"Systematic Testing of Concurrent Programs with CHESS"

(Vortrag im Rahmen der "Distinguished Lecture Series Spring 2008" des Max Planck Instituts für Software-Systeme)

In this talk, I'll present work by Madan Musuvathi and Shaz Qadeer of my group on radically improving how we test multi-threaded concurrent programs. Using ideas from direct model checking of executables, they have created an automated tool called CHESS that systematically explores the thread schedules of a concurrent program. CHESS incorporates several novel algorithms including iterative context bounding, which prioritizes the search to schedules with fewer context switches first, and fair stateless model checking, which guarantees that the tool will correctly handle programs that depend on fair scheduling to terminate and will find all livelocks in finite state programs. I will demonstrate a version of CHESS I have created for .NET programs and talk about our vision for making debugging of concurrent programs a first-class activity supported by all levels of the software stack.
