An Approach for Performance Evaluation of Batch-sequential and Parallel Architectural Styles
Software architecture is considered one of the most important indices of software engineering today. Software Architecture is a technical description of a system indicating its component structures and their relationships, and is the principles and rules governing designing. Software Architecture can be utilized to materialize most of the important quality attributes in the system;and these qualities should be evaluated at architectural leveL Therefore, to what extent software architectural design has been successful depends on the quality attributes of the system. One of the most important quality attributes is the performance. Usually an architect takes into consideration in software architectural design is to use software architectural styles. An architecture style is a set of principles which an architect uses in designing software architecture. Since software architectural styles have frequently been used by architects, these styles have a specific effect on quality attributes. If this effect is measurable for each existing style, it will enable the architect to evaluate and make architectural decisions more easily and precisely. In this paper an effort has been made to introduce a model for investigating this attribute in Parallel and Batch-sequential styles. So, our approach initially models the system as Discrete Time Markov Chain or DTMC, and then extracts the parameters to predict the response time of Batchsequential and Parallel style. Then, in order to evaluate the systems whose architectures include both styles, we will generalize our model.
