December, 18th: “React OS” operating system

Bragin Aleksey

Bragin Aleksey

Aleksey Bragin is a president of the “ReactOS” foundation. He was graduated from Bauman MSTU (he got master degree from IU7 department, and finished post-graduate studying).

ReactOS® is an effort to create a Free and Open Source replacement for the Microsoft Windows NT® family that is compatible with both applications and drivers. The NT® architecture has always been highly flexible and powerful and its continued dominance in the computer industry means it is one of the most supported family of operating systems in existence, with its latest iteration being Windows 8.
As these days operating systems are little more than gateways to applications that users want to run, an open source NT implementation would allow users to continue using familiar programs in a familiar environment. The project seeks to embrace the strengths of the NT family while avoiding many of the configuration decisions that made older versions of Windows vulnerable and maintaining a lightweight environment so that a computer’s resources can be dedicated to what really matters to the user, running their applications.

December, 19th: Verification of Concurrent Programs under Relaxed Memory Models (in English)

Roland Meyer

Roland Meyer

Roland Meyer - Juniorprofessor of Theoretical Computer Science, Head of the Concurrency Theory Group (University of Kaiserslautern). Previously, he was a CNRS postdoc in LIAFA, University Paris 7, from March 2009 to June 2010. He worked in the Transregional Research Center AVACS at the University of Oldenburg. In February 2009, he obtained his PhD from the University of Oldenburg, where he was a PhD student in the graduate school TrustSoft. From October 2001 to September 2005, I studied Computer Science and Mathematics in Oldenburg. His research interests are expressiveness, computer-aided verification, and formal languages of concurrent systems. Focus on infinite-state models, in particular reconfigurable networks and relaxed memory models.

Sequential Consistency (SC) is the intuitive shared memory model where operations happen atomically and in the order in which they were issued. Programmers often assume their code runs on SC hardware, an assumption that is no longer valid for modern multiprocessors. For performance reasons, recent hardware only implements relaxed memory models that admit out-of-program-order and non-store atomic executions. Programs that work correctly under SC may show undesirable effects when run on relaxed memory models. With the trend towards multicore machines, bugs due to relaxed memory models become a serious problem in mainstream programming.

In this talk, we provide an overview of recent results on the verification of concurrent programs that run on relaxed memory models. We concentrate on the Total Store Ordering model that is implemented in x86 processors, and discuss the problems of reachability and robustness. Given a concurrent program and a configuration, reachability checks whether the program admits an execution leading to this configuration. Robustness is to decide whether the behaviour of a given program on a relaxed memory model coincides with the expected SC semantics. Both problems have been shown to be decidable, but with very different complexity.
