A Dynamic Load Balancing Method for Parallel Simulation of Accuracy Adaptive TLMs

In this paper we present a load balancing method for parallel simulation of accuracy adaptive transaction level models. In contrast to traditional fixed accuracy TLMs, timing accuracy of adaptive TLMs changes during simulation. This makes the computation and synchronization characteristics of the models variable, and practically prohibits the use of static load balancing. To deal with this issue, we present a light-weight load balancing method which takes advantage of, and can be easily incorporated with the simulation time synchronization scheme used in parallel TLM simulation. We have developed a highperformance parallel simulation kernel based on the proposed method, and our experiments using the developed kernel show the effectiveness of the proposed approach in a realistic scenario.
