MCRTsim: A simulation tool for multi-core real-time systems

This paper presents an open source task scheduling simulator, called MCRTsim, for real-time systems with uniprocessors, multiprocessors, and multi-core processors. It contains a task set generator, a set of real-time schedulers and synchronization protocols, and a comprehensive set of tools including visualized execution tracer, schedulability analyzer, and measurement and statistic modules. Therefore, we can easy to evaluate the performance of existing scheduling algorithms as well as synchronization protocols by using MCRTsim. Furthermore, MCRTsim also contains a Java class library for supporting the design of new scheduling and synchronization protocols with minimum efforts. Another key feature of MCRTsim is the supporting of DVFS-enabled processors so that the capabilities of energy-aware scheduling algorithms and synchronization protocols can be better understand.
