Performance Engineering für Modelltransformationen
Zusammenfassung der Projektergebnisse
Model-Driven-Engineering advocates using models and model transformations as primary and key artifacts in the development process. The used models, e.g., in the automotive domain and for the performance prediction of information systems, can become huge leading to long and unpredictable execution times when running model transformations. The starting point of the project was existing research as well as personal experience showing that optimizing model transformations to improve the execution time by refactoring them is possible. However, current model transformation languages and tools do not assist the software engineer in that endeavour as the execution of the model transformation is a black box to the software engineer and, hence, those activities did require expert knowledge about how the model transformation engines interact with the transformation script. For the first time the MICE project now breaks up this black box and enables software engineers to understand how model transformations are executed and assists in improving its performance. We initially conducted an extensive empirical study to summarize the current state of performance engineering for model transformation, i.e., how relevant is performance for engineers of model transformations and what are impediments and strategies used to improve the performance. This empirical study did confirm that performance is highly relevant and specific support is needed. Based on these results, we developed the first performance engineering approach for model transformations. This approach supports (1) an in-depth monitoring w.r.t. to performance characteristics, (2) an analysis of the monitored data on different levels of granularity, and (3) a visualization of the analysis data opening up the black box of model transformation execution. Additionally, we developed a machine learning based performance prediction approach which enables developers to predict the likely performance of a model transformation based on size and structure of potential future input models. The approach has been applied to two different classes of model transformation languages – the operational model transformation language QVT-o and the declarative model transformation languages Henshin and ATL. The quantitative and qualitative evaluation of the results did show that the monitoring only results in a small overhead and that engineers were able to understand the visualized analysis results, were able to identify root causes of performance problems, and were able to propose solutions for the performance problems.
