Top quarks in ATLAS: bridging measurements and searches / Majewski, Stephanie (University of Oregon)
An overview of how top precision measurements (top cross-sections, spin correlations) and top quark production (ttH, SUSY stop, vector-like quarks) are used in ATLAS to search for and constrain new physics..

Integrating Network Awareness in ATLAS Distributed Computing Using the ANSE Project / Klimentov, Alexei (Brookhaven National Laboratory (BNL)) ; De, Kaushik (The University of Texas at Arlington) ; Petrosyan, Artem (Joint Institute for Nuclear Research) ; Batista, Jorge Horacio (University of Michigan, Department of Physics) ; Mc Kee, Shawn Patrick (University of Michigan, Department of Physics)
A crucial contributor to the success of the massively scaled global computing system that delivers the analysis needs of the LHC experiments is the networking infrastructure upon which the system is built. The experiments have been able to exploit excellent high-bandwidth networking in adapting their computing models for the most efficient utilization of resources. [...]

A Validation System for the Complex Event Processing Directives of the ATLAS Shifter Assistant Tool / Anders, Gabriel (European Laboratory for Particle Physics, CERN) ; Avolio, Giuseppe (European Laboratory for Particle Physics, CERN) ; Kazarov, Andrei (Petersburg Nuclear Physics Institute) ; Lehmann Miotto, Giovanna (European Laboratory for Particle Physics, CERN) ; Santos, Alejandro (Universidad National de La Plata (UNLP)) ; Soloviev, Igor (University of California, Irvine)
Complex Event Processing (CEP) is a methodology that combines data from different sources in order to identify events or patterns that need particular attention. It has gained a lot of momentum in the computing world in the past few years and is used in ATLAS to continuously monitor the behaviour of the data acquisition system, to trigger corrective actions and to guide the experiment’s operators.

A New Petabyte-scale Data Derivation Framework for ATLAS / Catmore, James (University of Oslo)
During the Long shutdown of the LHC, the ATLAS collaboration overhauled its analysis model based on experience gained during Run 1. A significant component of the model is a "Derivation Framework" that takes the Petabyte-scale AOD output from ATLAS reconstruction and produces samples, typically Terabytes in size, targeted at specific analyses. [...]

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. [...]
