全球信息栅格中,美军的计算能力主要由国防企业计算中心(DECC)提供。重点介绍了美军DECC的发展现状。在DECC体系结构的基础上,结合集群技术提出一种应用于全球信息栅格的企业级计算中心设计构想,给出了主要的应用技术和体系结构设计方案。使用集群技术构建的计算中心体系结构具有高可用性、可伸缩性和高性能计算的特点,具有重要的实用意义。
In the Global Information Grid, US military computing power is provided mainly by the Defense Business Computing Center (DECC). The paper introduces the development status of US DECC. On the basis of DECC architecture, combined with cluster technology, this paper proposes a design concept of enterprise computing center applied to global information grid, and presents the main application technologies and architecture design. The computing center architecture built using clustering technology has the characteristics of high availability, scalability and high performance computing, which is of great practical significance.
