高性能计算机曙光4000A的网格使能特征

网格计算的理想是实现基于Internet的资源共享和协同工作，是Internel．继WWW后的又一个发展浪潮．高性能计算机(超级服务器)是网格中主要的共享资源提供者，而网格也必将成为高性能计算机的主要应用环境．因此网格成为推动高性能计算机发展的一个重要因素，高性能计算机研制中必须考虑网格的需求，并提供必要的支持．曙光4000A是由中国科学院计算技术研究所最新研制的面向网格的高性能计算机，该系统的研制得到国家“八六三”高技术研究发展计划的支持，并作为中国国家网格的主节点部署在上海超级计算中心．详细论述了曙光4000A系统中主要的网格使能特征，这些特征从体系结构、系统硬件和软件方面对网格提供了支持，是从高性能计算机研制角度对网格使能技术进行的积极探索和尝试．

Grid-Enabling Features of the Dawning 4000A High-Performance Computer

The objectives of grid computing are resource sharing and cooperative working over Internet.Grid is the next wave of Internet after WWW.High-performance computers are main resource providers for sharing, and grid will become the main application environment of high-performance computers.So grid is a key factor for pushing high-performance computers' development ahead.The development of high-performance computers must take the requirements of grid into account, and provide essential supports.Dawning 4000A is a high-performance computer developed by the Institute of Computing Technology, the Chinese Academy of Sciences.It is funded by the 863 National High-Tech Program, and has been installed at Shanghai Supercomputing Center as a key node of Chinese National Grid.In this paper, grid-enabling features of the Dawning 4000A system are described in detail.These features provide supports for grid computing in different aspects, including computer architecture, system hardware, and software.Dawning 4000A has made progress in grid-enabling technologies used in high-performance computers.
