校園資料網格平台建置與應用

Abstract

近年來隨著電腦科技與軟體的快速發展，帶給人類很大的方便及利益。然而，面對如此龐大的資料量，我們該如何有效率的處理大量的資料，並且讓資料進而達到資源共享的目標，乃此研究的核心部分。我們透過資料網格(Data Grid)運算技術以及Storage Resource Broker (SRB)平台來管理與分享資源，此平台可以將分散於世界各地的資源，經由MCAT伺服器的管理，邏輯上如同儲存於同一實體位址，使用者可以透過不同的存取介面，如同網頁、視窗、或指令的介面，去登入SRB平台，進而存取與分享在平台上的資源。SRB的優勢是它達到可跨越不同作業系統平台，我們可以在Windows的作業系統上，進行管理Linux系統上的資料。並且，可以連結不同資料庫來取得所需的資料。讓我們達到方便管理大量資料的目標。

In recent years, fast developments in computer, network and software technologies have brought large number of conveniences and benefits. One of major challenges in parallel with this development is how to manage huge amount of material stored across internet, as also alternatives to handle these data fast and sharing resources at the same time. In this paper, we explore the use of data grid technique and software Storage Resource Broker (SRB) [2, 3, 4] to build up a data grid platform, in order to manage and share these resources. This platform gathers and shares all information belonging to a particular group of users through MCAT server. Users can access all information of the SRB datagrid platform through a number of ways, such as websites, GUI’s, or text line commands. One of major feature datagrid platforms built using SRB software is the availability to work in different operating systems; one administrator can manage the system using Linux, while information is retrieved by users using Windows operating system. In addition, a number of datagrid platforms can be interconnected and exchanging information. We have built a datagrid platform inside Providence University, where the goal is to provide a fast and reliable data exchange platform among faculties and researchers inside campus with high efficiency. In future, alternative utilizations of this platform are going to be proposed, as e-learning, acceleration of complex calculations, among others.
