Book Synopsis Software Performability: From Concepts to Applications by : Ann T. Tai
Download or read book Software Performability: From Concepts to Applications written by Ann T. Tai and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computers are currently used in a variety of critical applications, including systems for nuclear reactor control, flight control (both aircraft and spacecraft), and air traffic control. Moreover, experience has shown that the dependability of such systems is particularly sensitive to that of its software components, both the system software of the embedded computers and the application software they support. Software Performability: From Concepts to Applications addresses the construction and solution of analytic performability models for critical-application software. The book includes a review of general performability concepts along with notions which are peculiar to software performability. Since fault tolerance is widely recognized as a viable means for improving the dependability of computer system (beyond what can be achieved by fault prevention), the examples considered are fault-tolerant software systems that incorporate particular methods of design diversity and fault recovery. Software Performability: From Concepts to Applications will be of direct benefit to both practitioners and researchers in the area of performance and dependability evaluation, fault-tolerant computing, and dependable systems for critical applications. For practitioners, it supplies a basis for defining combined performance-dependability criteria (in the form of objective functions) that can be used to enhance the performability (performance/dependability) of existing software designs. For those with research interests in model-based evaluation, the book provides an analytic framework and a variety of performability modeling examples in an application context of recognized importance. The material contained in this book will both stimulate future research on related topics and, for teaching purposes, serve as a reference text in courses on computer system evaluation, fault-tolerant computing, and dependable high-performance computer systems.

Book Synopsis Model-Based Software Performance Analysis by : Vittorio Cortellessa
Download or read book Model-Based Software Performance Analysis written by Vittorio Cortellessa and published by Springer Science & Business Media. This book was released on 2011-05-05 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: Poor performance is one of the main quality-related shortcomings that cause software projects to fail. Thus, the need to address performance concerns early during the software development process is fully acknowledged, and there is a growing interest in the research and software industry communities towards techniques, methods and tools that permit to manage system performance concerns as an integral part of software engineering. Model-based software performance analysis introduces performance concerns in the scope of software modeling, thus allowing the developer to carry on performance analysis throughout the software lifecycle. With this book, Cortellessa, Di Marco and Inverardi provide the cross-knowledge that allows developers to tackle software performance issues from the very early phases of software development. They explain the basic concepts of performance analysis and describe the most representative methodologies used to annotate and transform software models into performance models. To this end, they go all the way from performance primers through software and performance modeling notations to the latest transformation-based methodologies. As a result, their book is a self-contained reference text on software performance engineering, from which different target groups will benefit: professional software engineers and graduate students in software engineering will learn both basic concepts of performance modeling and new methodologies; while performance specialists will find out how to investigate software performance model building.

Book Synopsis Stochastic Models for Fault Tolerance by : Katinka Wolter
Download or read book Stochastic Models for Fault Tolerance written by Katinka Wolter and published by Springer Science & Business Media. This book was released on 2010-06-17 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: As modern society relies on the fault-free operation of complex computing systems, system fault-tolerance has become an indispensable requirement. Therefore, we need mechanisms that guarantee correct service in cases where system components fail, be they software or hardware elements. Redundancy patterns are commonly used, for either redundancy in space or redundancy in time. Wolter’s book details methods of redundancy in time that need to be issued at the right moment. In particular, she addresses the so-called "timeout selection problem", i.e., the question of choosing the right time for different fault-tolerance mechanisms like restart, rejuvenation and checkpointing. Restart indicates the pure system restart, rejuvenation denotes the restart of the operating environment of a task, and checkpointing includes saving the system state periodically and reinitializing the system at the most recent checkpoint upon failure of the system. Her presentation includes a brief introduction to the methods, their detailed stochastic description, and also aspects of their efficient implementation in real-world systems. The book is targeted at researchers and graduate students in system dependability, stochastic modeling and software reliability. Readers will find here an up-to-date overview of the key theoretical results, making this the only comprehensive text on stochastic models for restart-related problems.

Book Synopsis Integration of Performance Management into the Application Lifecycle by : Eduard Tudenhöfner
Download or read book Integration of Performance Management into the Application Lifecycle written by Eduard Tudenhöfner and published by diplom.de. This book was released on 2011-09-15 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inhaltsangabe:Introduction: Despite the widespread recognition that performance is important to the success of a project, many software products fail to respond fast enough to user requests or to handle a certain amount of parallel business transactions. This is because nowadays projects are result-oriented where the focus is on functionality to be implemented. Such projects do not pay high attention to application performance because it still does not have the particular importance that unit testing for example has. Moreover today s development models usually consider performance management only in a limited way within their lifecycle and often follow what is known as the fix it later approach. The fix it later approach concentrates on software correctness and defers performance considerations to the integration testing phase where additional hardware is added or a system is tuned when performance issues are detected. The problem of neglecting performance management is that performance issues often do not emerge until an application is put into production, where it is likely to suffer the consequences of a performance failure. The consequences of performance failures can be increased operational costs, increased development and hardware costs, and damaged customer relations. If severe performance issues are discovered during production, it may be too expensive to re-design a system or even impossible to add additional hardware in order to meet performance objectives. Such projects are likely to be canceled and their costs will be unrecoverable. To avoid such situations, performance management should be integrated into an application s lifecycle from the beginning. This means that performance objectives have to be defined early within a project and continually verified as an application evolves. Having performance management integrated from the beginning allows to reduce overall project risk and costs because performance issues can be spotted and corrected early in the lifecycle and even before end users are affected. Furthermore an application is extensively tested for its ability of reaching performance objectives before it is deployed to a production environment and exposed to real users. NovaTec GmbH is a company providing IT-services in the area of consulting, project management, software engineering, application architectures, provisioning, performance management, and process engineering.

Book Synopsis Performance Benchmarking of Application Monitoring Frameworks by : Jan Waller
Download or read book Performance Benchmarking of Application Monitoring Frameworks written by Jan Waller and published by BoD – Books on Demand. This book was released on 2014-12-19 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Application-level monitoring of continuously operating software systems provides insights into their dynamic behavior, helping to maintain their performance and availability during runtime. Such monitoring may cause a significant runtime overhead to the monitored system, depending on the number and location of used instrumentation probes. In order to improve a system’s instrumentation and to reduce the caused monitoring overhead, it is necessary to know the performance impact of each probe. While many monitoring frameworks are claiming to have minimal impact on the performance, these claims are often not backed up with a detailed performance evaluation determining the actual cost of monitoring. Benchmarks can be used as an effective and affordable way for these evaluations. However, no benchmark specifically targeting the overhead of monitoring itself exists. Furthermore, no established benchmark engineering methodology exists that provides guidelines for the design, execution, and analysis of benchmarks. This thesis introduces a benchmark approach to measure the performance overhead of application-level monitoring frameworks. The core contributions of this approach are 1) a definition of common causes of monitoring overhead, 2) a general benchmark engineering methodology, 3) the MooBench micro-benchmark to measure and quantify causes of monitoring overhead, and 4) detailed performance evaluations of three different application-level monitoring frameworks. Extensive experiments demonstrate the feasibility and practicality of the approach and validate the benchmark results. The developed benchmark is available as open source software and the results of all experiments are available for download to facilitate further validation and replication of the results.
