Available in PDF, EPUB and Kindle. Book excerpt: This survey explores the theory and practice of techniques to make computing systems faster or more energy-efficient by allowing them to make controlled errors. In the same way that systems which only use as much energy as necessary are referred to as being energy-efficient, you can think of the class of systems addressed by this survey as being error-efficient: They only prevent as many errors as they need to. The definition of what constitutes an error varies across the parts of a system. And the errors which are acceptable depend on the application at hand. In computing systems, making errors, when behaving correctly would be too expensive, can conserve resources. The resources conserved may be time: By making some errors, systems may be faster. The resource may also be energy: A system may use less power from its batteries or from the electrical grid by only avoiding certain errors while tolerating benign errors that are associated with reduced power consumption. The resource in question may be an even more abstract quantity such as consistency of ordering of the outputs of a system. This survey is for anyone interested in an end-to-end view of one set of techniques that address the theory and practice of making computing systems more efficient by trading errors for improved efficiency.
Book Synopsis Temporal Memoization for Energy-efficient Timing Error Recovery in GPGPU Architectures by : Abbas Rahimi
Download or read book Temporal Memoization for Energy-efficient Timing Error Recovery in GPGPU Architectures written by Abbas Rahimi and published by . This book was released on 2014 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Manufacturing and environmental variability lead to timing errors in computing systems that are typically corrected by error detection and correction mechanisms at the circuit level. The cost and speed of recovery can be improved by memoization-based optimization methods that exploit spatial or temporal parallelisms in suitable computing fabrics such as general-purpose graphics processing units (GPGPUs). We propose here a temporal memoization technique for use in floating-point units (FPUs) in GPGPUs that uses value locality inside data-parallel programs. The technique recalls (memorizes) the context of error-free execution of an instruction on a FPU. Therefore, it avoids redundant execution and saves energy for FPU. To enable scalable and independent recovery, a single-cycle lookup table (LUT) is tightly coupled to every FPU to maintain contexts of recent error-free executions. The LUT reuses these memorized contexts to exactly, or approximately, correct errant FP instructions based on application needs. In real-world applications, the temporal memoization technique achieves an average energy saving of 13% {25% for a wide range of timing error rates (0% {4%) and outperforms recent advances in resilient architectures. This technique also enhances robustness in the voltage overscaling regime and achieves relative average energy saving of 44% with 11% voltage overscaling.

Book Synopsis Energy-Efficient Distributed Computing Systems by : Albert Y. Zomaya
Download or read book Energy-Efficient Distributed Computing Systems written by Albert Y. Zomaya and published by John Wiley & Sons. This book was released on 2012-07-26 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: The energy consumption issue in distributed computing systems raises various monetary, environmental and system performance concerns. Electricity consumption in the US doubled from 2000 to 2005. From a financial and environmental standpoint, reducing the consumption of electricity is important, yet these reforms must not lead to performance degradation of the computing systems. These contradicting constraints create a suite of complex problems that need to be resolved in order to lead to 'greener' distributed computing systems. This book brings together a group of outstanding researchers that investigate the different facets of green and energy efficient distributed computing. Key features: One of the first books of its kind Features latest research findings on emerging topics by well-known scientists Valuable research for grad students, postdocs, and researchers Research will greatly feed into other technologies and application domains
Book Synopsis Design of Dependable Computing Systems by : J.C. Geffroy
Download or read book Design of Dependable Computing Systems written by J.C. Geffroy and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book analyzes the causes of failures in computing systems, their consequences, as weIl as the existing solutions to manage them. The domain is tackled in a progressive and educational manner with two objectives: 1. The mastering of the basics of dependability domain at system level, that is to say independently ofthe technology used (hardware or software) and of the domain of application. 2. The understanding of the fundamental techniques available to prevent, to remove, to tolerate, and to forecast faults in hardware and software technologies. The first objective leads to the presentation of the general problem, the fault models and degradation mechanisms wh ich are at the origin of the failures, and finally the methods and techniques which permit the faults to be prevented, removed or tolerated. This study concerns logical systems in general, independently of the hardware and software technologies put in place. This knowledge is indispensable for two reasons: • A large part of a product' s development is independent of the technological means (expression of requirements, specification and most of the design stage). Very often, the development team does not possess this basic knowledge; hence, the dependability requirements are considered uniquely during the technological implementation. Such an approach is expensive and inefficient. Indeed, the removal of a preliminary design fault can be very difficult (if possible) if this fault is detected during the product's final testing.

