摘　　要：为提高C4ISR系统处理战场情报的能力,结合海上信息基础设施建设,研究了基于信息栅格的情报分布并行处理问题.提出了一种改进Backfilling算法的分层调度方法,设计了基于信息栅格的信息融合并行处理流程,解决了当单节点计算资源不足时,利用邻近节点空闲资源完成信息处理的问题.实验结果表明该方法对降低大容量情报处理的时延有显著改善.The capability of the C4ISR system in processing the battlefield intelligence, combined with the maritime information infrastructure construction, the intelligence information distributed parallel processing based on the grid is studied. A layered scheduling method of an improved Backfilling algorithm is brought forward, the information fusion and parallel processing flow based on information grid is designed, and the problem is resolved by using the idle resources in the adjacent nodes to process the information when the computing resource of a single node is insufficient. The experimental results show that this method can reduce the delay in processing the large volume of intelligence information.
