Abstract

The main contribution of this paper is accurate analysis of real-time performance for dynamic real-time applications. A wrong system performance analysis can lead to a catastrophe in a dynamic real-time system. In addition, real-time performance guarantee combined with efficient resource utilization is observed by experiments, while the previous worst-case approaches primarily focused on performance guarantee but resulted in typically poor utilization. The subsequent contribution is schedulability analysis for a feasible allocation of resource management on the Solaris operating system. This is accomplished with a mathematical model and by accurate response time prediction for a periodic, dynamic distributed real-time application.
