Optimization of ATLAS computing resource usage through a modern HEP Benchmark Suite via HammerCloud and PanDA / Szczepanek, Natalia Diana (CERN) ; Giordano, Domenico (CERN) ; Di Girolamo, Alessandro (CERN) ; Glushkov, Ivan (Brookhaven National Laboratory (US)) ; Menendez Borge, Gonzalo ; Lory, Alexander (Ludwig Maximilians Universitat (DE)) ; Vukotic, Ilija (University of Chicago (US)) /ATLAS Collaboration
In April 2023 HEPScore23, the new benchmark based on HEP specific applications, was adopted by WLCG, replacing HEP-SPEC06. As part of the transition to the new benchmark, the CPU core power published by the sites needed to be compared with the effective power observed while running ATLAS workloads. [...]

The fight against COVID-19: Running Folding@Home simulations on ATLAS resources / South, David (Deutsches Elektronen-Synchrotron (DE)) ; Forti, Alessandra (University of Manchester (GB)) ; Glushkov, Ivan (University of Texas at Arlington (US)) ; Heinrich, Lukas Alexander (CERN) ; Lassnig, Mario (CERN) ; Walker, Rodney (Ludwig Maximilians Universitat (DE)) /ATLAS Collaboration
Following the outbreak of the COVID-19 pandemic, the ATLAS experiment considered how it could most efficiently contribute using its distributed computing resources. After considering many suggestions, examining several potential projects and following the advice of the CERN COVID Task Force, it was decided to engage in the Folding@Home initiative, which provides payloads that perform protein folding simulations.

Implementation of ATLAS Distributed Computing monitoring dashboards using InfluxDB and Grafana / Beermann, Thomas Alfons (Bergische Universitaet Wuppertal) ; Alekseev, Aleksandr (M.V.Lomonosov Moscow State University) ; Barberis, Dario (INFN Genova and Universita' di Genova, Dipartimento di Fisica) ; Crépé-Renaudin, Sabine (Laboratoire de Physique Subatomique et de Cosmologie de Grenoble (LPSC)) ; Elmsheuser, Johannes (Brookhaven National Laboratory (BNL)) ; Glushkov, Ivan (The University of Texas at Arlington) ; Svatos, Michal (Institute of Physics of the Czech Academy of Sciences) ; Vartapetian, Armen (The University of Texas at Arlington) ; Vokac, Petr (Czech Technical University in Prague) ; Wolters, Helmut (Laboratorio de Instrumenta\c{c}\~ao e Fisica Experimental de Particulas - LIP, Lisbon) /ATLAS Collaboration
For the last 10 years, the ATLAS Distributed Computing project has based its monitoring infrastructure on a set of custom designed dashboards provided by CERN-IT. This system functioned very well for LHC Runs 1 and 2, but its maintenance has progressively become more difficult and the conditions for Run 3, starting in 2021, will be even more demanding; hence a more standard code base and more automatic operations are needed.
