网格中应用程序的运行需要获取一些满足特定条件的网格资源。文章提出了一种网格环境下动态资源的表示方法-矩阵表示法,同时研究了矩阵表示法下的资源的查找和更新的算法。该算法充分考虑了资源属性的动态性,由于矩阵计算不用操作资源的原始数据,从而提高了查找的效率,不仅能够进行精确匹配的查询也能进行范围查询。在路由查询时,只要参考本地信息就可给出准确的路由选择。矩阵表示资源还简化了动态资源的更新过程,使资源信息能够及时接近真实的网格环境。 The operation of the application in the grid requires getting some grid resources that meet certain conditions. This paper presents a matrix representation of dynamic resources in the grid environment - matrix representation, while under the matrix representation of resources to find and update algorithms. The algorithm takes full account of the dynamic nature of the resource attributes. Since the matrix computation does not need to manipulate the original data of the resource, the efficiency of the search is improved, not only the exact matching query but also the range query. In the routing query, as long as the reference to local information can be given accurate routing. The matrix representation of resources also simplifies the process of updating dynamic resources so that the resource information can be timely approached to the real grid environment.
