ART - ATLAS Release Tester using the Grid / Cuhadar Donszelmann, Tulay (University of California, Irvine) ; Lampl, Walter (University of Arizona) ; Stewart, Graeme (European Laboratory for Particle Physics, CERN) /ATLAS Collaboration
The ART system is designed to run test jobs on the Grid after an ATLAS nightly release has been built. The choice was taken to exploit the Grid as a backend as it offers a huge resource pool, suitable for a deep set of integration tests, and running the tests could be delegated to the highly scalable ATLAS production system (PanDA).

Deployment of containers on the diverse ATLAS infrastructure / Forti, Alessandra (School of Physics and Astronomy, University of Manchester) /ATLAS Collaboration
We will describe the deployment of containers on the ATLAS infrastructure. There are several ways to run containers: as part of the batch system infrastructure, as part of the pilot, or called directly. [...]

Enabling ATLAS big data processing on Piz Daint at CSCS / Sciacca, Francesco Giovanni (University of Bern, Albert Einstein Center for Fundamental Physics, Laboratory for High Energy Physics) ; Weber, Michele (University of Bern, Albert Einstein Center for Fundamental Physics, Laboratory for High Energy Physics) /ATLAS Collaboration
Predictions for requirements for the LHC computing for Run 3 and Run 4 (HL_LHC) over the course of the next 10 years show a considerable gap between required and available resources, assuming budgets will globally remain flat at best. This will require some radical changes to the computing models for the data processing of the LHC experiments. [...]

Multithreaded simulation for ATLAS: challenges and validation strategy / Bandieramonte, Marilena (University of Pittsburgh) ; Chapman, John Derek (Cavendish Laboratory, University of Cambridge) ; Gray, Heather (Lawrence Berkeley National Laboratory and University of California, Berkeley) ; Muskinja, Miha (Lawrence Berkeley National Laboratory and University of California, Berkeley) ; Chiu, Yu Him Justin (University of Victoria) /ATLAS Collaboration
Estimations of the CPU resources that will be needed to produce simulated data for the future runs of the ATLAS experiment at the LHC indicate a compelling need to speed-up the process to reduce the computational time required. While different fast simulation projects are ongoing (FastCaloSim, FastChain, etc.), full Geant4 based simulation will still be heavily used and is expected to consume the biggest portion of the total estimated processing time.

The ATLAS EventIndex for LHC Run 3 / ATLAS Collaboration
The ATLAS Event Index was designed in 2012-2013 to provide a global event catalogue and limited event-level metadata for ATLAS analysis groups and users during LHC Run 2 (2015-2018). It provides a good and reliable service for the initial use cases (mainly event picking) and several additional ones, such as production consistency checks, duplicate event detection and measurements of the overlaps of trigger chains and derivation datasets.

Computing Activities at the Spanish Tier-1 and Tier-2s for the ATLAS experiment towards the LHC Run3 and High Luminosity (HL-LHC periods) / ATLAS Collaboration
The ATLAS Spanish Tier-1 and Tier-2s have more than 15 years of experience in the deployment and development of LHC computing components and their successful operations. The sites are already actively participating in, and even coordinating, emerging R&D; computing activities developing the new computing models needed in the LHC Run3 and HL-LHC periods. [...]

Using Graph Databases / Hrivnac, Julius (LAL, Univ. Paris-Sud, IN2P3/CNRS, Universite Paris-Saclay) /ATLAS Collaboration
Data in HEP are usually stored in tuples (tables), trees, nested tuples (trees of tuples) or relational (SQL-like) databases, with or without a defined schema. But many of our data have a graph structure without a schema, or with a weakly imposed schema. [...]

The ATLAS Hardware Track Trigger design towards first prototypes / Dittmeier, Sebastian Johannes (Physikalisches Institut) ; ATLAS TDAQ Collaboration /ATLAS Collaboration
In the High Luminosity LHC, planned to start with Run4 in 2026, the ATLAS experiment will be equipped with the Hardware Track Trigger (HTT) system, a dedicated hardware system able to reconstruct tracks in the silicon detectors with short latency. This HTT will be composed of about 700 ATCA boards, based on new technologies available on the market, like high speed links and powerful FPGAs, as well as custom-designed Associative Memories ASIC (AM), which are an evolution of those used extensively in previous experiments and in the ATLAS Fast Tracker (FTK).

Upgrade of the ATLAS MDT Readout and Trigger for the HL-LHC / ATLAS MDT Collaboration /ATLAS Collaboration
The luminosity increase of the LHC in Phase-II calls for an in-depth redesign of the entire MDT readout chain. While the high rate of primary detector signals requires increased bandwidth at each level of the data path, the MDT readout must, in addition, supply accurate coordinate information to the trigger system, leading to more reliable identification of high-pT tracks.
