Objectives

Performance models have a central role in the design, capacity planning, and management of computing systems. Models may be used at design-time to support capacity planning of the physical infrastructure and to analyze the effects and trade-offs of different architectural choices, anticipating the discovery of potential bottlenecks which may degrade system performance.
Models may also be used at run-time to assess the compliance of the running system with respect to the design-time model and to measure the real system performance parameters in order to fill the gap between design-time and run-time.
Models at run-time can also assess the compliance of service level agreements and trigger the run-time re-configuration of autonomic systems. The goal of this workshop is to bring together researchers and practitioners, who investigate concepts, models and tools for the run-time management of computing systems to analyze autonomic systems transients and describe their behavior at very fine grained time scales.

Topics include but are not limited to:
  • Run-time monitoring and tools, models parameters estimation
  • Control theory models, system identification methods and tools for autonomic systems
  • Burstiness analyses and system transients modeling
  • QoS management and dynamic reconfiguration of autonomic systems
  • Fault tolerance assurance and availability assessment in evolving run-time systems
Intended audience:
Researchers and practitioners, both from the Academia and from the Industry, working in the areas of performance evaluation, control theory, system identification, and QoS management of autonomic systems.

    Software in the near ubiquitous future will need to cope with variability, as software systems get deployed on an increasingly large diversity of computing platforms and operates in different execution environments. Heterogeneity of the underlying communication and computing infrastructure, mobility inducing changes to the execution environments and therefore changes to the availability of resources and continuously evolving requirements require software systems to be adaptable according to the context changes. Software systems should also be reliable and meet the user's performance requirements and needs. Moreover, due to its pervasiveness, software systems must be dependable. Supporting the validation of these self-adaptive systemes to ensure dependability requires a complete rethinking of the software life cycle. The traditional division among static analysis and dynamic analysis is blurred by the need to validate dynamic systems adaptation. Models play a key role in the validation of dependable systems, dynamic adaptation calls for the use of such models at run time. In this talk I will describe the approach we have undertaken in recent projects to address the challenge of assessing dependability for adaptive software systems.

    Paola Inverardi is a Professor at the Computer Science Department at University of L'Aquila. Her research interests are in the field of the application of formal techniques to the development of software systems. These include software specification and verification of concurrent and distributed systems, deduction systems, and Software Architectures. Current research interests mainly concentrate in the field of software architectures specifically addressing the verification and analysis of software architecture properties, both behavioral and quantitative. On this topics Paola collaborates with several national and international companies. Recently Paola is working also on the design and development of mobile resource aware applications.
