Algorithms and Parallel Computing

Book DescriptionB
There is a software gap between the hardware potential and the performance that can be attained using today抯 software parallel program development tools. The tools need manual intervention by the programmer to parallelize the code. Programming a parallel computer requires closely studying the target algorithm or application, more so than in the traditional sequential programming we have all learned. The programmer must be aware of the communication and data dependencies of the algorithm or application. This book provides the techniques to explore the possible ways to program a parallel computer for a given application.

A balanced overview of the techniques used to design and program parallel computers

There is a software gap between parallel computers and programmers?abilities to program such computers. Programming a parallel computer requires closely studying the target algorithm or application, more so than in traditional sequential programming. Today抯 programmer must be aware of the communication and data dependencies of the algorithm or application; yet, programmers do not have the tools to help them implement an algorithm on a parallel computer platform. This book provides the techniques necessary to explore parallelism in algorithms, serial as well as iterative. It shows how to systematically design special-purpose parallel processing structures to implement algorithms.

The book begins by explaining how to classify an algorithm, and then identifying which technique would be appropriate to implement the application on a parallel platform. It provides techniques for studying and analyzing several types of algorithms梡arallel, serial-parallel, non-serial-parallel, and regular iterative algorithms. New techniques for extracting parallelism and controlling thread workload are shown for the first time, such as z-transform, graphic, algebraic, and nonlinear workload specification for the threads. Also featured in the book:

A review of algorithms and how to parallelize each algorithm category
Ten case studies, detailed in separate chapters, that address implementing parallel algorithms on multithreaded parallel computers and developing special-purpose parallel machines
A chapter dedicated to enhancing single processor performance
End-of-chapter problems (solutions and lecture notes are available)
Algorithms and Parallel Computing is intended for application developers, researchers, and graduate students and seniors in computer engineering, electrical engineering, and computer science. Software developers and major computer manufacturers will also find the material highly beneficial.

Book Description
This book assumes familiarity with threads (in a language such as Ada, C#, or Java) and introduces the entity-life modeling (ELM) design approach for certain kinds of multithreaded software. ELM focuses on 搑eactive systems,?which continuously interact with the problem environment. These 搑eactive systems?include embedded systems, as well as such interactive systems as cruise controllers and automated teller machines.

Part I covers two fundamentals: program-language thread support and state diagramming. These are necessary for understanding ELM and are provided primarily for reference. Part II covers ELM from different angles. Part III positions ELM relative to other design approaches.

From the Back Cover
揃o Sanden has written a splendid book that should be read by every developer of systems that interact with the real world. The multi-threading theme that gives the book its title treats the identification and design of individual threads梩hat is, of concurrent processes梐nd the synchronisation and control of their interactions at common entities. The book succeeds excellently in this difficult area, expounding patterns of thread interaction that clarify both the problems they address and the solutions they offer.?br />桵ichael A. Jackson, from the Foreword

A novel approach to designing software for reactive systems

This book is the first available in-depth introduction to the cutting-edge entity-life modeling (ELM) approach for the design of multithreaded, reactive software, making it an instant authoritative reference. The text is divided into three parts:

Part I covers two fundamentals necessary for understanding ELM梡rogram-language thread support in Ada and Java, and state modeling
Part II describes ELM抯 unique approach
Part III positions ELM relative to other design approaches
Reactive software must respond to events in the world as they occur. To deal with this, ELM defines an event thread as a series of event occurrences that are separated in time. As the book reveals, event threads become the basis for software threads, leading to thread architectures that can be understood intuitively in problem-domain terms. Readers will discover how ELM captures the logic of event threads in terms of states, providing two patterns for designing software threads based on state diagrams and their activities.

Event threads in the domain can also form patterns. The text explains how ELM identifies the resource-user-thread pattern and the resource-guard-thread pattern, both addressing resource sharing by multiple domain entities. It also covers the case where entities need simultaneous exclusive access to more than one resource, and shows how ELM deals with deadlock prevention.

Design of Multithreaded Software is intended for software designers, architects, and researchers as well as systems designers, programmers, and engineers interested in a practical account of this novel approach.

Book Description
Details a real-world product that applies a cutting-edge multi-core architecture

Increasingly demanding modern applications梥uch as those used in telecommunications networking and real-time processing of audio, video, and multimedia streams梤equire multiple processors to achieve computational performance at the rate of a few giga-operations per second. This necessity for speed and manageable power consumption makes it likely that the next generation of embedded processing systems will include hundreds of cores, while being increasingly programmable, blending processors and configurable hardware in a power-efficient manner.

Multi-Core Embedded Systems presents a variety of perspectives that elucidate the technical challenges associated with such increased integration of homogeneous (processors) and heterogeneous multiple cores. It offers an analysis that industry engineers and professionals will need to understand the physical details of both software and hardware in embedded architectures, as well as their limitations and potential for future growth.

