Description
Collaborative software and maintainability
The ATLAS offline code management system serves as a collaborative framework for developing a code base totaling more than 5 million lines. Supporting up to 50 nightly release branches, the ATLAS Nightly System offers abundant opportunities for updating existing software and developing new tools for forthcoming experimental stages within a multi-platform environment. This paper describes the...
The ATLAS experiment will undergo major upgrades for operation at the high luminosity LHC. The high pile-up interaction environment (up to 200 interactions per 40MHz bunch crossing) requires a new radiation-hard tracking detector with a fast readout.
The scale of the proposed Inner Tracker (ITk) upgrade is much larger than the current ATLAS tracker. The current tracker consists of ~4000...
XRootD is a robust, scalable service that supports globally distributed data management for diverse scientific communities. Within GridPP in the UK, XRootD is used by the Astronomy, High-Energy Physics (HEP) and other communities to access >100PB of storage. The optimal configuration for XRootD varies significantly across different sites due to unique technological frameworks and site-specific...
For over two decades, the dCache project has provided open-source to satisfy ever-more demanding storage requirements. More than 80 sites around the world, rely on dCache to provide services for LHC experiments, Belle-II, EuXFEL and many others. This can be achieved only with a well-established process from a whiteboard, where ideas are created, through development, packaging and testing. The...
ROOT is an open source framework, freely available on GitHub, at the heart of data acquisition, processing and analysis of HE(N)P experiments, and beyond.
It is developed collaboratively: contributions are not authored only by ROOT team members, but also by a veritable nebula of developers and scientists from universities, labs as well as the private sector. More than 1500 GitHub Pull...
The LHCb Software Framework Gaudi has been developed in C++ since 1998. Over the years it evolved following the changes in the C++ established best practices and the evolution of the C++ standard, even reaching the point of enabling the development of multi-threaded applications.
In the past few years there has been several announcements and debates over the so called C++ successor languages...
Recently, interest in measuring and improving the energy (and carbon) efficiency of computation in HEP, and elsewhere, has grown significantly. Measurements have been, and continue to be, made of the efficiency of various computational architectures in standardised benchmarks... but those benchmarks tend to compare only implementations in single programming languages. Similarly, comparisons of...
ROOT is a software toolkit at the core of LHC experiments and HENP collaborations worldwide, widely used by the community and in continuous development with it. The package is available through many channels that cater different types of users with different needs. This ranges from software releases on the LCG stacks provided via CVMFS for all HENP users to benefit, to pre-built binaries...
In the vast landscape of CERN's internal documentation, finding and accessing relevant detailed information remains a complex and time-consuming task. To address this challenge, the AccGPT project proposes the development of an intelligent chatbot leveraging Natural Language Processing (NLP) technologies. The primary objective is to harness open-source Large Language Models (LLMs) to create a...
The LHCb collaboration continues to primarily utilize the Run 1 and Run 2 legacy datasets well into Run 3. As the operational focus shifts from the legacy data to the live Run 3 samples, it is vital that a sustainable and efficient system is in place to allow analysts to continue to profit from the legacy datasets. The LHCb Stripping project is the user-facing offline data-processing stage...
I will be presenting the history of the design, implementation, testing, and release of the production version of a C++-based software for the Gas Gain Stabilization System (GGSS) used in the TRT detector at the ATLAS experiment. This system operates 24/7 in the CERN Point1 environment under the control of the Detector Control System (DCS) and plays a crucial role in delivering reliable data...
Given the recent slowdown of the Moore’s Law and increasing awareness of the need for sustainable and edge computing, physicists and software developers can no longer just rely on computer hardware becoming faster and faster or moving processing to the cloud to meet the ever-increasing computing demands of their research (e.g. the data rate increase in HL-LHC). However, algorithmic...
The software framework of the Large Hadron Collider Beauty (LHCb) experiment, Gaudi, heavily relies on the ROOT framework and its I/O subsystems for data persistence mechanisms. Gaudi internally leverages the ROOT TTree data format, as it is currently used in production by LHC experiments. However, with the introduction and scaling of multi-threaded capabilities within Gaudi, the limitations...
A data quality assurance (QA) framework is being developed for the CBM experiment. It provides flexible tools for monitoring of reference quantity distributions for different detector subsystems and data reconstruction algorithms. This helps to identify software malfunctions and calibration status, to prepare a setup for the data taking and to prepare data for the production. A modular...
CHEP Track: 6 - Collaborative software and maintainability
The LHCb high-level trigger applications consists of components that run reconstruction algorithms and perform physics object selections, scaling from hundreds to tens of thousands depending on the selection stage. The configuration of the components, the data flow and the control flow are implemented in Python. The resulting...
At the core of CERN's mission lies a profound dedication to open science; a principle that has fueled decades of ground-breaking collaborations and discoveries. This presentation introduces an ambitious initiative: a comprehensive catalogue of CERN's open-source projects, purveyed by CERN’s own OSPO. The mission? To spotlight every flag-bearing and nascent project under the CERN umbrella,...
The Key4hep software stack enables studies for future collider projects. It provides a full software suite for doing event generation, detector simulation as well as reconstruction and analysis. In the Key4hep stack, over 500 packages are built using the spack package manager and deployed via the cvmfs software distribution system. In this contribution, we explain the current setup for...
The Spack package manager has been widely adopted in the supercomputing community as a means of providing consistently built on-demand software for the platform of interest. Members of the high-energy and nuclear physics (HENP) community, in turn, have recognized Spack’s strengths, used it for their own projects, and even become active Spack developers to better support HENP needs. Code...
The ePIC collaboration is working towards realizing the primary detector for the upcoming Electron-Ion Collider (EIC). As ePIC approaches critical decision milestones and moves towards future operation, software plays a critical role in systematically evaluating detector performance and laying the groundwork for achieving the scientific goals of the EIC project. The scope and schedule of the...
The ePIC collaboration is realizing the first experiment of the future Electron-Ion Collider (EIC) at the Brookhaven National Laboratory that will allow for a precision study of the nucleon and the nucleus at the scale of sea quarks and gluons through the study of electron-proton/ion collisions. This talk will discuss the current workflow in place for running centralized simulation campaigns...
Considering CERN's prosperous environment, developing groundbreaking research in physics and pushing technology's barriers, CERN members participate in many talks and conferences every year. However, given that the ATLAS experiment has around 6000 members and more than one could be qualified to present the same talk, the experiment developed metrics to prioritize them.
Currently, ATLAS is...
CERN has a very dynamic environment and faces challenges such as information centralization, communication between the experiments’ working groups, and the continuity of workflows. The solution found for those challenges is automation and, therefore, the Glance project, an essential management software tool for all four large LHC experiments. Its main purpose is to develop and maintain...
