Description

ATLAS Distributed Computing organized 3 teams to support data processing at the Tier-0 facility at CERN, and data reprocessing, data management operations, Monte Carlo simulation production, and physics analysis at the ATLAS computing centers located worldwide. In this paper, we describe how these teams ensure that the ATLAS experiment data is delivered to the ATLAS physicists in a timely manner in the glamorous era of LHC data taking. We describe our experience in improving degraded service performance, and we detail the Distributed Analysis support during the exciting period of the computing model evolution.
