摘　　要：在科学、工程和商业领域,仍然有些问题,由于它们的规模和复杂性,当代的超级计算机并不能有效地处理。实际上,这些问题经常要求的资源往往是变化多样的,不能从单个机器来获得。许多人已经对地理上分散的计算机的资源联接起来做了许多实验研究,这种新的研究方法就是网格。本文介绍了网格的历史发展,讨论了网格的特征、系统结构、功能、需求,并与其他系统进行了比较。另外,还列出了目前国外的一些网格项目,探讨了网格未来可能的发展方向。In the fields of science,engineering and business,there are still problems which can not be dealt effectively with the current generation of supercomputers because of the size and complexity of these problems.In fact,these problem ofen require a variety of heterogeneous resources that are not available from a single machine.Many people have conducted experimental studies on the cooperative use of geographically distributed resources conceived as a single powerful computer.This new approach is named by grid.This paper introduces the history of grid,discusses its features,architectures,function and requirement,compares it with other systems.In addition,a number of items in foreign are listed,the future possible trends are discussed at last.
