面向对象的元计算系统的单一映象空间模型研究

随着计算机网络技术的成熟，基于网络的高性能计算技术正趋向异构节点间的元计算技术方向发展。元计算系统的研究目标是：将地理上分布的、属于不同管理域的、运行不同软件的、异构的计算和存储资源以及昂贵的仪器设备通过高速网络连接起来,形成超级计算能力。支持元计算的、将异构计算节点连接起来、实现系统透明访问的技术，是元系统的研究重点。本文论述了一种基于树型结构的单一映象空间模型－SiSM，它屏蔽构节点的硬件边界，为用户提供统一的编程接口、透明访问的虚拟机器。

A OBJECT-ORIENTED SINGLE-IMAGE SPACE MODEL FOR METASYSTEM

Along with the maturity of computer network technology, the high performance computing based on network is evolving into metacomputing for heterogeneous system. A metasystem is composed geographically distributed resources (includes hosts, database, and peripheral devices, etc.) that can be reached over the network. Metacomputing give user the illusion that the files, database, computers, and external devices they can reach over a network consistute one giant transparent computational enviroment. It is very important that metacomuting collect heterogeneous hosts into a single, coherent virtual machine, giving the user the power of a unified enviroment. In this paper, a object-oriented single-image space model(SiSM) that likes a tree is described, it mask the hardware boundary, giving the user the uniform program interface and a coherent virtual machine.
