Frozen-shower simulation of electromagnetic showers in the ATLAS forward calorimeter / Gasnikova, Ksenia (DESY, Hamburg and Zeuthen) ; Glazov, Alexander (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
Accurate simulation of calorimeter response for high energy electromagnetic particles is essential for the LHC experiments. Detailed simulation of the electromagnetic showers using Geant4 is however very CPU intensive and various fast simulation methods were proposed instead. [...]

ATLAS Simulation using Real Data: Embedding and Overlay / Haas, Andy (Department of Physics, New York University) /ATLAS Collaboration
For some physics processes studied with the ATLAS detector, a more accurate simulation in some respects can be achieved by including real data into simulated events, with substantial potential improvements in the CPU, disk space, and memory usage of the standard simulation configuration, at the cost of significant database and networking challenges. Real proton-proton background events can be overlaid (at the detector digitization output stage) on a simulated hard-scatter process, to account for pileup background (from nearby bunch crossings), cavern background, and detector noise.

Collecting conditions usage metadata to optimize current and future ATLAS software and processing / Barberis, Dario (INFN Genova and Universita' di Genova, Dipartimento di Fisica) ; Formica, Andrea (Commissariat a l'Energie Atomique (CEA), DSM/IRFU, Centre d'Etudes de Saclay) ; Gallas, Elizabeth (Department of Physics, Oxford University) ; Oda, Susumu (Kyushu University) ; Rinaldi, Lorenzo (INFN Bologna and Universita' di Bologna, Dipartimento di Fisica e Astronomia) ; Rybkin, Grigori (LAL, Univ. Paris-Sud, IN2P3/CNRS, Universite Paris-Saclay) ; Verducci, Monica (INFN Roma and Sapienza Universita' di Roma, Dipartimento di Fisica) /ATLAS Collaboration
Conditions data (for example: alignment, calibration, data quality) are used extensively in the processing of real and simulated data in ATLAS. The volume and variety of the conditions data needed by different types of processing are quite diverse, so optimizing its access requires a careful understanding of conditions usage patterns. [...]

Measurement of $J/\psi$ production in 5.02 TeV Pb+Pb collisions with the ATLAS experiment / Lopez Lopez, Jorge Andres (Universidad Tecnica Federico Santa Maria) /ATLAS Collaboration
The in-medium suppression of $J/\psi$ production in heavy-ion collisions, with respect to pp collisions, serves as a sensitive probe for studying the quark gluon plasma. A full assessment of the suppression requires understanding effects present in the hot and dense medium in the Pb+Pb collisions as well as cold nuclear effects in the small p+Pb collision. [...]

Measurement of quarkonia production in 5 TeV proton-proton and heavy-ion collisions with the ATLAS detector / Tapia Araya, Sebastian (Universidad Tecnica Federico Santa Maria) /ATLAS Collaboration
The in-medium suppression of heavy quarkonia production in heavy-ion collisions, with respect to proton-proton collisions, serves as a sensitive probe for studying the QGP. A full assessment of the suppression requires understanding effects present in the hot and dense medium in the A-A collisions as well as cold nuclear effects in the small-sized p+A collision. [...]

ATLAS EventIndex Data Collection Supervisor and Web Interface / Garcia Montoro, Carlos (Instituto de Fisica Corpuscular (IFIC), Centro Mixto Universidad de Valencia - CSIC) ; Fernandez Casani, Alvaro (Instituto de Fisica Corpuscular (IFIC), Centro Mixto Universidad de Valencia - CSIC) ; Sanchez, Javier (Instituto de Fisica Corpuscular (IFIC), Centro Mixto Universidad de Valencia - CSIC) /ATLAS Collaboration
The EventIndex project consists in the development and deployment of a complete catalogue of events for the ATLAS experiment [1][2] at the LHC accelerator at CERN. In 2015 the ATLAS experiment has produced 12 billion real events in 1 million files, and 5 billion simulated events in 8 million files. [...]

Processing of the large amount of data produced by the ATLAS experiment requires fast and reliable access to what we call Auxiliary Data Files (ADF). These files, produced by Combined Performance, Trigger and Physics groups, contain conditions, calibrations, and other derived data used by the ATLAS software. [...]
