Collaborative Research: SI2-SSI: Data-Intensive Analysis for High Energy Physics (DIANA/HEP)

先进的软件在大型科学项目中起着基础性的作用。Diana/HEP(高能物理数据密集型分析)的主要目标是开发最先进的实验工具，以获取、减少和分析PB级的数据。通过修改和添加社区广泛使用的包来提高性能、互操作性和协作工具，将使用户能够更充分地利用从CERN的大型强子对撞机(LHC)和其他设施获得的数据。这些实验正在解决物理学的核心问题：物质的基本成分是什么？它们是如何互动的？随着2012年希格斯玻色子的发现，粒子物理的标准模型完成了。它很好地描述了已知的粒子和力。然而，最有趣的问题仍然悬而未决：弥漫在宇宙中的暗物质是什么？时空有没有额外的对称性，或者超出了我们已知的3个空间维度？从巨大的量子修正中稳定希格斯玻色子质量的机制是什么？下一代实验将收集艾字节规模的数据样本，以提供答案。分析这些数据将需要新的更好的工具。首先，该项目将提供减少迭代时间所需的CPU和IO性能，而迭代时间对于探索新想法至关重要。它将开发软件，以有效地利用新兴的多核和多核硬件。它将建立更高水平的协作分析的基础设施，建立在希格斯玻色子发现所用的成功模式的基础上，并使理论界和实验界之间能够进行更深入的交流。戴安娜？S的产品将位于根框架中，该框架已经被HEP社区的10000多名粒子和核物理学家使用。通过改善与更大的科学软件生态系统的互操作性，戴安娜将把其他学科的最佳实践和算法纳入HEP。同样，该项目将向更大的科学界提供与协作分析、数据保存标准和将软件视为研究产品的最佳实践相关的计算见解、工具和新想法。最后，为了提高HEP下一代软件工程师的素质，戴安娜将主持一个关于分析工具的年度研讨会，并建立一个奖学金计划。

Advanced software plays a fundamental role for large scientific projects. The primary goal of DIANA/HEP (Data Intensive ANAlysis for High Energy Physics) is developing state-of-the-art tools for experiments that acquire, reduce, and analyze petabytes of data. Improving performance, interoperability, and collaborative tools through modifications and additions to packages broadly used by the community will allow users to more fully exploit the data being acquired at CERN's Large Hadron Collider (LHC) and other facilities. These experiments are addressing questions at the heart of physics: What are the underlying constituents of matter? And how do they interact? With the discovery of the Higgs boson in 2012, the Standard Model of particle physics is complete. It provides an excellent description of known particles and forces. However, the most interesting questions remain open: What is the dark matter which pervades the universe? Does space-time have additional symmetries or extend beyond the 3 spatial dimensions we know? What is the mechanism stabilizing the Higgs boson mass from enormous quantum corrections? The next generation of experiments will collect exabyte-scale data samples to provide answers. Analyzing this data will require new and better tools. First, the project will provide the CPU and IO performance needed to reduce the iteration time so crucial to explore new ideas. It will develop software to effectively exploit emerging many- and multi-core hardware. It will establish infrastructure for a higher-level of collaborative analysis, building on the successful patterns used for the Higgs boson discovery and enabling a deeper communication between the theoretical community and the experimental community. DIANA?s products will sit in the ROOT framework, already used by the HEP community of more than 10000 particle and nuclear physicists. By improving interoperability with the larger scientific software ecosystem, DIANA will incorporate best practices and algorithms from other disciplines into HEP. Similarly, the project will make its computing insights, tools, and novel ideas related to collaborative analysis, standards for data preservation, and best practices for treating software as a research product available to the larger scientific community. Finally, to improve the quality of the next generation of software engineers in HEP, DIANA will host an annual workshop on analysis tools and establish a fellowship program.