Discusses the available programming models spread across different abstraction levels

The book begins with an overview of the evolution of multiprocessor architectures for embedded applications and discusses techniques for autonomous power management of system-level parameters. It addresses the use of existing open-source (and free) tools originating from several application domains梥uch as traffic modeling, graph theory, parallel computing and network simulation. In addition, the authors cover other important topics associated with multi-core embedded systems, such as:

Architectures and interconnects
Embedded design methodologies
Mapping of applications
Programming paradigms and models of computation
Power optimization and reliability issues
Performance tools and benchmarks
Resource management
Multi-core programming challenges
Compiler and operating system support
This is a detailed discussion of research on the interaction between multi-core systems, applications and software views, and processor configuration and extension, which add a new dimension to the problem space. The text offers a useful overview of the most widespread industrial and domain-specific solutions, providing several examples of working implementations.

Book Description
Focusing on grid computing and asynchronism, Parallel Iterative Algorithms explores the theoretical and practical aspects of parallel numerical algorithms. Each chapter contains a theoretical discussion of the topic, an algorithmic section that fully details implementation examples and specific algorithms, and an evaluation of the advantages and drawbacks of the algorithms. Several exercises also appear at the end of most chapters.

The first two chapters introduce the general features of sequential iterative algorithms and their applications to numerical problems. The book then describes different kinds of parallel systems and parallel iterative algorithms. It goes on to address both linear and nonlinear parallel synchronous and asynchronous iterative algorithms for numerical computation, with an emphasis on the multisplitting approach. The final chapter discusses the features required for efficient implementation of asynchronous iterative algorithms.

Providing the theoretical and practical knowledge needed to design and implement efficient parallel iterative algorithms, this book illustrates how to apply these algorithms to solve linear and nonlinear numerical problems in parallel environments, including local, distant, homogeneous, and heterogeneous clusters.

In Parallel Iterative Algorithms: From Sequential to Grid Computing, Bahi, Contassot-Vivier, and Couturier bring mathematical formalism to the study of parallel iterative solution techniques, creating a book that will be useful to those with a strong maths background who are making the transition into parallel scientific computing. ?a great fit as a part of a graduate-level course on scientific computing in the math department, or for those already in scientific computing seeking to understand the key mathematical foundations of the analysis of iterative techniques. ?The authors execute their mission well, making sure that they treat the mathematical theory of each method in just enough detail to be complete. ?The combination of the theory and the implementation is valuable, and I found it illuminating to revisit algorithms I only knew at an implementation level from the mathematical perspective and to understand the reasons behind behaviors I had always taken as given. ?a nice addition to your HPC bookshelf in that it brings a strong focus on mathematical formalism, which is often lacking in more computing-oriented approaches to numerical methods. ?the book is loaded with citations, and readers looking for a different point of view or for more in depth material on a particular point will find a wealth of pointers to the literature.

Book Description
Your CPU meter shows a problem. One core is running at 100 percent, but all the other cores are idle. Your application is CPU-bound, but you are using only a fraction of the computing power of your multicore system. Is there a way to get better performance?

The answer, in a nutshell, is parallel programming. Where you once would have written the kind of sequential code that is familiar to all programmers, you now find that this no longer meets your performance goals. To use your system抯 CPU resources efficiently, you need to split your application into pieces that can run at the same time. Of course, this is easier said than done. Parallel programming has a reputation for being the domain of experts and a minefield of subtle, hard-to-reproduce software defects. Everyone seems to have a favorite story about a parallel program that did not behave as expected because of a mysterious bug.

These stories should inspire a healthy respect for the difficulty of the problems you will face in writing your own parallel programs. Fortunately, help has arrived. The Parallel Patterns Library (PPL) and the Asynchronous Agents Library introduce a new programming model for parallelism that significantly simplifies the job. Behind the scenes are sophisticated algorithms that dynamically distribute computations on multicore architectures. In addition, Microsoft?Visual Studio?2010 development system includes debugging and analysis tools to support the new parallel programming model.

Proven design patterns are another source of help. This guide introduces you to the most important and frequently used patterns of parallel programming and provides executable code samples for them, using PPL. When thinking about where to begin, a good place to start is to review the patterns in this book. See if your problem has any attributes that match the six patterns presented in the following chapters. If it does, delve more deeply into the relevant pattern or patterns and study the sample code.

You抣l travel through the IP layers and learn how they can create increased network traffic for you. You抣l see how to account for persistence and state, and how you can judge the performance of scheduling algorithms.

You抣l then learn how to avoid performance degradation and any risk of the sudden disappearance of a service on a server. If you抮e concerned with running your load balancer for an entire network, you抣l find out how to set up your network topography, and condense each topographical variety into recipes that will serve you in different situations. You抣l also learn about individual servers, and load balancers that can perform cookie insertion or improve your SSL throughput.

You抣l also explore load balancing in the modern context of the cloud. While load balancers need to be configured for high availability once the conditions on the network have been created, modern load balancing has found its way into the cloud, where good balancing is vital for the very functioning of the cloud, and where IPv6 is becoming ever more important.

You can read Practical Load Balancing from end to end or out of sequence, and indeed, if there are individual topics that interest you, you can pick up this book and work through it once you have read the first three chapters.