Book Synopsis Dependable Embedded Systems by : Jörg Henkel
Download or read book Dependable Embedded Systems written by Jörg Henkel and published by Springer Nature. This book was released on 2020-12-09 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Open Access book introduces readers to many new techniques for enhancing and optimizing reliability in embedded systems, which have emerged particularly within the last five years. This book introduces the most prominent reliability concerns from today’s points of view and roughly recapitulates the progress in the community so far. Unlike other books that focus on a single abstraction level such circuit level or system level alone, the focus of this book is to deal with the different reliability challenges across different levels starting from the physical level all the way to the system level (cross-layer approaches). The book aims at demonstrating how new hardware/software co-design solution can be proposed to ef-fectively mitigate reliability degradation such as transistor aging, processor variation, temperature effects, soft errors, etc. Provides readers with latest insights into novel, cross-layer methods and models with respect to dependability of embedded systems; Describes cross-layer approaches that can leverage reliability through techniques that are pro-actively designed with respect to techniques at other layers; Explains run-time adaptation and concepts/means of self-organization, in order to achieve error resiliency in complex, future many core systems.

Book Synopsis Energy Efficient Computing Using Static-dynamic Co-optimizations by : Karthik Gururaj
Download or read book Energy Efficient Computing Using Static-dynamic Co-optimizations written by Karthik Gururaj and published by . This book was released on 2013 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy consumption is a primary concern of current day computing systems -- from handheld battery operated systems to servers in data centers connected to wall power. Research in academia as well as industry has focused on a variety of techniques for minimizing energy consumption while maintaining a good level of performance. The most effective techniques combine the best of static (or offline) and dynamic (or online/runtime) optimizations to obtain the best solution. Static optimizations can be more complex and can afford to take a global view of the application/computation being executed on the system -- however, such optimizations have to be conservative in nature because they cannot anticipate all the different scenarios that can appear at runtime. Dynamic optimizations have more information about the application/computation for the given input -- however, since such optimizations have to have low overhead, they can afford to have only a local view of the computation/ application and the complexity of the optimization has to be relatively low. An additional direction that needs to be considered is to determine whether dynamic optimizations should be implemented in software or hardware. In this thesis, I present a study of three aspects of energy efficient computing that use a combination of static and dynamic optimizations to minimize energy consumption. The first aspect is to consider variability in the execution time of applications during scheduling for dynamic voltage frequency scaling (DVFS) capable systems to minimize energy consumption and yet maintain a desired level of performance. The main idea is to construct a schedule table offline and perform a simple table look-up at runtime. The second aspect is to consider application-level reliability for applications that can tolerate certain error in the outputs. I present the study of a profile-guided offline compilation strategy to identify critical instructions and a monitoring technique in software to handle corner cases at runtime. Finally, the third aspect of energy efficient computing I investigate is flexibility customizing the instruction sets of processors to improve energy efficiency. I study the benefits of compiler directed optimizations for generating custom instructions which are executed within a modified processor pipeline and an architecture mechanism for detecting corner cases and to roll-back to a safe state. Additionally, I investigate the benefits of customizing the instruction set dynamically in hardware.

Book excerpt: The Future of Numerical Computing Written by one of the foremost experts in high-performance computing and the inventor of Gustafson’s Law, The End of Error: Unum Computing explains a new approach to computer arithmetic: the universal number (unum). The unum encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This new number type obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power. A Complete Revamp of Computer Arithmetic from the Ground Up Richly illustrated in color, this groundbreaking book represents a fundamental change in how to perform calculations automatically. It illustrates how this novel approach can solve problems that have vexed engineers and scientists for decades, including problems that have been historically limited to serial processing. Suitable for Anyone Using Computers for Calculations The book is accessible to anyone who uses computers for technical calculations, with much of the book only requiring high school math. The author makes the mathematics interesting through numerous analogies. He clearly defines jargon and uses color-coded boxes for mathematical formulas, computer code, important descriptions, and exercises.
