Research And Realization Of Monitoring And Trigger System In Store Grid Environment

The Grid has become the third popular technologic wave after the traditional internet and web. It is called the third generation application of internet. Actually Grid computing has emerged as a new important technology upon the internet. It is orientated to coordinated resource sharing in dynamic and multi-institutional virtual organizations.In this paper,we introduce some basic knowledge of Grid computing,such as what Grid is.And the important component in Globus Project are:Grid Security infrastructure(GSI),Globus Resource Allocation Manager (GRAM),especially the Monitoring and Discovery Service (MDS)in Globus Project.Resource monitoring and trigger is the base of the Campus Store Grid since it will offer the necessary resource information to other grid middleware.The power of resource monitoring and trigger system will strongly and directly affect the degree of the grid usage efficiency.Based on the research of grid,the attentive problems are brought forward.This paper introduced the basic principle and also related techniques and methods of resource monitoring and trigger.Based on the characteristics of campus store grid,there is a discussion about important functions of campus store grid which should be realized and,analysis of the position of the resource monitoring and discovery service in the store grid.Fanally,the services of campus store grid's resource monitoring and trigger have been realized.
