In this paper we introduce a new concept, network atomic operations (NAOs) to create a zero-cost consistent cut. Using NAOs, we define a wall-clock-time driven GVT algorithm called Seven O'Clock that is an extension of Fujimoto's shared memory GVT algorithm. Using this new GVT algorithm, we report good optimistic parallel performance on a cluster of state-of-the-art Itanium-II quad processor systems for both benchmark applications such as PHOLD and real-world applications such as a large-scale TCP/Internet model. In some cases, super-linear speedup is observed.
