Composition of Libraries, Software Parts and Problem Solving Environments

چکیده
We consider the problem of creating very large software systems by composing existing software. As components of this process we consider software library elements, software parts and problem solving systems. These items are briefly defined and their principal characteristics given. We discuss the relationship of these items to objects in object oriented programming. The mechanics of the composition are discussed, the key issues are identified and the trade offs discussed. The principal tradeoff is, of course, programming effort versus execution time efficiency. We consider several examples and conclude that building very large software systems as a set of cooperating, somewhat autonomous, pans is a promising direction for research. * This work is supported in part by the Air Force Office of Scicntific Research under grant 88-0243, and the Strategic Defense Initiative under Aimy Research Office contract DAAL0386-K-01606.

Scalable Scientific Software Libraries and Problem Solving Environments
Software librarie.s provide encapsulated problem solving power and problem solving environments (PSEs) give ordinary users painless access to problem solving power. Thus the structure of libraries and the design of PSEs are inextricably linked. This workshop explored the stateof-the-art in these two areas and their interdependence. A few application areas (e.g., linear algebra) have a rather si...

Portlet-based Grid portals have become a crucial part of the cyberinfrastructure by providing component-based problem solving environments for scientists. Although portals aim to provide user-friendly environments with easy-to-use interfaces, the development of portals and their portlet components are time consuming. We aim to provide reusable components for rapid portlet development. Our appro...
