Abstract
Many kinds of resources in large and distributed environment related puting
environment are required by distributed simulation, and management of these resources is a
complex task, which can be plished bining 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 puting change the point-to-munication 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 putation.
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.
