关于网格及其它分布计算技术的若干问题的讨论

1.引言在“网格:面向虚拟组织的资源共享技术”一文中,我们主要给出了由Ian Foster等定义的网格及相关基本概念和研究领域,讨论了网格的基本理念和关键技术。在“网格体系结构详解”一文中,详述了Globus项目提出的网格体系结构的构成及功能。这些内容旨在说明网格是什么。实际上,我们也可以从另一方面,或不同的角度来观察和认识网格。比

Discussion of Serval Issues for Gird and other Distributed Computing Technologies

Grid computing is a new field which distinguished from conventional distributed computing by its focus on large-scale virtual organizations resources sharing. This paper presents discussion of serval issues for Grid technologies and other contemporary distributed computing technologies. First,we introduce enterprise computing technologies in brief, including CORBA, DCOM, Java, Enterprise JavaBeans and J2EE ,and discuss how Grid technologies related to them. Next,we introduce an Internet-based parallel computing technology named Javelin. Other distrbuted computing technologies and how them related to Grid technologies are discussed. Finaly, we discuss the need of inter-grid protocols to enable interoperability among different Grid systems,and serval other perspectives on Grids are also disscused.
