| Many kinds of resources in large and distributed environment related to computing environment are required by distributed simulation, and management of these resources is a complex task, which can be accomplished by combining it with the techniques of grid. In order to solve some problems in current High Level Architecture, such as lack of intelligent and flexible mechanism in managing resource, on the basis of OGSA, this paper designs grid resource management framework serving distributed simulation. According to the run-time features, application layer of HLA is made corresponding transform; the working process between every function modular and these modules is designed in detail. Peer to Peer computing change the point-to-point communication from the client/server architecture to the interconnection of peers. The paper makes use of P2P technology to implement the grid resource administrative system, from which all the central management nodes are removed, and their corresponding function modules are transferred into each simulation node. Thus all the simulation nodes get the power of autonomy computation. System has essential overall node no longer, and generates local temporary management node according to needs for every task. Single-failure problem in distributed simulation system is solved effectively. In this paper, load-measured method and scheduling algorithm to manage simulation computation node is finally designed and implemented. And an experiment is utilized to test the system performance. As a result, show that system can manage simulation resource efficiently and steadily, furthermore has good load balanced property. |
