SimSo: A Simulation Tool to Evaluate Real-Time Multiprocessor Scheduling Algorithms

In this paper, we present SimSo, a simulator designed for the comparison and the understanding of real-time scheduling policies. This tool is designed to facilitate the implementation of schedulers in a realistic way. Currently, more than twenty-five scheduling algorithms are available in SimSo. A particular attention is paid to the control of the computation time of the jobs therefore introducing more flexibility, for instance by taking into account cache-related preemption delays. In addition, SimSo offers an easy way to generate the tasksets, to perform simulations and to collect data from the experiments.
