Available in PDF, EPUB and Kindle. Book excerpt: Programming multi-core and many-core computing systems Sabri Pllana, Linnaeus University, Sweden Fatos Xhafa, Technical University of Catalonia, Spain Provides state-of-the-art methods for programming multi-core and many-core systems The book comprises a selection of twenty two chapters covering: fundamental techniques and algorithms; programming approaches; methodologies and frameworks; scheduling and management; testing and evaluation methodologies; and case studies for programming multi-core and many-core systems. Program development for multi-core processors, especially for heterogeneous multi-core processors, is significantly more complex than for single-core processors. However, programmers have been traditionally trained for the development of sequential programs, and only a small percentage of them have experience with parallel programming. In the past, only a relatively small group of programmers interested in High Performance Computing (HPC) was concerned with the parallel programming issues, but the situation has changed dramatically with the appearance of multi-core processors on commonly used computing systems. It is expected that with the pervasiveness of multi-core processors, parallel programming will become mainstream. The pervasiveness of multi-core processors affects a large spectrum of systems, from embedded and general-purpose, to high-end computing systems. This book assists programmers in mastering the efficient programming of multi-core systems, which is of paramount importance for the software-intensive industry towards a more effective product-development cycle. Key features: Lessons, challenges, and roadmaps ahead. Contains real world examples and case studies. Helps programmers in mastering the efficient programming of multi-core and many-core systems. The book serves as a reference for a larger audience of practitioners, young researchers and graduate level students. A basic level of programming knowledge is required to use this book.

Download or read book Parallel Programming written by Thomas Rauber and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innovations in hardware architecture, like hyper-threading or multicore processors, mean that parallel computing resources are available for inexpensive desktop computers. In only a few years, many standard software products will be based on concepts of parallel programming implemented on such hardware, and the range of applications will be much broader than that of scientific computing, up to now the main application area for parallel computing. Rauber and Rünger take up these recent developments in processor architecture by giving detailed descriptions of parallel programming techniques that are necessary for developing efficient programs for multicore processors as well as for parallel cluster systems and supercomputers. Their book is structured in three main parts, covering all areas of parallel computing: the architecture of parallel systems, parallel programming models and environments, and the implementation of efficient application algorithms. The emphasis lies on parallel programming techniques needed for different architectures. The main goal of the book is to present parallel programming techniques that can be used in many situations for many application areas and which enable the reader to develop correct and efficient parallel programs. Many examples and exercises are provided to show how to apply the techniques. The book can be used as both a textbook for students and a reference book for professionals. The presented material has been used for courses in parallel programming at different universities for many years.

Download or read book Computer Architecture for Scientists written by Andrew A. Chien and published by Cambridge University Press. This book was released on 2022-03-10 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dramatic increase in computer performance has been extraordinary, but not for all computations: it has key limits and structure. Software architects, developers, and even data scientists need to understand how exploit the fundamental structure of computer performance to harness it for future applications. Ideal for upper level undergraduates, Computer Architecture for Scientists covers four key pillars of computer performance and imparts a high-level basis for reasoning with and understanding these concepts: Small is fast – how size scaling drives performance; Implicit parallelism – how a sequential program can be executed faster with parallelism; Dynamic locality – skirting physical limits, by arranging data in a smaller space; Parallelism – increasing performance with teams of workers. These principles and models provide approachable high-level insights and quantitative modelling without distracting low-level detail. Finally, the text covers the GPU and machine-learning accelerators that have become increasingly important for mainstream applications.

Available in PDF, EPUB and Kindle. Book excerpt: Limited power budgets and the need for high performance computing have led toplatform customization with a number of accelerators integrated with many-coreCPUs. The design space of architectures with CPUs and accelerators forms acontinuum with varying degrees of specialization in execution data paths, memories,data communication and control. In order to study customized architectures, thisdissertation focuses on computer vision workloads and architectures optimized toimplement these workloads. Exploiting similarities in computer vision workloads,this dissertation presents configurable functional units or accelerators thatimplement frequently performed operations in these workloads and optimized forenergy-efficiency. A detailed study of how to map workloads on accelerators ispresented.This dissertation models customization design points and compares theirperformance and energy across a number of computer vision workloads. Thelimitations of generic architectures are analyzed and the costs and benefits ofincreasing customization using these micro-architectural design points is quantified.The sources of performance and energy efficiency in customized architectures areidentified. The impact of a)specialized functional units b)local memories optimizedfor specific memory access pattern c) optimization of data transfer from externalmemories into local memories, and from local memories into functional unitregisters is studied in detail. This analysis leads us to develop a frameworkconsisting of low-power multi-cores and an array of configurable micro-acceleratorfunctional units, performing the best for the chosen domain of computer visionworkloads. Using this platform, this dissertation illustrates data flow and controlprocessing optimizations that provide for performance gains similar to customASICs for vision benchmarks.The scaling of such systems with multi core processors to larger and larger numberof cores and integration with a large number of optimized accelerators substantiallyincreases both computation and data transfers. A comprehensive design-spaceexploration of multi core architectures and accelerators with shared memories usingcycle-accurate full-chip simulators or design and synthesis is becoming impracticaldue to prohibitive simulation times. In order to study the impact of sharingmemories and data flow between local memories in CPUs and local memories inaccelerators, there is a need for fast, accurate and scalable models that aid in systemarchitecture design space exploration. Therefore, this dissertation presents ananalytical model that abstracts the processing unit, and characterizes it in terms ofmemory interaction alone. The presented model, Performance Estimation throughContention ANalysis (PECAN), is a tool that models various uncore components,and estimates per-core performance in multi core architectures and accelerators.Using the developed framework, this dissertation carries out a fast uncore design space exploration of multi core processors with accelerators.
