The knowledge grid

A reference software architecture for geographically distributed PDKD systems, known as 'Knowledge Grid' is discussed. The architecture is built on top of a computational grid that provides dependable, consistent, and pervasive access to high end computational resources. The Grid uses the basic grid services of distributed knowledge discovery on globally connected computers where each node can be a sequential or a parallel machine. The Grid enables the collaboration of scientists that must mine data stored in different research centers as well as analysts that must use a knowledge management system operating on several data warehouses located in the different company establishments.
