    We focus on distributed simulation based on local time warp deployed over several sites connected through an interconnection network (a loosely coupled domain). We propose and study a mechanism to tune elaboration according to varying communication performances, to reduce resource consumption and rollback costs that result from unpredictable network behavior. The mechanism is composed of two parts... View full abstract»

  • An approach for stream retrieval over HLA-RTI in distributed virtual environments

    Publication Year: 2000, Page(s):103 - 109

    The HLA-RTI provides a general-purpose network communication mechanism for distributed virtual environments (DVE), but it does not support stream transmission and control directly. This paper illustrates a presentational audio-video continuous-media retrieval application over RTI, which is an extension to our previous paper “An approach for stream transmission over HLA-RTI in distributed vir...

    We examine various modeling and simulation applications of cluster computing using a Beowulf cluster. These applications are used to investigate the performance of our cluster in terms of computational speedup, scalability, and communications. The applications include solution of linear systems by Jacobi iteration, distributed image generation, and the finite difference time domain solution of Max... View full abstract»

  • WATIS2: design and application of an environment simulation system for test improvement of control software for automatic logistic systems

    Publication Year: 2000, Page(s):5 - 12
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (564 KB)

    Control computer systems for automatic logistic systems contain reactive modules, which are usually tested on-site, in conjunction with the real environment. This leads to high test costs and unsatisfactory test coverage. Environment simulation models offer an execution environment for customizable, in-house testing. The architecture and process model of WATIS2, a flexible, efficient an... View full abstract»

    This paper describes the implementation of RTI-Kit, a modular software package to realize runtime infrastructure (RTI) software for distributed simulations such as those for the High Level Architecture. RTI-Kit software spans a wide variety of computing platforms, ranging from tightly coupled machines such as shared memory multiprocessors and cluster computers to distributed workstations connected...

    Supply-chain management covers the planning and management of material and information from the manufacturer through the distributors, and finally to the customer. With the globalization of markets, the optimization of supply-chain management becomes more and more important. Simulation of supply-chains can help in the optimization process by evaluating the impact of alternative policies. To suppor... View full abstract»

    Data distribution management (DDM) is one of the services defined by the DoD High Level Architecture. DDM is necessary to provide efficient, scalable mechanisms for distributing state updates and interaction information in large scale distributed simulations. We describe data distribution management mechanisms (also known as filtering) used for real time training simulations. We propose a new DDM ... View full abstract»

    The problem of network bandwidth limitations is encountered in almost any distributed virtual environment or networked game. In a typical client-server setup, where the virtual world is managed by a server and replicated by connected clients which visualize the scene, the server must repeatedly transmit update messages to the clients. By employing visibility information, the number of messages tra... View full abstract»

    This paper describes the addition of an extra piece of software, a rollback manager to implement state saving and rollback management for optimistic federates in the High Level Architecture (HLA). This mechanism uses computational reflection techniques to create a rollback manager metaobject that extends the low-level time management services provided by HLA. The main propose of the rollback manag... View full abstract»

    One of the services provided by the High Level Architecture (HLA) Run-Time Infrastructure (RTI) is data distribution management (DDM), which aims to make data communication more efficient by sending data to only those federates requiring the data. Several DDM methods, notably region and grid-based, have been proposed and some of them have been implemented in RTI. We first briefly discuss grid-base... View full abstract»

    This paper describes a time warp mechanism designed to exploit temporal uncertainty (TU) in distributed simulation. Novel in the proposed approach are: a formal event model where events are assigned time intervals instead of usual punctual timestamps; an aggressive cancellation technique which shifts overheads from communications to computation; and an implementation in Java which deploys a framew...
