"Information Extraction from Real-time Applications at Run Time"

Friday February 03, 2012 11:00 AM
Location: 3211, EB2 NCSU Centennial Campus
(Visitor parking instructions)

This talk is part of the System Research Seminar series

 

Abstract:

Modern systems with their millions of lines of code are beyond deep comprehension of any developer. Often developers use program tracing  and profiling to extract information, which helps them to understand  the system's behaviour. Often monitors are then also deployed in the  final system to check the proper functioning of the system at run  time.  Code instrumentation is a common method for extracting information  from running programs. Current instrumentation methods are  inapplicable for real-time applications, because these methods'  current theory and practice concentrate on preserving logical  correctness only. Real-time applications, however, must also meet  timing requirements and thus instrumentation and, more generally,  information extraction mechanisms must also preserve such properties.  This talk first introduces the general problem of using software-based  mechanisms for information extraction, and then discusses two  approaches applicable to real-time systems: time-aware instrumentation  and time-triggered runtime verification. 

 

Short Bio:

Sebastian Fischmeister is currently Assistant Professor in the Department of Electrical and Computer Engineering at the University of Waterloo, Canada. He received his MASc in Computer Science at the Vienna University of Technology, Austria, and his Ph.D. degree at the University of Salzburg, Austria. He was awarded the APART stipend in 2005 and worked as a research associate at the University of Pennsylvania, USA, until 2008.  

He performs systems research at the intersection of software technology, distributed systems, and formal methods. His preferred application areas are distributed real-time embedded systems in the domain of automotive systems, avionics, and medical devices. He is now working on the theory and application of state-based schedules for adaptive systems and a monitoring/debugging/tracing framework for time-sensitive systems.
