Agent-Based Query Optimisation in a Grid Environment
Luciano Serafini, Heinz Stockinger, Kurt Stockinger, Floriano Zini · 2012
The next generation experiments in High Energy Physics are the driving force for setting up an International Data Grid at CERN, the European Organization for Nuclear Research. Hundreds of Petabytes of data will be distributed and replicated all over the globe starting from 2005. In order to analyse this massive set of distributed data efficiently, we propose a hierarchical query optimisation architecture based on multi-agent technology. The architecture is optimised for the High Energy Physics community but is representative also for other data intensive scientific applications that use distributed data stores and mass storage systems. Keywords: query optimisation, distributed computing, agent technology 1 Introduction The idea of building an International Data Grid [1,2] at CERN, the European Organization for Nuclear Research, was driven by the needs of the next generation accelerator, the Large Hadron Collider (LHC), which is scheduled to be in operation in 2005. Several Petabyte...
