Title
"Performance Evaluation of Complex Systems: from Large Software Architectures to the Cell Processor"


Abstract

While developing complex systems such as large software artifacts, it is important to ensure that the system satisfies its functional and non-functional requirements; in particular, the system must provide an appropriate level of performance. In this talk we show how performance modeling techniques can be applied during the early stages of the software development process, helping the software architect to analyze multiple design alternatives. The proposed technique is quite general, and has been applied also to the evaluation of Web Service workflows. Finally, we introduce how the same approach can be further extended to the performance analysis of applications running on the Cell Broadband Engine, a recently developed processor with an interesting (alghough quite complex) internal structure.
