This book was released on 2014-09-22 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growing number of cores increases the demand for a powerful memory subsystem which leads to enhancement in the size of caches in multicore processors. Caches are responsible for giving processing elements a faster, higher bandwidth local memory to work with. This text presents an analysis to study the impact of cache size on performance of Multi-core processors by varying L1 and L2 cache size on the multicore processor with internal network (MPIN) referenced from NIAGRA architecture. The effect of interconnections on the performance of multicore processors has been analyzed and a novel scalable, on-chip interconnection mechanism (INOC) for multicore processors has been proposed. A full system simulator multi2sim has been used to analyze the performance of different proposed architectures using Splash2 benchmark.

Book Synopsis Performance Optimization of Multi-core Processors Using Core Hopping - Thermal and Structural by : Sunil Lingampalli
Download or read book Performance Optimization of Multi-core Processors Using Core Hopping - Thermal and Structural written by Sunil Lingampalli and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As the work load on the single core processor increases, it's processing speed increases resulting in increased power densities and die temperatures. The increase in die temperature results in decreased performance and reliability and increased leakage currents and cooling costs. In order to decrease the work load and the cooling cost on the single core processor, multi-core processors have been implemented. Multicore Processors also known as Chip Multi Processors (CMP's) are the processors which contain two or more independent cores on a chip. In CMPs, if one core reaches its critical temperature, the workload is transferred to the other. This phenomenon is termed as core hopping. Also, the non-uniform power distribution across the die is not uniform, resulting in hot spots. Core hopping results in the uniform distribution of the work load among the many cores and leads to performance and reliability improvement. The demand for greater performance in applications involving high levels of computing has resulted in many cores being put on a single chip. Every succeeding processor is predicted to hold double the number of cores than previous one. In this study, core hopping for CMPs is analyzed and thermal analysis of the chip is performed using ANSYS. Furthermore, the hop sequence will be optimized as a function of chip temperature distribution and thermo-mechanical analysis of the package will be carried out to estimate its structural integrity.

Download or read book Core Monitors written by Paul Edwin West and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Performance counters are becoming more complex as multi-core systems are becoming more wide spread. Consequently, evaluating these counters has become more complex as well. We propose providing hardware that monitors performance counters, namely in multi-core systems, in order to make decisions for improving performance. For instance, a piece of hardware watching snoop packets may be able to determine when a write-update cache coherence protocol would be helpful or detrimental to the current running program. Furthermore, watching memory traffic through a shared cache can determine if a program on a certain CPU is memory-bound. Once a program on a CPU is determined memory bound, the kernel can be informed to schedule accordingly. Finally, these new counters may be used to facilitate obtaining profile data for the compiler. We have implemented monitors in a full system simulator and found performance improvement.

Book Synopsis Parallel Programming by : Thomas Rauber
Download or read book Parallel Programming written by Thomas Rauber and published by Springer Science & Business Media. This book was released on 2010-03-16 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.

Book Synopsis Parallel Computing Architectures and APIs by : Vivek Kale
Download or read book Parallel Computing Architectures and APIs written by Vivek Kale and published by CRC Press. This book was released on 2019-12-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parallel Computing Architectures and APIs: IoT Big Data Stream Processing commences from the point high-performance uniprocessors were becoming increasingly complex, expensive, and power-hungry. A basic trade-off exists between the use of one or a small number of such complex processors, at one extreme, and a moderate to very large number of simpler processors, at the other. When combined with a high-bandwidth, interprocessor communication facility leads to significant simplification of the design process. However, two major roadblocks prevent the widespread adoption of such moderately to massively parallel architectures: the interprocessor communication bottleneck, and the difficulty and high cost of algorithm/software development. One of the most important reasons for studying parallel computing architectures is to learn how to extract the best performance from parallel systems. Specifically, you must understand its architectures so that you will be able to exploit those architectures during programming via the standardized APIs. This book would be useful for analysts, designers and developers of high-throughput computing systems essential for big data stream processing emanating from IoT-driven cyber-physical systems (CPS). This pragmatic book: Devolves uniprocessors in terms of a ladder of abstractions to ascertain (say) performance characteristics at a particular level of abstraction Explains limitations of uniprocessor high performance because of Moore’s Law Introduces basics of processors, networks and distributed systems Explains characteristics of parallel systems, parallel computing models and parallel algorithms Explains the three primary categorical representatives of parallel computing architectures, namely, shared memory, message passing and stream processing Introduces the three primary categorical representatives of parallel programming APIs, namely, OpenMP, MPI and CUDA Provides an overview of Internet of Things (IoT), wireless sensor networks (WSN), sensor data processing, Big Data and stream processing Provides introduction to 5G communications, Edge and Fog computing Parallel Computing Architectures and APIs: IoT Big Data Stream Processing discusses stream processing that enables the gathering, processing and analysis of high-volume, heterogeneous, continuous Internet of Things (IoT) big data streams, to extract insights and actionable results in real time. Application domains requiring data stream management include military, homeland security, sensor networks, financial applications, network management, web site performance tracking, real-time credit card fraud detection, etc.
