A problem solving environment based on grid services: NAREGI-PSE

Abstract

The National Research Grid Initiative (NAREGI) program is trying to develop NAREGI-PSE, which is a part of the NAREGI middleware. It provides services for deploying and executing large scale scientific computer simulation software on a grid's distributed and heterogeneous computer system. NAREGI-PSE has a PSE server that handles the applications residing on the distributed computers, and co-shares the application know-how, such as the source codes shared by the research community. This PSE server consists of an application pool and four PSE services. Users access the distributed computers through the NAREGI portal and the NAREGI application environment, which includes the NAREGI-PSE. The PSE server's main purposes are: (1) simple and easy execution of a user's application program in the grid environment, (2) simple and easy deployment of a user's program onto the distributed computer environment, (3) simple and easy software plug-in system into the application pool in the PSE server for software-reuse, and (4) application archive for a co-sharing application and it's know-how among the research communities, which is achieved by grid virtual organization (VO). NAREGI middleware is designed and developed based on grid services according to OGSA/WSRF frameworks. © 2007 International Federation for Information Processing.
