摘　　要：根据气象应用网格的特点和影响负载均衡的因素,对基于气象应用网格的负载均衡技术进行分析和探讨,提出一种气象应用网格中的负载均衡算法,实验结果表明该算法提高网格的负载能力。With the successful development of CMAG,the shared tremendous calculation and information resources in China meteorological board will come true recently,thus,!the information isolated island on CMAG will be disappeared and the utilization will be increased.The urgent problem is how to solve the imbalance of the server node load and the low performance responding ability of server cluster within CMAG.At present,several kinds of schemes of technology have been put forward so as to improve the load balance and the response performance of each node,while load-balanced technology is a new one.This paper tries to analyze the load-balanced technology in CMAG,based on the features in CMAG and the disturbed factors of the load balance,and improved genetic load-balanced algorithms in CMAG has been put forward,too.The result illustrates that the algorithm can obviously improve the load-balanced capability.
