Download or read book Energy efficient Spatio temporal Computing Framework written by Wenchao Qian and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital system design incorporates components ranging from general purpose processors (GPPs) to application specific integrated circuits (ASICs). GPPs provide flexible implementation of diverse applications at the cost of high execution time, energy and area. On the other hand, ASICs provide high performance, low energy and area, but they are usually custom designed for one or two specific applications. Reconfigurable computing frameworks are the solutions in between. They can take advantages from both GPPs and ASICs. Field programmable gate arrays (FPGAs) have emerged as attractive reconfigurable computing frameworks. They have the flexibility to map a variety of applications with fast speed, low energy and area. FPGAs integrate spatially distributed memory arrays and programmable routing resources. Functions are realized inside the memory blocks as lookup tables (LUTs) and the interconnects take care of the communication between different memory blocks. However, the energy and area are dominated by the programmable interconnects. With newer technology generations, these interconnects are not scaling as well as logic gates. Therefore, a reconfigurable framework that minimizes the requirements of programmable interconnects is expected to improve performance, energy and area while technology continues advancing. This work proposes a novel reconfigurable computing framework for hardware acceleration, referred to as MAlleable Hardware Accelerator (MAHA). It uses a spatio-temporal computing model which aims at improving energy-efficiency of various algorithmic tasks. In each processing element (PE), the main computing is done by a memory block, which stores both data and LUTs. PEs are spatially distributed and communicate with each other through interconnects. The operation execution inside each PE is performed cycle by cycle in a temporal fashion. It significantly reduces the requirement of programmable interconnects compared to a fully spatial reconfigurable computing architecture, and hence it improves energy-efficiency. The scalability of such a framework is expected to be better than the fully spatial architectures because it drastically reduces the need for the programmable interconnect. Data can be read and executed locally inside each PE. Such a memory-centric computing platform provides a great opportunity to mitigate the off-chip bandwidth requirement between memory and computing engines in a conventional computing architecture.

Download or read book On Spatio Temporal Data Modelling and Uncertainty Quantification Using Machine Learning and Information Theory written by Fabian Guignard and published by Springer Nature. This book was released on 2022-03-12 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: The gathering and storage of data indexed in space and time are experiencing unprecedented growth, demanding for advanced and adapted tools to analyse them. This thesis deals with the exploration and modelling of complex high-frequency and non-stationary spatio-temporal data. It proposes an efficient framework in modelling with machine learning algorithms spatio-temporal fields measured on irregular monitoring networks, accounting for high dimensional input space and large data sets. The uncertainty quantification is enabled by specifying this framework with the extreme learning machine, a particular type of artificial neural network for which analytical results, variance estimation and confidence intervals are developed. Particular attention is also paid to a highly versatile exploratory data analysis tool based on information theory, the Fisher-Shannon analysis, which can be used to assess the complexity of distributional properties of temporal, spatial and spatio-temporal data sets. Examples of the proposed methodologies are concentrated on data from environmental sciences, with an emphasis on wind speed modelling in complex mountainous terrain and the resulting renewable energy assessment. The contributions of this thesis can find a large number of applications in several research domains where exploration, understanding, clustering, interpolation and forecasting of complex phenomena are of utmost importance.

Download or read book A Metascalable Computing Framework for Large Spatiotemporal Scale Atomistic Simulations written by and published by . This book was released on 2009 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A metascalable (or 'design once, scale on new architectures') parallel computing framework has been developed for large spatiotemporal-scale atomistic simulations of materials based on spatiotemporal data locality principles, which is expected to scale on emerging multipetaflops architectures. The framework consists of: (1) an embedded divide-and-conquer (EDC) algorithmic framework based on spatial locality to design linear-scaling algorithms for high complexity problems; (2) a space-time-ensemble parallel (STEP) approach based on temporal locality to predict long-time dynamics, while introducing multiple parallelization axes; and (3) a tunable hierarchical cellular decomposition (HCD) parallelization framework to map these O(N) algorithms onto a multicore cluster based on hybrid implementation combining message passing and critical section-free multithreading. The EDC-STEP-HCD framework exposes maximal concurrency and data locality, thereby achieving: (1) inter-node parallel efficiency well over 0.95 for 218 billion-atom molecular-dynamics and 1.68 trillion electronic-degrees-of-freedom quantum-mechanical simulations on 212,992 IBM BlueGene/L processors (superscalability); (2) high intra-node, multithreading parallel efficiency (nanoscalability); and (3) nearly perfect time/ensemble parallel efficiency (eon-scalability). The spatiotemporal scale covered by MD simulation on a sustained petaflops computer per day (i.e. petaflops · day of computing) is estimated as NT = 2.14 (e.g. N = 2.14 million atoms for T = 1 microseconds).

