The Controls and Configuration Software of the ATLAS Data Acquisition System: evolution towards LHC Run 3 / Kazarov, Andrei (speaker) (NRC Kurchatov Institute PNPI (RU))
The ATLAS experiment at the Large Hadron Collider (LHC) op- erated very successfully in the years 2008 to 2018, in two periods identified as Run 1 and Run 2. ATLAS achieved an overall data-taking efficiency of 94%, largely constrained by the irreducible dead-time introduced to accommodate the limitations of the detector read-out electronics. [...]

Symbolism and dynamics of the systems / Gonella, Francesco (speaker) (Università Ca' Foscari Venezia)
Here I introduce the Stock-and-Flow diagrams, that use a symbolic representation taken from energetics. I will show how to draw a comprehensive diagram including only stocks, flows and processes, and how the choice of these sets of elements and of the (spatial and temporal) boundary actually reflects the reason why one wants to study the system at issue [...]

The less known facets of ISOLDE: Beyond Standard Model searches and live science applications / Kowalska, Magdalena (speaker) (CERN)
The ISOLDE laboratory – which uses 50 % of CERN’s proton pulses – is devoted to the production and research using unstable nuclei. Over 1000 different isotopes available at  ISOLDE allow to test extensively the strong interaction in the nuclear medium and thus shed light on the nuclear structure across the nuclear chart [...]

Daisy: Data analysis integrated software system for X-ray experiments / Tian, Haolai (speaker) (Institute of High Energy Physics)
Daisy (Data Analysis Integrated Software System) has been designed for the analysis and visualization of the X-ray experiments. To address an extensive range of Chinese radiation facilities community’s requirements from purely algorithmic problems to scientific computing infrastructure, Daisy sets up a cloud-native platform to support on-site data analysis services with fast feedback and interaction. [...]

A real-time FPGA-based cluster finding algorithm for LHCb silicon pixel detector / Bassi, Giovanni (speaker) (SNS & INFN Pisa (IT))
Starting from the next LHC run, the upgraded LHCb High Level Trigger will process events at the full LHC collision rate (averaging 30 MHz). This challenging goal, tackled using a large and heterogeneous computing farm, can be eased addressing lowest-level, more repetitive tasks at the earliest stages of the data acquisition chain. [...]

Integration and Commissioning of the Software-based Readout System for ATLAS Level-1 Endcap Muon Trigger in Run 3 / Sugizaki, Kaito (speaker) (University of Tokyo (JP))
The Large Hadron Collider and the ATLAS experiment at CERN will explore new frontiers in physics in Run 3 starting in 2022. In the Run 3 ATLAS Level-1 endcap muon trigger, new detectors called New Small Wheel and additional Resistive Plate Chambers will be installed to improve momentum resolution and to enhance the rejection of fake muons.

Understanding ATLAS infrastructure behaviour with an Expert System / Asensi Tortajada, Ignacio (speaker) (Univ. of Valencia and CSIC (ES))
The ATLAS detector requires a huge infrastructure consisting of numerous interconnected systems forming a complex mesh which requires constant maintenance and upgrades. The ATLAS Technical Coordination Expert System provides, by the means of a user interface, a quick and deep understanding of the infrastructure, which helps to plan interventions by foreseeing unexpected consequences, and to understand complex events when time is crucial in the ATLAS control room.

Development of the Safety System for the Inner Tracking System of the ALICE Experiment / Mendez Lorenzo, Patricia (speaker) (CERN)
During the LHC Long Shutdown 2, the ALICE experiment has undergone numerous upgrades to cope with the large amount of data expected in Run3. Among all new elements integrated into ALICE, the experiment counts with a new Inner Tracking System (ITS), equipped with innovative pixel sensors that will substantially improve the performance of the system.

Enabling interoperable data and application services in a federated ScienceMesh / Arora, Ishank (speaker) (CERN)
In recent years, cloud sync & share storage services, provided by academic and research institutions, have become a daily workplace environment for many local user groups in the High Energy Physics (HEP) community. These, however, are primarily disconnected and deployed in isolation from one another, even though new technologies have been developed and integrated to further increase the value of data. [...]

Design of a Resilient, High-Throughput, Persistent Storage System for the ATLAS Phase-II DAQ System / Bonaventura, Matias Alejandro (speaker) (CERN)
The ATLAS experiment will undergo a major upgrade to take advan- tage of the new conditions provided by the upgraded High-Luminosity LHC. The Trigger and Data Acquisition system (TDAQ) will record data at unprece- dented rates: the detectors will be read out at 1 MHz generating around 5 TB/s of data. [...]
