摘要
1引言
近年来,随着计算机和通信技术的高速发展,因特网、Web、网格正在变得越来越普及,包含科技、文化、商业、新闻、娱乐等多种形式和类别的信息系统像雨后春笋般出现,使得信息不仅可在大范围共享,而且还能开展分布计算、并行计算、异构计算、元计算等服务.
It is valuable work to construct computational system by means of network,so that its capacity and power can be enhanced and extended. But there is heterogeneity in common among computational systems. It is main obstacle for computational systems to cooperate well. This paper inquires the sound description of heterogeneity for computational systems,and presents several appoaches on definition of heterogeneity. That is significant to go a step further for hiding or exploring heterogeneity in the future.
