| Abstract | Abstract. This paper presents a new Global Virtual Time (GVT) algorithm, called TQ-GVT that is at the heart of a new high performance Time Warp simulator designed for large-scale clusters. Starting with a survey of numerous existing GVT algorithms, the paper discusses how other GVT solutions, especially Mattern’s GVT algorithm, influenced the design of TQ-GVT, as well as how it avoided several types of overheads that arise in clusters executing parallel discrete simulations. The algorithm is presented in details, with a proof of its correctness. Its effectiveness is then verified by experimental results obtained on more than 1,000 processors for two applications, one synthetic workload and the other a spiking neuron network simulation. |
