How To Review 4 Million Lines of ATLAS Code / Stewart, Graeme (University of Glasgow, SUPA - School of Physics and Astronomy) ; Lampl, Walter (University of Arizona) /ATLAS Collaboration
As the ATLAS Experiment prepares to move to a multi-threaded framework (AthenaMT) for Run3, we are faced with the problem of how to migrate 4 million lines of C++ source code. This code has been written over the past 15 years and has often been adapted, re-written or extended to the changing requirements and circumstances of LHC data taking. [...]

The Rucio Consistency Service / Serfon, Cedric (University of Oslo) ; Garonne, Vincent (University of Oslo) /ATLAS Collaboration
One of the biggest challenge with Large scale data management system is to ensure the consistency between the global file catalog and what is physically on all storage elements. To tackle this issue, the Rucio software which is used by the ATLAS Distributed Data Management system has been extended to automatically handle lost or unregistered files (aka Dark Data). [...]

ATLAS Distributed Computing experience and performance during the LHC Run-2 / Filipcic, Andrej (Jozef Stefan Institute (SI)) /ATLAS Collaboration
ATLAS Distributed Computing during LHC Run-1 was challenged by steadily increasing computing, storage and network requirements. In addition, the complexity of processing task workflows and their associated data management requirements led to a new paradigm in the ATLAS computing model for Run-2, accompanied by extensive evolution and redesign of the workflow and data management systems.

The ATLAS production system has provided the infrastructure to process of tens of thousand of events during LHC Run1 and the first years of the LHC Run2 using grid, clouds and high performance computing. We address in this contribution several strategies and improvements added to the production system to optimize its performance to get the maximum efficiency of available resources from operational perspective and focusing in detail in the recent developments
