Awareness requirements for adaptive systems

Vítor E. Silva Souza, Alexei Lapouchnian, William N. Robinson, John Mylopoulos
2011 Proceeding of the 6th international symposium on Software engineering for adaptive and self-managing systems - SEAMS '11  
Recently, there has been a growing interest in self-adaptive systems. Roadmap papers in this area point to feedback loops as a promising way of operationalizing adaptivity in such systems.  ...  In this paper, we define a new type of requirement -called Awareness Requirement -that can refer to other requirements and their success/failures.  ...  It defines a language to specify goals and can be used to compile monitors from the goal specification and evaluate goal fulfillment at runtime.  ...

Performance Contracts: Predicting and Monitoring Grid Application Behavior [chapter]

Fredrik Vraalsen, Ruth A. Aydt, Celso L. Mendes, Daniel A. Reed
2001 Lecture Notes in Computer Science  
Sensors monitor runtime application and system performance, and fuzzy logic decision procedures are used to verify whether the contract commitments are upheld.  ...  In this model, we introduce the notion of application intrinsic behavior to separate the performance effects of the runtime system from the behavior inherent in the application itself.  ...

Clustering for improved system-level functional partitioning

Frank Vahid, Daniel D. Gajski
1995 Proceedings of the 8th international symposium on System synthesis - ISSS '95  
We demonstrate that clustering can be used to merge pieces of functionality before applying other heuristics, resulting in reduced runtimes with little or no loss in quality, and often with improvements  ...  Partitioning of system functionality for implementation among multiple system components, such as among hardware and software components, is becoming an increasingly important topic.  ...  For example, Figure 2 (a) provides a partial specication of a fuzzy-logic controller, and Figure 2 (b) provides a decomposition of the specication into 12 functional objects, which in turn must be assigned  ...
