Evaluation of Open Grid Service Architecture (OGSA) for Data-Intensive Applications

Title: Evaluation of Open Grid Service Architecture (OGSA) for Data-Intensive Applications

Research Question: Can the Open Grid Service Architecture (OGSA) be effectively applied to data-intensive applications, particularly in the context of High Energy Physics?

Methodology: The researchers designed and implemented a testbed named 'Beryllium' using several PCs located at CERN and Skobeltsyn Institute of Nuclear Physics. This testbed mimicked a Grid system based on the Globus Toolkit 3.0 (GT3), which is an open source implementation of the Open Grid Service Infrastructure (OGSI). They evaluated the architecture's performance, scalability, and security features in a high-energy physics context.

Results: The evaluation demonstrated that the GT3 architecture, which adheres to the OGSA principles, improved the reliability, flexibility, scalability, and security of the distributed system. The testbed successfully hosted several GT3 services, including the Admin, Logging Management, and Management services. The researchers also evaluated the security services and base services, such as the Managed Job, Index, and Reliable File Transfer services.

Implications: The successful implementation and evaluation of the GT3 architecture in a data-intensive application context suggest that OGSA can be an effective approach for constructing Grid systems. This finding has significant implications for the future development and deployment of Grid technologies in high-energy physics and other data-intensive domains.
