SOFTWARE ENGINEERING AND MULTICORE HARDWARE
Presenter: Ugo Buy, Associate Professor, Department of Computer Science University of Illinois at Chicago
Recent onset of multicore processing units requires software developers to design and code their programs as concurrent systems in order to take advantage of hardware performance. However, the development of reliable concurrent systems is notoriously difficult because of the possibility of undesirable situations as deadlocks, data races, livelocks and violations of mutual exclusion constraints. Concurrent systems seldom exhibit deterministic behavior, which further complicates testing and debugging.
This talk will first briefly survey existing methods for coping with the challenges inherent in concurrent system development, such as automatic program verification and parallelizing compilation. Next, we will focus on methods based on supervisory control. In short, a control supervisor is a software component that prevents erroneous behaviors in the original system (aka the controlled system) by disabling computations that could lead to such behaviors. Supervisor synthesis is based on suitable models of the controlled systems, such as Petri nets or finite state automata. Promising empirical results on deadlock prevention in large databases shared by multiple applications will be reported. Additional empirical results will demonstrate the potential performance gains that can be obtained on multicore hardware. This research is partly sponsored by the Security and Software Engineering Research Center (S2ERC), an NSF-sponsored Industrial/University Collaborative Research Center.
About the Presenter
Professor Ugo Buy obtained his PhD degree in Computer Science from the University of Massachusetts at Amherst in 1990. His research in software engineering has an emphasis on formal modeling and analysis of concurrent and real-time software. He has been involved in various federally-sponsored projects seeking to define techniques and tools for formal verification of these systems, using a variety of program representations, such as finite-state automata and Petri nets. In recent years, his research has focused on supervisory control and dynamic reconfiguration of discrete event systems. The controllers must enforce traditional safety and timing properties of the controlled systems. Application to software correctness is under active investigation.
