Crowd simulation requires both rendering visually plausible images and managing the behavior of autonomous agents. Therefore, these applications need an efficient design that allows them to simultaneously handle these two requirements. Although several proposals have focused on the software architectures for these systems, no proposals have focused on the computer systems supporting them.In this paper, we analyze the computer architectures used in the literature to support distributed virtual environments. Also, we propose a distributed computer architecture which is efficient enough to support simulations of thousand of autonomous agents. This proposal consists of a cluster of interconnected computers in order to improve flexibility and robustness, as well as a hierarchical software architecture that efficiently provides consistency. Performance evaluation results show that the trade-off between flexibility and consistency allows to efficiently manage thousands of autonomous agents. Therefore, this network-based system architecture can provide the required scalability for large-scale crowd simulations. 相似文献

分布交互仿真的发展经历了从最早的SimNet到DIS以及目前的HLA等多种体系结构,采用HLA结构是日前分布交互仿真发展的趋势。但是目前还存在许多基于DIS的仿真系统,为了能够利用这些已有的仿真资源,有必要使这些DIS系统能够与基于HLA的分布交互仿真系统相连接。因此需要研究DIS/HLA之间的转换和互联技术。该文分析了几种常用的DIS/HLA转换技术方案,指出对于一个具体的DIS与HLA互联问胚,采用转换器的方案是比较容易实现的,给出了相关的开发思路和程序实现,并对所开发的转换器的延时特性进行了测试。开发和应用表明采用转换器不需要对原有的DIS系统进行修改,具有使用方便且容易实现的特点。 相似文献

In this paper, we describe our efforts to support the modeling and simulation of processes associated with software system acquisition activities. Software acquisition is generally a multi-organization endeavor concerned with the funding, management, engineering, system integration, deployment and long-term support of large software systems. We first describe our approach supporting the modeling and simulation of software acquisition processes using a software process architecture (SPA). We then introduce how we support the distribution, concurrent execution and interoperation of multiple software process simulations using the high-level architecture (HLA) and run-time infrastructure (RTI) to address the complexity of software acquisition process architectures. To illustrate this, we provide examples from the design and prototyping of a Web-based environment that supports the modeling and simulation of acquisition process architectures. This environment thus serves as a new kind of software process test-bed that can demonstrate and support experiments incorporating multiple software process simulation systems that interoperate in a distributed and concurrent manner across a network. 相似文献

ArchSim: A System-Level Parallel Simulation Platform for the Architecture Design of High Performance Computer 总被引:2,自引:0,他引:2 下载免费PDF全文

High performance computer (HPC) is a complex huge system, of which the architecture design meets increasing difficulties and
risks. Traditional methods, such as theoretical analysis, component-level simulation and sequential simulation, are not applicable
to system-level simulations of HPC systems. Even the parallel simulation using large-scale parallel machines also have many
difficulties in scalability, reliability, generality, as well as efficiency. According to the current needs of HPC architecture
design, this paper proposes a system-level parallel simulation platform: ArchSim. We first introduce the architecture of ArchSim
simulation platform which is composed of a global server (GS), local server agents (LSA) and entities. Secondly, we emphasize
some key techniques of ArchSim, including the synchronization protocol, the communication mechanism and the distributed checkpointing/restart
mechanism. We then make a synthesized test of some main performance indices of ArchSim with the phold benchmark and analyze
the extra overhead generated by ArchSim. Finally, based on ArchSim, we construct a parallel event-driven interconnection network
simulator and a system-level simulator for a small scale HPC system with 256 processors. The results of the performance test
and HPC system simulations demonstrate that ArchSim can achieve high speedup ratio and high scalability on parallel host machine
and support system-level simulations for the architecture design of HPC systems. 相似文献

Simulating complex and distributed manufacturing systems is not easy using traditional simulation techniques. Manufacturing environment contains several systems that must interoperate and exchange information. A general software architecture is necessary to make manufacturing systems interrelated. This paper presents an overview of distributed manufacturing simulation as well as of information representation in distributed manufacturing simulation using high level architecture (HLA) and its object model template (OMT). The concept is explained with a scenario which is provided to better address the object class structure, interaction class structure, attribute, parameter and data type tables. 相似文献
