Pluggable grid services

Abstract

This paper introduces a new concept of pluggable grill service, that provides seamless access to computational grids, based on aspect-oriented techniques. Pluggable grid services avoid explicit calls to grid services in scientific codes, localize grid-specific concerns into well defined modules and can be (un)plugged from scientific codes. Domain specific code becomes oblivious of grid issues, allowing scientists to concentrate on domain specific issues, and to manage grid issues by composing grid-specific modules. This paper presents a collection of pluggable grid services that illustrates the idea and shows how pluggable grid services can grid-enable a skeleton framework.
