CEGA: A workflow PSE for computational applications

Abstract

The importance of problem solving environment (PSE)s over Grid has been emphasized owing to the heterogeneity and the large volume of resources involved and the complexity of computational applications. This paper proposes a Grid-enabled PSE called as Computing Environment for Grid Applications (CEGA) and discusses how it is evolving to devlelop a computational application in a style of workflow model and incorporates Grid computing services to extend its range of services and handle information for development, deployment, execution and maintenance for an application as well as an application requirement itself. The paper describes the architecture of CEGA and its implementation for development, execution and visualization of an application.
