and 70% energy saving compared to a conventional optical design.

Download or read book Designing for Resilience written by Vanessa Rodrigues and published by Linköping University Electronic Press. This book was released on 2020-05-05 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Services are prone to change in the form of expected and unexpected variations and disruptions, more so given the increasing interconnectedness and complexity of service systems today. These changes require service systems to be resilient and designed to adapt, to ensure that services continue to work smoothly. This thesis problematises the prevailing view and assumptions underpinning the current understanding of resilience in services. Drawing on literature from service management, service design, systems thinking and social-ecological resilience theory, this work investigates how service design can foster resilience in service systems. Supported by empirical input from three research projects in healthcare, the findings show service design can contribute to the adaptability and transformability of service systems through its holistic, human-centred, participatory and experimental approaches. Through the analysis, this research identifies key intervention points for cultivating service systems resilience through service design, including the design of service interactions, processes, enabling structures and multi-level governance. The study makes two important contributions. First, it extends the understanding of service systems resilience as the collective capacity for intentional action in responding to ongoing change, coordinated across scales in order to create value. This is supported by offering alternative assumptions about resilience in service. Second, it positions service design as an enabler of service resilience by explicitly linking design practice(s) to processes that contribute to resilience. By extending the understanding of service systems resilience, this thesis lays the groundwork for future research at the intersection of service design, systemic change and resilience.
