Numerous scheduling algorithms were and still are designed in order to handle multiprocessor architectures, raising new issues due to the complexity of such architectures. Moreover, evaluating them is difficult without a real and complex implementation. Thus, this paper presents a tool that intends to facilitate the study of schedulers by providing an easy way of prototyping. Compared to the other scheduling simulators, this tool takes into account the impact of the caches through statistical models and includes direct overheads such as context switches and scheduling decisions.
