Description
During last few years ATLAS has ran a serie of Data Challenges producing simulated
data used to understand the detector performace. Altogether more than 100 terabytes
of useful data are now spread over few dozens of storage elements on the GRID. With
the emergence of Tier1 centers and constant restructuring of storage elements there
is a need to consolidate the data placement in a more optimal way.
We have organised and exercised the ATLAS wide data consolidation using the ATLAS
distributed data management system (DQ2). Experience with the massive data movement
on the GRID will be reported.
