The Large Hadron Collider at CERN will start data acquisition in 2007. The A Torioidal LHC ApparatuS (ATLAS) experiment is preparing for the data handling and analysis via a series of data challenges and production exercises to validate its computing model to provide useful samples of data for detector and physics studies. The ATLAS production system has been successfully used to run production of simulation data at an unprecedented scale. Up to 10 000 jobs were processed by the system on about 100 sites in one day. In this paper, we discuss the experience of performing analysis jobs using this system on the LCG infrastructure
