Tests of PoD with ATLAS Prodsys2 and first experience with HTTP Federation / Di Nardo, Roberto (INFN Laboratori Nazionali di Frascati) ; Vilucchi, Elisabetta (INFN Laboratori Nazionali di Frascati) ; Ganis, Gerardo (European Laboratory for Particle Physics, CERN) ; Antonelli, Mario (INFN Laboratori Nazionali di Frascati)
During the LHC Run-1, Grid resources in ATLAS have been managed by the PanDA and DQ2 systems. In order to meet the needs for the LHC Run-2, Prodsys2 and Rucio are used as the new ATLAS Workload and Data Management systems [...]

Development of a Next Generation Concurrent Framework for the ATLAS Experiment / Leggett, Charles (Lawrence Berkeley National Laboratory and University of California, Berkeley) ; Calafiura, Paolo (Lawrence Berkeley National Laboratory and University of California, Berkeley) ; Lampl, Walter (University of Arizona) ; Malon, David (Argonne National Laboratory) ; Stewart, Graeme (University of Glasgow, SUPA - School of Physics and Astronomy) ; Wynne, Benjamin (University of Edinburgh)
The ATLAS experiment has successfully used its Gaudi/Athena software framework for data taking and analysis during the first LHC run, with billions of events successfully processed. However, the design of Gaudi/Athena dates from early 2000 and the software and the physics code has been written using a single threaded, serial design. [...]

In this presentation we will review the ATLAS Monte Carlo production setup including the different production steps involved in full and fast detector simulation. A report on the Monte Carlo production campaigns during Run-I, Long Shutdown 1 (LS1) and status of the production for Run-2 will be presented. [...]

Scalable and fail-safe deployment of the ATLAS Distributed Data Management system Rucio / Lassnig, Mario (European Laboratory for Particle Physics, CERN) ; Vigne, Ralph (Institut fuer Astro- und Teilchenphysik der Leopold-Franzens-Universitaet Innsbruck) ; Barisits, Martin-Stefan (European Laboratory for Particle Physics, CERN) ; Beermann, Thomas Alfons (Bergische Universitaet (Wuppertal), Fachbereich Mathematik und Naturwissenschaften) ; Serfon, Cedric (European Laboratory for Particle Physics, CERN) ; Garonne, Vincent (University of Oslo)
This contribution details the deployment of Rucio, the ATLAS Distributed Data Management system. The main complication is that Rucio interacts with a wide variety of external services, and connects globally distributed data centres under different technological and administrative control, at an unprecedented data volume.

Resource control in ATLAS distributed data management: Rucio Accounting and Quotas / Barisits, Martin-Stefan (European Laboratory for Particle Physics, CERN)
The ATLAS Distributed Data Management system stores more than 160PB of physics data across more than 130 sites globally. Rucio, the next-generation data management system of ATLAS has been introduced to cope with the anticipated workload of the coming decade. [...]

Monitoring and controlling ATLAS data management: The Rucio web user interface / Lassnig, Mario (European Laboratory for Particle Physics, CERN) ; Beermann, Thomas Alfons (Bergische Universitaet (Wuppertal), Fachbereich Mathematik und Naturwissenschaften) ; Barisits, Martin-Stefan (European Laboratory for Particle Physics, CERN) ; Serfon, Cedric (European Laboratory for Particle Physics, CERN) ; Vigne, Ralph (Institut fuer Astro- und Teilchenphysik der Leopold-Franzens-Universitaet Innsbruck) ; Garonne, Vincent (University of Oslo)
The monitoring and controlling interfaces of the previous data management system DQ2 followed the evolutionary requirements and needs of the ATLAS collaboration. The new system, Rucio, has put in place a redesigned web-based interface based upon the lessons learnt from DQ2, and the increased volume of managed information. [...]

Designing a future Conditions Database based on LHC experience / Formica, Andrea (Commissariat a l'Energie Atomique (CEA), DSM/IRFU, Centre d'Etudes de Saclay) ; Barberis, Dario (INFN Genova and Universita' di Genova, Dipartimento di Fisica) ; Gallas, Elizabeth (Department of Physics, Oxford University) ; Govi, Giacomo (Fermi National Accelerator Lab. (US)) ; Lehmann Miotto, Giovanna (European Laboratory for Particle Physics, CERN) ; Pfeiffer, Andreas (CERN)
The ATLAS and CMS Conditions Database infrastructures have served each of the respective experiments well through LHC Run 1, providing efficient access to a wide variety of conditions information needed in online data taking and offline processing and analysis. During the long shutdown between Run 1 and Run 2, we have taken various measures to improve our systems for Run 2. [...]

Integration of PanDA workload management system with Titan supercomputer at OLCF / Panitkin, Sergey (Brookhaven National Laboratory (BNL)) ; De, Kaushik (The University of Texas at Arlington) ; Klimentov, Alexei (Brookhaven National Laboratory (BNL)) ; Oleynik, Danila (Joint Institute for Nuclear Research) ; Petrosyan, Artem (Joint Institute for Nuclear Research) ; Schovancova, Jaroslava (The University of Texas at Arlington) ; Vaniachine, Alexandre (Argonne National Laboratory) ; Wenaus, Torre (Brookhaven National Laboratory (BNL))
The PanDA (Production and Distributed Analysis) workload management system (WMS) was developed to meet the scale and complexity of LHC distributed computing for the ATLAS experiment. While PanDA currently uses more than 100,000 cores at well over 100 Grid sites with a peak performance of 0.3 petaFLOPS, next LHC data taking run will require more resources than Grid computing can possibly provide.
