Prototype a knowledge discovery infrastructure by implementing Relational Grid Monitoring Architecture (R-GMA) on European Data Grid (EDG)

This paper describes the implementation of a ScanOnce algorithm in SQL for quick association rule mining and the development of a data mining infrastructure JetGrid. The architecture of JetGrid is designed to be compatible with lower-level grid mechanisms since it is to operate on top of Relational Grid Monitoring Architecture (R-GMA) provided by European Data Grid (EDG). JetGrid for quick knowledge discovery was preliminarily prototyped and it is extensible, using an object-oriented design that was coded in C++. Mining agents will be staged to one or more computing elements on the EDG. They will mine data delivered using GridFTP and/or Globus transport mechanism. Some initial experimental results are presented, which provide some indication of the performance of the JetGrid data mining infrastructure on top of EDG.
