Talk Title: Back to the Future: Can We Get There In Time?

Abstract: Performance evaluation techniques have been successfully applied to computer software and hardware systems for many years. In recent years, however, there has been a decline in the number of people and organizations applying these techniques to the computer systems that need them. Nevertheless, researchers in performance evaluation continue to contribute significant new techniques and tools that advance the state of the art. We examine factors that have led to this disparity and some strategies and techniques for significantly improving the situation.

Short Biography: Dr. Connie U. Smith, a principal consultant of the Performance Engineering Services Division of L&S Computer Technology, Inc., is known for her work in defining the field of Software Performance Engineering (SPE) and integrating SPE into the development of new software systems. Dr. Smith received the Computer Measurement Group's prestigious AA Michelson Award for technical excellence and professional contributions for her SPE work. She also authored the original SPE book: Performance Engineering of Software Systems, published in 1990 by Addison-Wesley, and approximately 100 scientific papers. She is the creator of the SPE-ED™ performance engineering tool. She has over 25 years of experience in the practice, teaching, research and development of the SPE performance prediction techniques.

Talk Title: Analysis of Large Systems with Mean Field and Markovian Agents

Abstract: The necessity of studying sensor networks, rich internet applications, social networks and molecular biology have raised the need of being able to consider systems composed by very large population of similar objects. This lead to the development of new modelling paradigms, such as Fluid Process Algebra, Mean Field analysis and Markovian Agents. These methodologies produces exact results if the number of considered objects goes to the infinity, but provide reasonable approximations even for finite quantities. In this work Mean Field analysis and Markovian Agents models will be presented.

Short Biography: Dr. Marco Gribaudo has been a Senior Researcher (Assistant Professor) in Computer Science and the University of Turin since 2005. Since gaining his PhD in 2002 on a "Hybrid Formalism for Performance Evaluation", he has published widely in areas such as fluid performance analysis and product form analysis in GSPNs. He has a track record in applying theoretical performance techniques to practical applications such as peer-to-peer networks and mobile phone data networks. He has published approximately 70 journal and conference papers in the field of performance analysis and engineering.
