Self-configuring and self-optimizing grid components in the GCM model and their ASSIST implementation

We present the concept of autonomic super-component as a building block for Grid-aware applications. Super-components are parametric, higher-order components exhibiting a well-known parallel behaviour. The proposal of a super-component feature is part of the experience we gained in the implementation of the ASSIST environment, which allows the development of self-configuring and optimising component-based applications following a structured and hierarchical approach. We discuss how such approach to Grid programming influenced the design of the Grid Component Model (GCM).
