Advancements in the ATLAS Fast Chain for HL-LHC: Towards Efficient MC Production / Tsai, Fang-Ying (Stony Brook University (US)) /ATLAS Collaboration
The ATLAS Fast Chain represents a significant advancement in streamlining Monte Carlo (MC) production efficiency, specifically for the High-Luminosity Large Hadron Collider (HL-LHC). This project aims to simplify the production of Analysis Object Data (AODs) and potentially Derived Analysis Object Data (DAODs) from generated events with a single transform, facilitating rapid reproduction of the entire MC dataset multiple times per year.

Fatras integration for ATLAS fast simulation at HL-LHC / Mijovic, Liza (The University of Edinburgh (GB)) ; Wang, Rui (Argonne National Laboratory (US)) ; Javurkova, Martina (University of Massachusetts (US)) ; Chapman, John Derek (University of Cambridge (GB)) ; Shemyakin, Dmitry (Weizmann Institute of Science (IL)) /ATLAS Collaboration
The computing challenges in collecting, storing, reconstructing, and analyzing the colossal volume of data produced by the ATLAS experiment and producing similar numbers of simulated Monte Carlo (MC) events put formidable requirements on the computing resources of the ATLAS collaboration. ATLAS currently expends around 40% of its CPU resources on detector simulation, in which half of the events are produced with full simulation using GEANT4. [...]

The ATLAS Fast Monte Carlo Production Chain Project / Jansky, Roland Wolfgang (Institut fuer Astro- und Teilchenphysik der Leopold-Franzens-Universitaet Innsbruck)
During the last years ATLAS has successfully deployed a new integrated simulation framework (ISF) which allows a flexible mixture of full and fast detector simulation techniques within the processing of one event. With the ISF, the simulation execution speed could be increased up to a factor 100, which makes subsequent digitisation and reconstruction processing the dominant contributions to the MC production CPU cost.

Boosting CPU Efficiency in ATLAS Inner Detector Reconstruction with Track Overlay / Tsai, Fang-Ying (Stony Brook University (US)) ; Duda, Dominik (The University of Edinburgh (GB)) ; Jiggins, Stephen (Deutsches Elektronen-Synchrotron (DE)) /ATLAS Collaboration
In response to the rising CPU consumption and storage demands, as we enter a new phase in particle physics with the High-Luminosity Large Hadron Collider (HL-LHC), our efforts are centered around enhancing the CPU processing efficiency of reconstruction within the ATLAS inner detector. The track overlay approach involves pre-reconstructing pileup tracks and subsequently running reconstruction exclusively on hard-scatter tracks. [...]
