Thus, firstly appropriate description methods for distributed intelligent applications are summarized. Derived from the system characterization, typical software performance engineering techniques are based on the augmented description of the model regarding performance annotations. However, these annotations are only related with the syntactical view of the software architecture. In the next generation of performance assessment tools for ambient intelligent systems, the description of the system would be capable of reasoning and acquiring knowledge about performance. Having an appropriate architectural description including performance aspects, any possible design options for intelligent distributed applications can be evaluated according to their performance impact. Therefore, we propose the use of an ontology with performance-related information not only to possible evaluate the architecture through the common off-line procedure but also the first step to build a broker that assesses the performance of the system during its execution.","PeriodicalId":235512,"journal":{"name":"Workshop on Software and Performance","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127891223","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The challenge is not to reinvent new analysis methods for UML models, but to bridge the gap between UML-based software development tools and different kinds of existing analysis tools. Traditionally, the analysis models were built \"by hand\". However, a new trend is starting to emerge, that involves the automatic transformation of UML models (annotated with extra information) into various kinds of analysis models. This paper proposes a transformation method of an annotated UML model into a performance model. The mapping between the input model and the output model is defined at a higher level of abstraction based on graph transformation concepts, whereas the implementation of the transformation rules and algorithm uses lower-level XML trees manipulations techniques, such as XML algebra. The target performance model used as an example in this paper is the Layered Queueing Network (LQN); however, the transformation approach can be easily tailored to other performance modelling formalisms.","PeriodicalId":235512,"journal":{"name":"Workshop on Software and Performance","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115195056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The same statement on one execution may exhibit redundant computation whereas on a different execution, it contributes to the program output. A redundant (dead) statement always exhibits redundant computation, i.e., its execution is always redundant. However, a statement that exhibits redundant computation is not necessarily a redundant statement. Redundant computation represents a partial redundancy of a statement. A high degree of redundant computation in a program may indicate a performance deficiency. Therefore, elimination (or reduction) of redundant computation may improve program's performance. In this paper we present an approach of automated detection of redundant computation in programs and show its application in performance analysis. We developed a tool that automatically detects redundant computations in C programs and identifies potential performance deficiencies related to redundant computation. We have performed an experimental study that showed that redundant computation is a commonly occurring phenomenon in programs, and it is frequently a source of performance deficiency.","PeriodicalId":235512,"journal":{"name":"Workshop on Software and Performance","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122774762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Performance properties, for instance, can be annotated on UML designs by using the \"UML Profile for Schedulability, Performance and Time (SPT)\". However the communication between the design description in UML and the tools used for non-functional properties evaluation requires support, particularly for performance where there are many alternative performance analysis tools that might be applied. This paper describes a tool architecture called PUMA, which provides a unified interface between different kinds of design information and different kinds of performance models, for example Markov models, stochastic Petri nets and process algebras, queues and layered queues.The paper concentrates on the creation of performance models. The unified interface of PUMA is centered on an intermediate model called Core Scenario Model (CSM), which is extracted from the annotated design model. Experience shows that CSM is also necessary for cleaning and auditing the design information, and providing default interpretations in case it is incomplete, before creating a performance model.","PeriodicalId":235512,"journal":{"name":"Workshop on Software and Performance","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128500567","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
