Download or read book Analyzing Computer System Performance with Perl PDQ written by Neil J. Gunther and published by Springer Science & Business Media. This book was released on 2011-07-30 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: To solve performance problems in modern computing infrastructures, often comprising thousands of servers running hundreds of applications, spanning multiple tiers, you need tools that go beyond mere reporting. You need tools that enable performance analysis of application workflow across the entire enterprise. That's what PDQ (Pretty Damn Quick) provides. PDQ is an open-source performance analyzer based on the paradigm of queues. Queues are ubiquitous in every computing environment as buffers, and since any application architecture can be represented as a circuit of queueing delays, PDQ is a natural fit for analyzing system performance. Building on the success of the first edition, this considerably expanded second edition now comprises four parts. Part I contains the foundational concepts, as well as a new first chapter that explains the central role of queues in successful performance analysis. Part II provides the basics of queueing theory in a highly intelligible style for the non-mathematician; little more than high-school algebra being required. Part III presents many practical examples of how PDQ can be applied. The PDQ manual has been relegated to an appendix in Part IV, along with solutions to the exercises contained in each chapter. Throughout, the Perl code listings have been newly formatted to improve readability. The PDQ code and updates to the PDQ manual are available from the author's web site at www.perfdynamics.com

Download or read book Guerrilla Capacity Planning written by Neil J. Gunther and published by Springer Science & Business Media. This book was released on 2007-01-17 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under today’s shortened fiscal horizons and contracted time-to-market schedules, traditional approaches to capacity planning are seen by management as inflating production schedules. In the face of relentless pressure to get things done faster, this book facilitates rapid forecasting of capacity requirements, based on opportunistic use of available performance data and tools so that management insight is expanded but production schedules are not. The book introduces such concepts as an iterative cycle of improvement called "The Wheel of Capacity Planning," and Virtual Load Testing, which provides a highly cost-effective method for assessing application scalability.

Download or read book Mastering Algorithms with Perl written by Jarkko Hietaniemi and published by "O'Reilly Media, Inc.". This book was released on 1999-08-18 with total page 708 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many programmers would love to use Perl for projects that involve heavy lifting, but miss the many traditional algorithms that textbooks teach for other languages. Computer scientists have identified many techniques that a wide range of programs need, such as: Fuzzy pattern matching for text (identify misspellings!) Finding correlations in data Game-playing algorithms Predicting phenomena such as Web traffic Polynomial and spline fitting Using algorithms explained in this book, you too can carry out traditional programming tasks in a high-powered, efficient, easy-to-maintain manner with Perl.This book assumes a basic understanding of Perl syntax and functions, but not necessarily any background in computer science. The authors explain in a readable fashion the reasons for using various classic programming techniques, the kind of applications that use them, and -- most important -- how to code these algorithms in Perl.If you are an amateur programmer, this book will fill you in on the essential algorithms you need to solve problems like an expert. If you have already learned algorithms in other languages, you will be surprised at how much different (and often easier) it is to implement them in Perl. And yes, the book even has the obligatory fractal display program.There have been dozens of books on programming algorithms, some of them excellent, but never before has there been one that uses Perl.The authors include the editor of The Perl Journal and master librarian of CPAN; all are contributors to CPAN and have archived much of the code in this book there."This book was so exciting I lost sleep reading it."

Download or read book Programming Multicore and Many core Computing Systems written by Sabri Pllana and published by John Wiley & Sons. This book was released on 2017-01-23 with total page 522 pages. 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 Modern B Tree Techniques written by Goetz Graefe and published by Now Publishers Inc. This book was released on 2011 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invented about 40 years ago and called ubiquitous less than 10 years later, B-tree indexes have been used in a wide variety of computing systems from handheld devices to mainframes and server farms. Over the years, many techniques have been added to the basic design in order to improve efficiency or to add functionality. Examples include separation of updates to structure or contents, utility operations such as non-logged yet transactional index creation, and robust query processing such as graceful degradation during index-to-index navigation. Modern B-Tree Techniques reviews the basics of B-trees and of B-tree indexes in databases, transactional techniques and query processing techniques related to B-trees, B-tree utilities essential for database operations, and many optimizations and improvements. It is intended both as a tutorial and as a reference, enabling researchers to compare index innovations with advanced B-tree techniques and enabling professionals to select features, functions, and tradeoffs most appropriate for their data management challenges.

