Automatic WCET Analysis of Real-Time Parallel Applications Ozaktas, Haluk Rochange, Christine Sainrat, Pascal WCET analysis parallel programming thread synchronisation Tomorrow's real-time embedded systems will be built upon multicore architectures. This raises two challenges. First, shared resources should be arbitrated in such a way that the WCET of independent threads running concurrently can be computed: in this paper, we assume that timepredictable multicore architectures are available. The second challenge is to develop software that achieves a high level of performance without impairing timing predictability. We investigate parallel software based on the POSIX threads standard and we show how the WCET of a parallel program can be analysed. We report experimental results obtained for typical parallel programs with an extended version of the OTAWA toolset.
