    As an alternative to spatial parallelization of simulation models, time-parallel simulation offers the potential for massive parallelism with a high level of independence between the parallel processes. Unfortunately, due to inherent problems, the applicability of time-parallel simulation is restricted. Therefore, it has been proposed recently, to use approximation with time-parallel simulation in... View full abstract»

    Neural systems are composed of a large number of highly-connected neurons and are widely simulated within the neurological community. In this paper, we examine the application of parallel discrete event simulation techniques to networks of a complex model called the Hodgkin-Huxley neuron. We describe the conversion of this model into an event-driven simulation, a technique that offers the potentia... View full abstract»

    Efficient computer simulation of complex physical phenomena has long been challenging due to their multi-physics and multi-scale nature. In contrast to traditional time-stepped execution methods, we describe an approach using optimistic parallel discrete event simulation (PDES) and reverse computation techniques. We show that reverse computation-based optimistic parallel execution can significantl... View full abstract»

    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 syste... View full abstract»

    Parallelising sequential discrete event simulation programs is often a tedious process, with no guarantee for speedup. This paper describes a performance analyser tool developed to predict the execution performance of parallel discrete event simulation programs, using either optimistic or conservative protocols. The tool aims to provide the user with the flexibility of choosing the simulation prot... View full abstract»

    A novel micro-kernel approach to building parallel/distributed simulation systems is presented. Using this approach, a unified system architecture is developed for incorporating multiple types of simulation processes. The processes hold potential to employ a variety of synchronization mechanisms, and could even alter their choice of mechanism dynamically. Supported mechanisms include traditional l...

    Internet worm spread is a phenomenon involving millions of hosts, who interact in complex and diverse environment. Scanning speed of each infected host depends on its resources and the defenses at work in its network. Aggressive worms further interact with the underlying Internet topology - the dynamics of the spread is constrained by the limited bandwidth of network links, and high-volume scan tr...

    For worms with known signatures, properly configured firewalls can prevent infection of a network from the outside. However, as several recent worms have shown, portable computers provide worms with an entry point into such networks, since these computers are connected behind the firewall. Once inside, the firewall provides no protection against the worm's further spread. Wireless networks are par... View full abstract»

    The threat of Internet worms has been, and continues to be, one of the most important issues faced by networking researchers and network users. The need for accurate and efficient modeling and analysis methods cannot be understated. Models that accurately reflect the behavior of existing and yet-to-be deployed worms is critical to understanding how to deal with this ongoing threat. Recently develo... View full abstract»

    Simulation of large-scale networks requires enormous amounts of memory and processing time. One way of speeding up these simulations is to distribute the model over a number of connected workstations. However, this introduces inefficiencies caused by the need for synchronization and message passing between machines. In distributed network simulation, one of the factors affecting message passing ov... View full abstract»

    Scalable and efficient network simulation methods are the method of choice for evaluating and verifying wireless network protocols on a moderate to large scale. This need becomes obvious when simulating very large-scale wireless networks such as emerging ad hoc sensor networks in which the number of nodes can be the order of thousands or more, and with very high node density. Unfortunately, simula... View full abstract»

    Simulation of large-scale networks demands that we model some flows at coarser time-scales than others, simply to keep the execution cost manageable. This paper studies a method for periodically computing traffic at a time-scale larger than that typically used for detailed packet simulations. Applications of this technique include computation of background flows (against which detailed foreground ... View full abstract»

    A fundamental requirement for any network simulation environment is the realistic forwarding of packets from a source to a destination in the simulated topology. The routing decisions at each hop along the path should accurately represent decisions made by actual routers with a similar topology. Further, the routing decisions must be affected by topology changes, such as link weight adjustments or... View full abstract»
