GRID RESOURCE REGISTRY – ABSTRACT LAYER FOR COMPUTATIONAL RESOURCES

Abstract

The growing number of resources available to researchers in the e-Science domain has openednew possibilities for constructing complex scientific applications while at the same timeintroducing new requirements for tools which assist developers in creating such applications.This paper discusses the problems of rapid application development, the use of distributedresources and a uniform approach to resource registration, discovery and access. It presentsthe Grid Resource Registry, which delivers an abstract layer for computational resources.The Registry is a central place where developers may search for available services and fromwhich the execution engine receives technical specifications of services. The Registry is usedthroughout the lifetime of the e-science application, starting with application design, throughimplementation to execution
