    This paper presents a hierarchical composite synchronization algorithm for parallel discrete-event simulation. The composite approach combines an asynchronous CMB-style channel scanning method with a synchronous window-based method to avoid pathological situations where neither synchronization algorithms would perform optimally. The hierarchical approach addresses the discrepancy in the communicat... View full abstract»

    Due to diverse network latencies, participants in a Distributed Virtual Environment (DVE) may observe different inconsistency levels of the simulated virtual world, which can seriously affect fair competition among them. In this paper, we investigate how to disseminate Dead Reckoning (DR)-based updates with the objectives of achieving fairness among participants and reducing inconsistency as much ...

    Developing complex technical systems requires a systematic exploration of the given design space in order to identify optimal system configurations. However, studying the effects and interactions of even a small number of system parameters often requires an extensive number of simulation runs. This in turn results in excessive runtime demands which severely hamper thorough design space exploration... View full abstract»

    Time Warp synchronized parallel discrete event simulators are organized to operate asynchronously and aggressively without explicit synchronization between the concurrently executing simulators. In place of an explicit synchronization mechanism, the concurrent simulators maintain a common virtual clock model and implement a rollback/recovery mechanism to restore causal order when out-of-order even...

  • A New Approach to Zero-Copy Message Passing with Reversible Memory Allocation in Multi-core Architectures

    Publication Year: 2012, Page(s):44 - 52
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (300 KB) | HTML iconHTML

    We present a new Zero-Copy approach for message passing in a tightly coupled, multi - process parallel discrete event simulation. Our approach is highly scalable and is suited for large scale distributed simulations. A Zero-Copy approach never copies message content. Rather, messages are created initially in a shared - memory region, and only a smart pointer referring to the shared memory object i... View full abstract»

    The emergence of many core architectures with shifting balance between computation and communication overhead can have a tremendous impact on performance and scalability of fine-grained parallel applications such as PDES. It may also be necessary to rethink the design philosophy of key PDES subsystems, that were traditionally focussed on hiding long communication delays. In this paper, we perform ...

    As a distributed simulation standard, the high level architecture (HLA) is used to facilitate the interoperability and reuse of multiple federates, rarely applied in the high-performance parallel simulation. This paper, however, shows a parallel simulation running on a 10 teraflops cluster system, which is based on the master-slave programming model, developed in the use of runtime infrastructure ...

    To develop antisubmarine searching decision-making system, discrete event system simulation is researched with applications. Based on force turning event generation, the search progress is divided into sequential linear spaces, and analytic equations are established for find event generation. Simulation experiment for large number of specimens is implemented with parallel computing, and efficiency... View full abstract»

    The cloud computing paradigm attracts increasing amount of Modeling&Simulation (M&S) practitioners to perform their simulations in the cloud. Two issues, namely, the architecture of the Cloud-based Simulation (CSim) and the parallel simulation job scheduling in the CSim, should be addressed ï¬rst to make the CSim practical. This paper reports our recent work on the two issue... View full abstract»

  • SafeBTW: A Scalable Optimistic Yet Non-risky Synchronization Algorithm

    A new optimistic synchronization algorithm for Parallel Discrete Event Simulation (PDES) called Safe BTW is proposed in this paper. This new algorithm eliminates risky event processing in the Time Warp processing stage of the original BTW algorithm and is founded on a concept called "safe causal relation". In our new algorithm, the length of any chained rollback operations is limited to at most on... View full abstract»

    Aimed to reduce the overheads using the Time Management (TM) in HLA based distributed simulations, the TM based on publish-subscribe topology information is investigated. The condition under which the message may be received before its causal predecessor is firstly analyzed. And then, the TM algorithms using vector clock are put forward, in which the condition is judged before the clock is compari... View full abstract»

  • A Bug Locating Method for the Debugging of Parallel Discrete Event Simulation

    Debugging is critically important for diagnosing bugs of programs. In optimistic Parallel Discrete Event Simulation(PDES), a bug is probably not to be reproduced for the different orders of event processing in different simulation runs, so locating bugs is of great challenge in debugging PDES programs. To solve this problem, we first propose a bug reproducing method based on checkpoint/restart mec... View full abstract»

    The line of sight (LOS) queries often consume a significant fraction of system resources in military simulation. The high time complexity of LOS computation not only limit the amount of entities in the simulation, but also hamper the CPU from doing more urgent and important tasks. To overcome this problem, we utilize graphic process units (GPU) to accelerate the LOS computation at two levels, sing... View full abstract»

    The distributed simulation is popular in both commercial and academic M&S. One of the main challenges faced by large-scale use is a speedy information transmission(IT) technology, where traditional ones such as unicast, broadcast and mul-ticast may not suitable for large scale applications because of the lack of transmission control. In this paper, we present a content based IT technology via ... View full abstract»
