An overview of the most prominent contemporary parallel processing programming models, written in a unique tutorial style. With the coming of the parallel computing era, computer scientists have turned their attention to designing programming models that are suited for high-performance parallel computing and supercomputing systems. Programming parallel systems is complicated by the fact that multiple processing units are simultaneously computing and moving data. This book offers an overview of some of the most prominent parallel programming models used in high-performance computing and supercomputing systems today. The chapters describe the programming models in a unique tutorial style rather than using the formal approach taken in the research literature. The aim is to cover a wide range of parallel programming models, enabling the reader to understand what each has to offer. The book begins with a description of the Message Passing Interface (MPI), the most common parallel programming model for distributed memory computing. It goes on to cover one-sided communication models, ranging from low-level runtime libraries (GASNet, OpenSHMEM) to high-level programming models (UPC, GA, Chapel); task-oriented programming models (Charm++, ADLB, Scioto, Swift, CnC) that allow users to describe their computation and data units as tasks so that the runtime system can manage computation and data movement as necessary; and parallel programming models intended for on-node parallelism in the context of multicore architecture or attached accelerators (OpenMP, Cilk Plus, TBB, CUDA, OpenCL). The book will be a valuable resource for graduate students, researchers, and any scientist who works with data sets and large computations. Contributors Timothy Armstrong, Michael G.

The hardware consists of a simple microcontroller, board, and chipset. It comes with a Java-based IDE to allow creators to program the board. Arduino is the ideal open hardware platform for experimenting with the world of the Internet of Things. This credit card sized Arduino board can be used via the Internet to make more useful and interactive Internet of things projects. Internet of Things with Arduino Blueprints is a project-based book that begins with projects based on IoT and cloud computing concepts. This book covers up to eight projects that will allow devices to communicate with each other, access information over the Internet, store and retrieve data, and interact with users-creating smart, pervasive, and always-connected environments. It explains how wired and wireless Internet connections can be used with projects and the use of various sensors and actuators. The main aim of this book is to teach you how Arduino can be used for Internet-related projects so that users are able to control actuators, gather data from various kinds of sensors, and send and receive data wirelessly across HTTP and TCP protocols. Finally, you can use these projects as blueprints for many other IoT projects and put them to good use. By the end of the book, you will be an expert in the use of IoT with Arduino to develop a set of projects that can relate very well to IoT applications in the real world. Style and approach Every chapter in this book clearly explains how to assemble components through easy-to-follow steps on while laying out important concepts, code snippets, and expected output results so that you can easily end up with a successful project where you can also enhance or modify the project according to your requirements.

High-performance computing refers to the use of advanced computing technologies, especially supercomputers, to solve highly complex, numerically intensive problems in the shortest possible time. Field programmable gate arrays (FPGAs) are emerging in many areas of high performance computing. FPGAs are so flexible and reconfigurable that they are capable of massively parallel operations, explicitly tailored to the problem at hand. There are many of paradigms to put FPGAs at work in a high performance computing environment. There are also many of limitations which restrict FPGAs to reach the performance of application Specific Integrated Circuits (ASICs) but they provide the possibility of changing the hardware design easily while outpacing software implementations on general purpose processors. Since FPGAs offer an inherently parallel computing paradigm The problem of achieving significant speedups on a new architecture without expending exorbitant development effort, while retaining flexibility, portability, and maintainability, is a classic one.

This is the era of automation. It is possible to alter the physical environment automatically through the use of computerized chips and protocols. The most basic use of this technology can be seen in the form of automated lights - the luminosity automatically turns on when a specific measurable level of darkness is crossed. At any level of luminosity above this, the lamps remain off. With Arduino, this has been made infinitely easier. Arduino produces single board microcontrollers which serve the purpose of a moderator/controller. Contained in the following pages is a detailed guide pertaining to the wonders of a microcontroller. It also covers the ways in which you can personalize it according to your specific needs. Keep reading to find out everything about Arduino

The most popular device used for a solution of plenty of DSP problems is CORDIC processor for orthogonal transformation of a plane rotation by Volder's algorithm. This algorithm have been employed in a number of special purpose processor arrays due to efficient realization of various types of linear transformations using simple hardware components. The dimensionality of CORDIC-algorithms is equal to two. This is the major disadvantage. A long sequence of these macro-operations is required for practical problem solving. Taking into account that very fast growth of modern VLSI technology offers a hardware realization of an ever-growing share of mathematical means it seems reasonable to speed up matrix computations by expressing them in terms of higher dimensional transformations. The present book is a short survey of research results which were published by author in this area for resent years.
