The Research Of HLA Distributed Simulation Framework Based On Grid And Resource Scheduling Algorithm

High Level Architecture(HLA)is a new type of distributed simulation framework to meet the demand of the large-scale complex simulation system.With the high-speed development of science,technology and large data,the required computing power of the large-scale simulation task is higher and higher.A single computer or computer clusters cannot satisfy the required computing power,therefore,the grid technology is introduced into the HLA distributed interactive simulation(DIS)which is the hotspot to solve the problem.The article introduces the grid technology into the HLA which can achieve that using the network can joint all kinds of heterogeneous computers,data resources,server resources and so on together,which dispersed in different regions,and form a kind of high-performance grid computing environment and large virtual computer environment,to meet the increasing the demand of the large simulation system.It can realize the resource sharing,collaborative problems solving.The HLA distributed simulation based on grid technology is a combination of a new generation of technology products,and is now one of the effective ways to improve the distributed simulation system.The system can be solved the deficiencies in the aspects of management and resource allocation.In the simulation system,the resource-task scheduling Algorithm performance directly affects the efficiency of simulation system,and is one of the key factors to improve system efficiency.The simulation system is not only to make the task of the total execution time to reduce as far as possible,and to consider the grid load balancing problem between simulation system resources.In this paper,on the basis of the open grid services architecture,we design a HLA distributed simulation framework based on grid.Under the premise of this run framework,we study the distributed simulation resource scheduling management algorithms based on grid,and analyze the resource scheduling management model.And On the basis of Min-Min algorithm and Max-Min algorithm,the matching-rate function of resource and task is put forward to solve the problem of unbalanced load of Min-Min algorithm.In combination with system load balance parameters,an improved algorithm based on matching-rate function is proposed.Finally,the improved algorithm is tested,and the experimental data shows that the improved algorithm has a certain improvement in the time dimension and economic dimension,and achieves the realization of the aim of load balancing.
