A Flexible and Efficient Approach to Missing Transverse Momentum Reconstruction. 一种灵活高效的缺失横动量重构方法。

Missing transverse momentum is a crucial observable for physics at hadron colliders, being the only constraint on the kinematics of "invisible" objects such as neutrinos and hypothetical dark matter particles. Computing missing transverse momentum at the highest possible precision, particularly in experiments at the energy frontier, can be a challenging procedure due to ambiguities in the distribution of energy and momentum between many reconstructed particle candidates. This paper describes a novel solution for efficiently encoding information required for the computation of missing transverse momentum given arbitrary selection criteria for the constituent reconstructed objects. Pileup suppression using information from both the calorimeter and the inner detector is an integral component of the reconstruction procedure. Energy calibration and systematic variations are naturally supported. Following this strategy, the ATLAS Collaboration has been able to optimise the use of missing transverse momentum in diverse analyses throughout Runs 2 and 3 of the Large Hadron Collider and for future analyses.

缺失横动量是强子对撞机物理学的一个重要观测指标,是对中微子和假想暗物质粒子等 "隐形 "物体运动学的唯一约束。由于许多重构粒子候选体之间能量和动量分布的模糊性,以尽可能高的精度计算缺失的横动量,尤其是在能量前沿实验中,可能是一个具有挑战性的过程。本文介绍了一种新颖的解决方案,它可以有效地编码计算缺失横动量所需的信息,并给出组成重构对象的任意选择标准。利用量热计和内部探测器的信息抑制堆积是重建程序的一个组成部分。能量校准和系统变化自然也会得到支持。按照这一策略,ATLAS 协作组能够在大型强子对撞机运行 2 和 3 期的各种分析中以及在未来的分析中优化使用缺失横动量。

The offline software framework of the LHCb experiment has undergone a significant overhaul to tackle the data processing challenges that will arise in the upcoming Run 3 and Run 4 of the Large Hadron Collider. This paper introduces FunTuple, a novel component developed for offline data processing within the LHCb experiment. This component enables the computation and storage of a diverse range of observables for both reconstructed and simulated events by leveraging on the tools initially developed for the trigger system. This feature is crucial for ensuring consistency between trigger-computed and offline-analysed observables. The component and its tool suite offer users flexibility to customise stored observables, and its reliability is validated through a full-coverage set of rigorous unit tests. This paper comprehensively explores FunTuple's design, interface, interaction with other algorithms, and its role in facilitating offline data processing for the LHCb experiment for the next decade and beyond.

为了应对大型强子对撞机即将进行的运行 3 和运行 4 中出现的数据处理挑战,大型强子对撞机 b 实验的离线软件框架进行了重大改革。本文介绍了为大型强子对撞机实验离线数据处理而开发的新型组件 FunTuple。通过利用最初为触发系统开发的工具,该组件能够计算和存储重建和模拟事件的各种观测值。这一功能对于确保触发计算的观测数据与离线分析的观测数据之间的一致性至关重要。该组件及其工具套件为用户提供了定制存储观测值的灵活性,其可靠性通过一套全覆盖的严格单元测试得到了验证。本文全面探讨了 FunTuple 的设计、界面、与其他算法的交互,以及它在未来十年及以后促进 LHCb 实验离线数据处理方面的作用。

Simulated events are key ingredients in almost all high-energy physics analyses. However, imperfections in the simulation can lead to sizeable differences between the observed data and simulated events. The effects of such mismodelling on relevant observables must be corrected either effectively via scale factors, with weights or by modifying the distributions of the observables and their correlations. We introduce a correction method that transforms one multidimensional distribution (simulation) into another one (data) using a simple architecture based on a single normalising flow with a boolean condition. We demonstrate the effectiveness of the method on a physics-inspired toy dataset with non-trivial mismodelling of several observables and their correlations.

模拟事件是几乎所有高能物理分析的关键要素。然而,模拟的不完美会导致观测数据与模拟事件之间的巨大差异。必须通过标度因子、权重或修改观测值的分布及其相关性来有效地纠正这种误模拟对相关观测值的影响。我们介绍了一种校正方法,该方法利用一个基于布尔条件的单一归一化流的简单架构,将一种多维分布(模拟)转换为另一种多维分布(数据)。我们在一个受物理学启发的玩具数据集上演示了该方法的有效性,该数据集包含多个观测值及其相关性的非三维错模。

