Parallelization is an efficient approach to accelerate multi-core, multi-processor and cluster architecture simulators. Nevertheless, frequent synchronization can significantly hinder the performance of a parallel simulator. A common practice in alleviating synchronization cost is to relax synchronization using lengthened synchronous steps. However, as a side effect, simulation accuracy deteriorates...
A common practice for reducing synchronization overheads in parallel simulation of a large-scale cluster is to relax synchronization with lengthened synchronous steps. However, as a side effect, simulation accuracy degrades considerably. This paper proposes a novel mechanism that keeps the running speeds of different nodes consistent by synchronizing logical clocks with the wall clock periodically...
