ATLAS Distributed Data Management

Special requirements other than the set up mentioned in the CfA text.



The ATLAS Experiment, one of the four detectors taking data from the Large Hadron Collider, will generate multi-Petabyte data volumes that need to be distributed worldwide over more than 100 computing sites. For this reason, ATLAS has developed the DQ2 distributed data management system on top of the services delivered by the WLCG Grid infrastructure. The DQ2 software is responsible for handling discovery, replication and deletion of ATLAS data as well as providing the necessary accounting and management of user and group quotas.
In this paper we will focus on the accounting service describing its components and showing different application examples taken from the monitoring interfaces.
