Project Goals

The motivation of this research came from the fact that software flexibility is an important issue during the development fo high performance and real-time applications, reliable systems, distributed systems, and in exploratory computing. Software systems are required to deal with an increasing rate of change in technology and user requirements. Moreover, it is imperative that the scientific community and the industry develop techniques to support seamless integration of highly heterogeneous environments. Component technology has appeared as a solution for these problems. However, there is still little support for managing the interactions between the components. Existing component architectures also lack a good understanding of the nature and magnitude of the interactions between components and a notion of invidual performance of components in a component-based system. This research project seeks to modify the way computer systems support component-based software to accommodate dynamic changes in rapidly evolving environments. By maintaining an explicit representation of the interactions between system and application components, the infrastructure can recognize the need for reconfiguration. In addition, it can know how to carry out this reconfiguration without compromising system stability, performance, and reliability.