Download or read book Green Mobile Networks written by Nirwan Ansari and published by John Wiley & Sons. This book was released on 2017-03-22 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: Green communications is a very hot topic. As mobile networks evolve in terms of higher rates/throughput, a consequent impact on operating costs is due to (aggregate) network energy consumption. As such, design on 4G networks and beyond have increasingly started to focus on `energy efficiency’ or so-called ‘green’ networks. Many techniques and solutions have been proposed to enhance the energy efficiency of mobile networks, yet no book has provided an in-depth analysis of the energy consumption issues in mobile networks nor has detailed theories, tools and solutions for solving the energy efficiency problems. This book presents the techniques and solutions for enhancing energy efficiency of future mobile networks, and consists of three major parts. The first part presents a general description of mobile network evolution in terms of both capacity and energy efficiency. The second part discusses the advanced techniques to green mobile networks. The third part discusses the solutions that enhance mobile network energy efficiency as well as provides future directions. Whilst the reader is expected to have basic knowledge of wireless communications, the authors present a brief introduction of the evolution of mobile networks, providing the knowledge base for understanding the content of the book. In addition, complicated network problems are illustrated using simple examples. This will help the reader understand the concept and intuition of various techniques and solutions. Incorporates the latest research results from both academia and industry, providing an up-to-date overview of existing technologies and solutions on making mobile networks greener Consists of three sections with a gradually increasing technical depth on green mobile networks, providing the reader with a systematic view of the research area, and helping those with different technical backgrounds to better understand the content Covers existing enabling technologies for green mobile networking, including an innovative discussion of state-of-the-art solutions and algorithms

Download or read book Energy efficient Management of Reconfigurable Computers written by Rathijit Sen and published by . This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power and energy consumption are first-order constraints on the design and operation of computer systems today. Improving energy efficiency reduces the amount of energy needed to perform a given computation as well as enables more computation to be performed for the same amount of energy. This saves operational costs to use these systems as well as capital costs to provision for them. Conventionally, energy proportionality (energy consumption in proportion to the work done) as proposed by Barroso and H{\"{o}}lzle has been the gold standard of an ideal system's energy efficiency. While this model is valid for fixed-resource systems, modern systems are reconfigurable in many aspects, allowing them to adapt to changing workload characteristics. We show that reconfigurability invalidates the conventional notions of ideal energy proportionality if the system behaves super-proportionally providing more performance (or work) in proportion to the power (or energy) used. We propose a new ideal model, Energy Optimal Proportional (EOP), that subsumes the conventional model and improves upon it by also accounting for super-proportional systems. EOP can guide system designers to improve the maximum efficiency attainable over the operating range and forms a basis for comparisons of energy efficiency across systems. Power-performance Pareto optimality, on the other hand, can guide system operators to manage load and configure resources appropriately to make the current system execute efficiently. We propose a new intellectual framework that interrelates these two complementary energy efficiency goals. The rest of this dissertation focuses on energy-efficient management. We develop new reactive governors that coordinate processor frequency (and voltage) and hardware prefetching to improve energy efficiency on a real (Haswell) server. We also propose a space-efficient hardware mechanism to estimate temporal locality (reuse) in cache accesses. The estimated distributions can be used by our new analytical models for cache performance to drive resizing decisions of the last-level cache. Finally, we propose a new semantics-based classification system for system reconfiguration capabilities. We hope that this classification will be insightful to future researchers while exploring the space of reconfigurable systems, in categorizing existing work and in identifying coordination options that have been less well explored
