  • Abstract
    Feasibility analysis of a hard-real-time system refers to the process of determining off-line whether the specified system will meet all deadlines at runtime. For many important (and interesting) task models and scheduling algorithms, feasibility analysis is provably computationally very expensive. A framework is established for speeding up the feasibility analysis of uniprocessor real-time systems by implementing these algorithms on parallel machines. The viability of this framework is validated by developing a parallel algorithm for the feasibility analysis of systems of asynchronous periodic tasks that are to be scheduled using the preemptive earliest deadline first scheduling algorithm, and by implementing and testing the performance of this parallel algorithm
