Simulation of Real-Time Multiprocessor Scheduling Using DES

The evaluation of the numerous real-time scheduling algorithms is difficult without a real and complex implementation. Simulation allows to study the schedulers with more flexibility. This paper presents a simulation tool that uses a process-based discrete-event simulation engine. Compared to the other scheduling simulators, it is able to take into account the impact of the caches through statistical models and direct overheads such as context switches and scheduling decisions. The last Section shows how this tool can be used on concrete examples.
