Abstract:The holistic theory is a useful approach for assessing the schedulability of hard real-time distributed systems. In this paper, an improvement on the holistic algorithm is proposed. Original holistic analysis has been extended to make it more generalized. Some real-time applications are also tested and analyzed based on research background of an hard real-time distributed information processing system. The experimental result illustrates that the worst-case response time of each task generated by new algorithm is more accurate and valid.
