This book was released on 2014-04-10 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance modelling can require substantial effort when creating and maintaining performance models for software systems that are based on existing software. Therefore, this thesis addresses the challenge of performance prediction in such scenarios. It proposes a novel goal-oriented method for experimental, measurement-based performance modelling. We validated the approach in a number of case studies including standard industry benchmarks as well as a real development scenario at SAP.

Download or read book Performance Problem Diagnostics by Systematic Experimentation written by Wert, Alexander and published by KIT Scientific Publishing. This book was released on 2018-03-29 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, we introduce an automatic, experiment-based approach for performance problem diagnostics in enterprise software systems. The proposed approach systematically searches for root causes of detected performance problems by executing series of systematic performance tests. The presented approach is evaluated by various case studies showing that the presented approach is applicable to a wide range of contexts.

Download or read book Automated Experiments for Deriving Performance relevant Properties of Software Execution Environments written by Hauck, Michael and published by KIT Scientific Publishing. This book was released on 2014-02-11 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: The software execution environment can play a crucial role when analyzing the performance of a software system. In this book, a novel approach for the automated detection of performance-relevant properties of the execution environment is presented. The properties are detected using predefined experiments and integrated into performance prediction tools. The approach is applied to experiments for detecting different CPU, OS, and virtualization properties, and validated in different case studies.

Download or read book An Approach for Guiding Developers to Performance and Scalability Solutions written by Heger, Christoph and published by KIT Scientific Publishing. This book was released on 2018-09-05 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The quality of enterprise software applications plays a crucial role for the satisfaction of the users and the economic success of the enterprises. Software applications with unsatisfying performance and scalability are perceived by its users as low in quality, as less interesting and less attractive, and cause frustration when preventing the users from attaining their goals. This book proposes an approach for a recommendation system that enables developers who are novices in software perform.

Download or read book Model Based Performance Prediction for Concurrent Software on Multicore Architectures A Simulation Based Approach written by Frank, Markus Kilian and published by KIT Scientific Publishing. This book was released on 2022-07-18 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Die modellbasierte Performancevorhersage ist ein bekanntes Konzept zur Gewährleistung der Softwarequalität. Derzeitige Ansätze basieren auf einem Modell mit einer Metrik, was zu ungenauen Vorhersagen für moderne Architekturen führt. In dieser Arbeit wird ein Multi-Strategie-Ansatz zur Erweiterung von Performancevorhersagemodellen zur Unterstützung von Multicore-Architekturen vorgestellt, in Palladio implementiert und dadurch die Genauigkeit der Vorhersage deutlich verbessert. - Model-based performance prediction is a well-known concept to ensure the quality of software. Current approaches are based on a single-metric model, which leads to inaccurate predictions for modern architectures. This thesis presents a multi-strategies approach to extend performance prediction models to support multicore architectures. We implemented the strategies into Palladio and significantly increased the performance prediction power.

This book was released on 2018-12-11 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work developed an automatic approach for the assessment of software reliability which is both theoretical sound and practical. The developed approach extends and combines theoretical sound approaches in a novel manner to systematically reduce the overhead of reliability assessment.

Download or read book A Reference Structure for Modular Model based Analyses written by Koch, Sandro Giovanni and published by KIT Scientific Publishing. This book was released on 2024-04-25 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, the authors analysed the co-dependency between models and analyses, particularly the structure and interdependence of artefacts and the feature-based decomposition and composition of model-based analyses. Their goal is to improve the maintainability of model-based analyses. They have investigated the co-dependency of Domain-specific Modelling Languages (DSMLs) and model-based analyses regarding evolvability, understandability, and reusability.

Download or read book Building Transformation Networks for Consistent Evolution of Interrelated Models written by Klare, Heiko and published by KIT Scientific Publishing. This book was released on 2022-03-24 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex software systems are described with multiple artifacts, such as code, design diagrams and others. Ensuring their consistency is crucial and can be automated with transformations for pairs of artifacts. We investigate how developers can combine independently developed and reusable transformations to networks that preserve consistency between more than two artifacts. We identify synchronization, compatibility and orchestration as central challenges, and we develop approaches to solve them.

Download or read book Specification Languages for Preserving Consistency between Models of Different Languages written by Kramer, Max Emanuel and published by KIT Scientific Publishing. This book was released on 2019-01-30 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: When complex IT systems are being developed, the usage of several programming and modelling languages can lead to inconsistencies that yield faulty designs and implementations. To address this problem, this work contributes a classification of consistency preservation challenges and an approach for preserving consistency. It is formalized using set theory and monitors changes to avoid matching and diffing problems. Three new languages that follow this preservation approach are presented.

Download or read book Implicit Incremental Model Analyses and Transformations written by Hinkel, Georg and published by KIT Scientific Publishing. This book was released on 2021-07-20 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: When models of a system change, analyses based on them have to be reevaluated in order for the results to stay meaningful. In many cases, the time to get updated analysis results is critical. This thesis proposes multiple, combinable approaches and a new formalism based on category theory for implicitly incremental model analyses and transformations. The advantages of the implementation are validated using seven case studies, partially drawn from the Transformation Tool Contest (TTC).
