【摘要】 基于网格体系结构节点资源能够被共享并被协同使用的概念,设计在分布式节点上实现数据存储和传递的网格数据存储系统。该系统允许网格用户在本地将数据上传到网格,网格管理节点负责对参与共享存储资源的节点进行管理,并将预定大小的数据分配到相应节点存储,同时响应网格用户的请求,使用基于Hash表的路由信息,找到对应请求网格数据的最佳路径,并激活网格线程,实现网格数据在节点间的完整传递。基于Alchemi网格中间件和.NET框架对遥感数据而进行的开发和应用表明,桌面网格动态存储是一个可行的网格计算应用。更多还原

【Abstract】 Designed a dynamically grid data storage system on distributed nodes for data storage and transmission based on the concept that the node resources can be shared and coordinated.The system allowed the grid user upload the local data to the grid,the grid manager node is responsible for the management of the nodes and its shared storage resources,it scheduled the predefined size data to the corre-sponding data storage node and in response to the request of the grid user to search the best path of the grid node which has stored data with the Hash label,by wake-up the grid thread to accomplish the grid data transmission.A application that exercise this theory is de-veloped using the Alchemi grid computing middleware based on.NET framework to the remote sensing data,and show that the desktop grid dynamic storage model is a feasible grid computing application.更多还原