Computing demands for large scientific experiments, such as the CMS experiment at the CERN LHC, will increase dramatically in the next decades. To complement the future performance increases of software running on central processing units (CPUs), explorations of coprocessor usage in data processing hold great potential and interest. Coprocessors are a class of computer processors that supplement CPUs, often improving the execution of certain functions due to architectural design choices. We explore the approach of Services for Optimized Network Inference on Coprocessors (SONIC) and study the deployment of this as-a-service approach in large-scale data processing. In the studies, we take a data processing workflow of the CMS experiment and run the main workflow on CPUs, while offloading several machine learning (ML) inference tasks onto either remote or local coprocessors, specifically graphics processing units (GPUs). With experiments performed at Google Cloud, the Purdue Tier-2 computing center, and combinations of the two, we demonstrate the acceleration of these ML algorithms individually on coprocessors and the corresponding throughput improvement for the entire workflow. This approach can be easily generalized to different types of coprocessors and deployed on local CPUs without decreasing the throughput performance. We emphasize that the SONIC approach enables high coprocessor usage and enables the portability to run workflows on different types of coprocessors.

未来几十年,大型科学实验(如欧洲核子研究中心大型强子对撞机的 CMS 实验)的计算需求将急剧增加。为了补充未来中央处理器(CPU)上运行的软件性能的提高,探索在数据处理中使用协处理器具有巨大的潜力和意义。协处理器是一类计算机处理器,是中央处理器的补充,通常能通过架构设计的选择改善某些功能的执行。我们探索了协处理器上的优化网络推理服务(SONIC)方法,并研究了在大规模数据处理中部署这种即服务方法的问题。在研究中,我们采用了 CMS 实验的数据处理工作流程,在 CPU 上运行主要工作流程,同时将若干机器学习(ML)推理任务卸载到远程或本地协处理器(特别是图形处理器(GPU))上。通过在谷歌云、普渡大学二级计算中心以及两者的结合处进行的实验,我们展示了这些 ML 算法在协处理器上的加速效果,以及整个工作流相应吞吐量的提高。这种方法可以很容易地推广到不同类型的协处理器上,并部署在本地 CPU 上,而不会降低吞吐量性能。我们强调,SONIC 方法能够提高协处理器的使用率,并可移植到不同类型的协处理器上运行工作流。

Abstract Research in high energy physics (HEP) requires huge amounts of computing and storage, putting strong constraints on the code speed and resource usage. To meet these requirements, a compiled high-performance language is typically used; while for physicists, who focus on the application when developing the code, better research productivity pleads for a high-level programming language. A popular approach consists of combining Python, used for the high-level interface, and C++, used for the computing intensive part of the code. A more convenient and efficient approach would be to use a language that provides both high-level programming and high-performance. The Julia programming language, developed at MIT especially to allow the use of a single language in research activities, has followed this path. In this paper the applicability of using the Julia language for HEP research is explored, covering the different aspects that are important for HEP code development: runtime performance, handling of large projects, interface with legacy code, distributed computing, training, and ease of programming. The study shows that the HEP community would benefit from a large scale adoption of this programming language. The HEP-specific foundation libraries that would need to be consolidated are identified.
高能物理(HEP)的研究需要大量的计算和存储,这对代码速度和资源使用有很强的限制。为了满足这些要求,通常使用编译的高性能语言;而对于在开发代码时专注于应用程序的物理学家来说,更高的研究效率需要一种高级编程语言。一种流行的方法是将Python(用于高级接口)和c++(用于代码的计算密集型部分)结合起来。更方便和有效的方法是使用既提供高级编程又提供高性能的语言。由麻省理工学院开发的Julia编程语言遵循了这条道路,它特别允许在研究活动中使用单一语言。本文探讨了使用Julia语言进行HEP研究的适用性,涵盖了对HEP代码开发很重要的不同方面:运行时性能、大型项目的处理、与遗留代码的接口、分布式计算、培训和编程的便利性。研究表明,HEP社区将受益于这种编程语言的大规模采用。确定了需要合并的特定于hep的基础库。

A more convenient and efficient approach would be to use a language that provides both high-level programming and high-performance. The Julia programming language, developed at MIT especially to allow the use of a single language in research activities, has followed this path. In this paper the applicability of using the Julia language for HEP research is explored, covering the different aspects that are important for HEP code development: runtime performance, handling of large projects, interface with legacy code, distributed computing, training, and ease of programming. The study shows that the HEP community would benefit from a large scale adoption of this programming language. The HEP-specific foundation libraries that would need to be consolidated are identified.","PeriodicalId":36026,"journal":{"name":"Computing and Software for Big Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135482671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