Download or read book Posthuman Management written by Matthew E. Gladden and published by Defragmenter Media. This book was released on 2016-08-07 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: What are the best practices for leading a workforce in which human employees have merged cognitively and physically with electronic information systems and work alongside social robots, artificial life-forms, and self-aware networks that are ‘colleagues’ rather than simply ‘tools’? How does one manage organizational structures and activities that span actual and virtual worlds? How are the forces of technological posthumanization transforming the theory and practice of management? This volume explores the reality that an organization’s workers, managers, customers, and other stakeholders increasingly comprise a complex network of human agents, artificial agents, and hybrid human-synthetic entities. The first part of the book develops the theoretical foundations of an emerging ‘organizational posthumanism’ and presents frameworks for understanding and managing the evolving workplace relationship between human and synthetic beings. Other chapters investigate topics such as the likelihood that social robots might utilize charismatic authority to lead human workers; potential roles of AIs as managers of cross-cultural virtual teams; the ethics and legality of entrusting organizational decision-making to spatially diffuse robots that have no discernible physical form; quantitative approaches to comparing managerial capabilities of human and artificial agents; the creation of artificial life-forms that function as autonomous enterprises competing against human businesses; neural implants as gateways that allow human users to participate in new forms of organizational life; and the implications of advanced neuroprosthetics for information security and business model design. As the first comprehensive application of posthumanist methodologies to management, this volume will interest management scholars and management practitioners who must understand and guide the forces of technologization that are rapidly reshaping organizations’ form, dynamics, and societal roles.

Download or read book The Handbook of Information Security for Advanced Neuroprosthetics written by Matthew E. Gladden and published by Synthypnion Academic. This book was released on 2017-02-20 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does one ensure information security for a computer that is entangled with the structures and processes of a human brain – and for the human mind that is interconnected with such a device? The need to provide information security for neuroprosthetic devices grows more pressing as increasing numbers of people utilize therapeutic technologies such as cochlear implants, retinal prostheses, robotic prosthetic limbs, and deep brain stimulation devices. Moreover, emerging neuroprosthetic technologies for human enhancement are expected to increasingly transform their human users’ sensory, motor, and cognitive capacities in ways that generate new ‘posthumanized’ sociotechnological realities. In this context, it is essential not only to ensure the information security of such neuroprostheses themselves but – more importantly – to ensure the psychological and physical health, autonomy, and personal identity of the human beings whose cognitive processes are inextricably linked with such devices. InfoSec practitioners must not only guard against threats to the confidentiality and integrity of data stored within a neuroprosthetic device’s internal memory; they must also guard against threats to the confidentiality and integrity of thoughts, memories, and desires existing within the mind the of the device’s human host. This second edition of The Handbook of Information Security for Advanced Neuroprosthetics updates the previous edition’s comprehensive investigation of these issues from both theoretical and practical perspectives. It provides an introduction to the current state of neuroprosthetics and expected future trends in the field, along with an introduction to fundamental principles of information security and an analysis of how they must be re-envisioned to address the unique challenges posed by advanced neuroprosthetics. A two-dimensional cognitional security framework is presented whose security goals are designed to protect a device’s human host in his or her roles as a sapient metavolitional agent, embodied embedded organism, and social and economic actor. Practical consideration is given to information security responsibilities and roles within an organizational context and to the application of preventive, detective, and corrective or compensating security controls to neuroprosthetic devices, their host-device systems, and the larger supersystems in which they operate. Finally, it is shown that while implantable neuroprostheses create new kinds of security vulnerabilities and risks, they may also serve to enhance the information security of some types of human hosts (such as those experiencing certain neurological conditions).
