網格計算被廣泛的應用，透過不同的虛擬組織整合了許多分散式的資源來達到高效能的計算，有別以往的單一網格環境，所可利用的資源受限於其虛擬組織的規膜大小而有限，在本論文當中，我們提出一個多重的網格新架構，於本研究當中於多重網格環境之上層，建置一個資源代理人的平台，整合了來自於不同虛擬組織的單一網格環境，形成一個更寵大的計算資源，打破不同虛擬組織之間的限制，讓所屬於不同網格當中的計算資源可以被更有效的利用，避免不必要的資源浪費。另外，提出一個跨網格環境的資源配置策略，讓資源代理人在分配工作置整個多重網格環境時，達到較佳的資源分配，避免受到網路壅塞的關係而降低效能。 Grid computing is now in widespread use, which integrates geographical computing resources across multiple virtual organizations to achieve high performance computing. A single grid often not provide a huge resource, because virtual organizations have no the adequate of computing resources restriction on the scale of organizations. In this thesis, we present a new grid architecture, which integrates multiple computational grids, named Multi-Grid, from different virtual organizations. We build a resource broker on multiple grid environments, which integrates a number of single grids from different virtual organizations without the limited of organizations. We can efficiently use the multiple grid resource avoid waste of resource. In addition, we proposed a Multi Grid Resource Selection Strategy for the resource broker to select the better allocation of resource before submitting job avoid network congestion caused of decrease of performance.
