1引言网格的思想,早在1960年就提出来了,但是大规模的研究只是近10年的事。近年来由于不同领域复杂科学计算与海量信息服务的要求,使得计算机必须不断地提高其运算速度和存储容量,同时由于互联网的迅速发展,网上信息资源愈来愈庞大、分散,因此,人们迫切需要数据处理能力更强大的计算机,而超级计算机的价格显然阻止了它进入普通人的工作领域。于是,人们寻找一种造价低廉而数据处理能力超强的计算模式——Grid Computing(网格计算)。
1 INTRODUCTION The idea of grid was proposed as early as 1960, but large-scale research is only a matter of nearly 10 years. In recent years, due to the requirements of complex scientific computing and massive information services in different fields, computers have to constantly improve their computing speed and storage capacity. At the same time, due to the rapid development of the Internet, online information resources are becoming more and more large and scattered. Therefore, people urgently need Data processing more powerful computers, and the super computer prices have obviously prevented it from entering ordinary people’s work areas. As a result, people are looking for a computational model with low cost and superb data processing - Grid Computing.
