Distributed analysis challenges in ATLAS — Günter Duckeck, •Federica Legger, Christoph Anton Mitterer und Rodney Walker — Ludwig-Maximilians-Universität München
The ATLAS computing model has undergone massive changes to meet the high luminosity challenge of the second run of the Large Hadron Collider (LHC) at CERN. The production system and distributed data management have been redesigned, a new data format and event model for analysis have been introduced, and common reduction and derivation frameworks have been developed. We report on the impact these changes have on the distributed analysis system, study the various patterns of grid usage for user analysis, focusing on the differences between the first and the second LHC runs, and measure performances of user jobs.
