With the information expanding and network popularization, the way that accessing single database can not satisfy the demands for users. The requirement to access distributed database is increased. This paper firstly implemented distributed database query with the grid computing architecture Alchemi which is based on .NET. Then, a distributed database searching system model was constructed by grid...
Grid computing architecture was defined to be a complete physical layer. The message transfer in network must be in secure. In this study, we propose the encryption algorithm in every grid node to keep information in security. Sender requests key code from receiver grid node, uses this key code to encrypt message to produce cipher text and sends out. Receiver also uses this key code to decrypt cipher...
Grid computing architecture was defined to be a complete physical layer. The functions of information systems based on grid architecture are resources sharing, collaborative processing, etc. System performance is calculated from resource usages of all grid nodes. If we have load-balancing in all grid nodes, we will have good performance in the system. All the grid nodes are divided to supervisor,...
Grid computing architecture was defined to be a complete physical layer. Data transfer in network must be in secure. In this study, encryption and decryption algorithms of a site authentication and its message are developed and applied in each grid node to ensure secure transmitted information. If the site information has been built in supervisor node then it can receive data sent from other grid...
With the recent success in transmitting the first beam through Large Hadron Collider (LHC), generation of vast amount of data from experiments would soon follow in the near future. The data generated that will need to be processed will be enormous, averaging 15 petabytes per year which will be analyzed and processed by one- to two-hundred-thousand jobs per day. These jobs must be scheduled, processed...
In this paper, we proposed a load balancing digital right management platform based on grid computing (GC-DRM) and compliance of grid portal standards by using porlet. The platform integrates Globus Toolkit 4 and Condor 6.9.2 and uses Web 2.0 to construct the Web-based user interface for providing job submission, control, management, monitor and DRM services. It provides six categories of services,...
Artykuł opisuje architekturę Grid Computing w oparciu o technologię sieci Peer-to-Peer. Przybliża różnice koncepcyjne budowy tych sieci oraz ich wykorzystanie. Prezentowana jest koncepcja realizacji sieci grid przy uwzględnieniu Podejścia Stosowego do obiektowych baz danych. Sformułowana jest koncepcja fizycznej architektury sieci grid, a także logicznej budowy poszczególnych maszyn tworzących taką...
