    Modeling & Simulation practitioners use Commercial-off-the-shelf Simulation Packages to model process-based system problems in a wide range of domains. Technological limitations of these packages restrict what practitioners can model in terms of simulation run times and system boundaries. Experiences in dealing these problems with Grid Computing and Distributed Simulation are presented and a r... View full abstract»

    Stochastic Modeling & Simulation require very good random sources which have now been available for more than a decade. However the parallelization of random streams remains delicate for many practitioners. Recent experience shows that a misuse of pseudo-random number parallelization techniques is not infrequent in various simulation domains. This talk will present the state of the art in the ...

  • Parallel Discrete Event N-Body Dynamics

    Publication Year: 2011, Page(s):1 - 10
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (364 KB) | HTML iconHTML

    Numerical simulation of gravitational N-body systems is an important tool for studying the dynamic behaviour of stellar systems, and in some cases is the only option available given the extremely large time scales involved. The direct summation approach, which evaluates the force between each pair of particles at each time step, produces the most accurate results. However despite many algorithmic ...

    Exascale supercomputers will have millions or even hundreds of millions of processing cores and the potential for nearly billion-way parallelism. Exascale compute and data storage architectures will be critically dependent on the interconnection network. The most popular interconnection network for current and future supercomputer systems is the torus (e.g., k-ary, n-cube). This paper focuses on t... View full abstract»

    Interest Management (IM) aims at eliminating irrelevant state updates transmitted in Networked Virtual Environment (NVE). The traditional IM mechanisms can be classified into area-based and cell-based mechanisms. Hybrid IM mechanism was proposed recently to reduce the communication overhead by utilizing the cell-based mechanism to reduce Area-Of-Interest (AOI) updates in the area-based mechanism. ...

    Maintaining a consistent presentation of the virtual world among participants is a fundamental problem in the Distributed Virtual Environment (DVE). The problem is exacerbated due to the limited network bandwidth and errorprone transmission. This paper investigates Dead Reckoning (DR) update scheduling to improve consistency in the DVE against message loss. Using the metric of Time-Space Inconsist... View full abstract»

    We consider a class of models describing generic agents (e.g. macromolecules, small organisms) which are able to travel in space, can sense the surrounding environment, and can react accordingly. In these models, we focus on individual-based simulation. We start with defining a simple centralized simulation algorithm, which we then improve so to develop a distributed algorithm producing the same o... View full abstract»

  • Framework for Simulation of Hybrid Systems: Interoperation of Discrete Event and Continuous Simulators Using HLA/RTI

    A hybrid system is a combination of discrete event and continuous systems that act together to perform a function not possible with any one of the individual system types alone. A simulation model for the system consists of two sub-models, a continuous system model, and a discrete event model, and interfaces between them. Naturally, the modeling/simulation tool/environment of each sub- model may b... View full abstract»

  • An Analysis of the Cost of Validating Semantic Composability

    Publication Year: 2011, Page(s):1 - 8
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (236 KB) | HTML iconHTML

    Validation of semantic composability is a non-trivial problem and a key step in component-based modeling and simulation. Recent work in semantic composability validation promise to reduce verification, validation, and accreditation efforts. However, the underlying cost of current validation approaches can undermine the promised benefits, and the trade-off between validation accuracy and validation... View full abstract»

    Model reuse is a promising and appealing convention for effective development of simulation systems. However it poses daunting challenges to various issues in research such as Reusability and Composability in model integration. Various methodological advances in this area have given rise to the development of different component reusability frameworks such as BOM (Base Object Model). However, lack... View full abstract»

    Manufacturing systems can be thought as production networks nodes whose relations have a strong impact on design and analysis of each system. One of the most common techniques to support these tasks is Discrete-Event Simulation. The state-of-the art commercial simulators are already adopted to analyze complex networked systems, but the development of a monolithic simulation model can be too comple... View full abstract»

    Coupling and synchronized execution of legacy simulation models is a complex task. Simulation experts need knowledge in the domains of distributed simulation and HLA to conduct such complex simulation projects. This is one reason for insufficient acceptance of distributed simulation in industrial areas. To increase the number of distributed simulation projects in industrial domains, a dedicated ac...

    Automatic generation of simulation models has been a recurring topic in scientific papers for years. A common problem of all known model generation approaches is the generation of dynamic behavior, e.g. buffering or control strategies. This paper introduces a novel methodology for generation of dynamic behavior, based on artificial neural networks, which is usable directly in the simulation. We al... View full abstract»

    Simulation and emulation are commonly used to study the behavior of communication networks, owing to the cost and complexity of exploring new ideas on actual networks. Emula-tions executing real code have high functional fidelity, but may not have high temporal fidelity because virtual machines usually use their host's clock. A host serializes the execution of multiple virtual machines, and time-s... View full abstract»

    Virtual machine (VM)-based simulation is a method used by network simulators to incorporate realistic application behaviors by executing actual VMs as high-fidelity surrogates for simulated end-hosts. A critical requirement in such a method is the simulation time-ordered scheduling and execution of the VMs. Prior approaches such as time dilation are less efficient due to the high degree of multipl...

    The performance estimation of Wireless Sensor Networks (WSNs) is recommended before large scale deployment as the cost of redesign after the event could be expensive. This paper presents a novel wireless channel model, which exposes WSN applications such as environmental data gathering to realistic conditions, such as non-isotropic radiation, unreliable and asymmetric links, and the effect of buil...
