Center node: "static analysis of run time errors in embedded real time parallel c programs"
  Abstract: We present a static analysis by Abstract Interpretation to check for run-time#N#errors in parallel and multi-threaded C programs. Following our work on#N#Astr\'ee, we focus on embedded critical programs without recursion nor dynamic#N#memory allocation, but extend the analysis to a static set of threads#N#communicating implicitly through a shared memory and explicitly using a finite#N#set of mutual exclusion locks, and scheduled according to a real-time#N#scheduling policy and fixed priorities. Our method is thread-modular. It is#N#based on a slightly modified non-parallel analysis that, when analyzing a#N#thread, applies and enriches an abstract set of thread interferences. An#N#iterator then re-analyzes each thread in turn until interferences stabilize. We#N#prove the soundness of our method with respect to the sequential consistency#N#semantics, but also with respect to a reasonable weakly consistent memory#N#semantics. We also show how to take into account mutual exclusion and thread#N#priorities through a partitioning over an abstraction of the scheduler state.#N#We present preliminary experimental results analyzing an industrial program#N#with our prototype, Th\'es\'ee, and demonstrate the scalability of our#N#approach.
