The Research And Implement Of A Grid System Based On Web

Network is computer,which is the essential concept of Grid.The Grid has been the third popular technologic wave after traditional internet and web. It is so called the third generation application of internet. Actually,Grid computing has emerged as a new important technology upon the internet.It is orientated to be coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations.This thesis has summarily analyzed the background of Grid research,the present situation of research and development,and the development tendency.Aimed at situation of the present Grid technology and combining the web technology,we construct a Grid system based on Web.The thesis illustrates in detail the system's theory basis,design thought,function characteristic and so on.And after studying Grid system's request,key technology and architecture,we put forward a kind of new Grid system.The Grid system describes how to carry on the management to the resource in the whole Grid , how to schedule and run users' jobs,and security and mistakes- allowance technology related to that.Moreover,the system adopts the job submission and the job monitor based on web.And we put forward the hierarchical thought of resource management and global scheduling in the system.The Grid system discussed by the thesis consists of four parts:Grid Client Infor-mation Server, Grid Resource Broker and Grid Service.Because of adopting more advanced technology in the four part ,this system has three characteristics: the usage convenience, mistakes- allowance, security .And it has more profound meaning to the Grid research of today.
