Metapsi: a web-based metacomputing problem-solving environment for buiding complex applications

The increasing complexity of large distributed scientific applications raises the problem of the coordination of diverse computational resources (computers, data bases, etc.). Multi-disciplinary applications often make use of coupled computational resources that cannot be replicated at a single site. There is the need for smart and user-friendly Problem-Solving Environments (PSE) that free scientists from concerns related to the location and complexity of the computing platform being used.
