CSSI Elements: EWMS - Event Workflow Management Service

该奖项将开始开发观测管理系统框架，这将有助于减轻多种类型的天体物理数据和相应的工作流程管理--这是目前由处理大量独立数据(“事件”)的人类研究人员承担的负担。该框架的核心元素-事件工作流管理系统(EWMS)-是一个为处理事件(粒子物理探测器的模拟读数、记录的数据点、图像等)而设计的工作负载管理器。使用复杂的工作流程。EWMS可能成为应用新的计算机科学方法来改进科学数据处理的核心，最初的重点是多信使天体物理学(MMA)-它将通过一套可重复使用的服务，改变国家CI生态系统处理基于事件的计算问题的方式。这一范式适用于广泛的科学领域，包括天体物理学、天文学、物理学、生物学和其他处理大数据流动的学科。EWMS将惠及美国国家科学基金会十大构想中的三个--“不断增长的融合研究”、“利用数据革命”和“宇宙之窗”，汇集了基于粒子物理的探测器(冰立方中微子天文台、高海拔水切伦科夫天文台、切伦科夫望远镜阵列)、传统天文观测台(大型望远镜)和引力波观测台(LIGO、处女座、KAGRA)的数据。虽然每个实验或观测站的数据类型都有很大不同，但它们都以独立的时空增量、观测、触发、事件等方式记录数据，这些数据分别进行处理和存储。EWMS适用于MMA实验中几乎所有当前的工作流程，通过EWMS结合这些最精确的观测，科学家将能够以全新的方式观察宇宙，并了解更多关于宇宙历史的信息，而这些信使中的任何一个都无法单独提供。因此，该奖项阐述并推进了美国国家科学基金会“宇宙之窗：多信使天体物理时代”计划的科学目标和目标。这一奖项由高级网络基础设施办公室颁发，由宇宙之窗计划、信息前沿物理计划、冰立方科学计划、南极天体物理和地球空间科学计划以及极地计划办公室网络基础设施计划联合支持。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This award will begin developing an Observation Management System Framework which will help alleviating multiple types of astrophysical data and respective workflow management - a burden shouldered now by human researchers who process large numbers of independent pieces of data (“events”). The core element of this framework - Event Workflow Management System (EWMS) - is a workload manager designed for processing events (simulated readouts from a particle physics detector, recorded data points, images, etc.) with complex workflows. EWMS could become a central core for applying novel computer science methods to improve scientific data processing with an initial focus on Multi-Messenger Astrophysics (MMA) - it will transform how ”event”-based computational problems are tackled on the national CI ecosystem through a set of reusable services. This paradigm is applicable across a wide range of science domains, including astrophysics, astronomy, physics, biology, and other disciplines that deal with Big Data flows. The EWMS will benefit three of NSF’s 10 big ideas – “Growing Convergence Research,” “Harnessing the Data Revolution,” and “Windows on the Universe", bringing together data from the particle physics-based detectors (IceCube Neutrino Observatory, High Altitude Water Cherenkov Observatory, Cherenkov Telescope Array), traditional astronomical observatories (large telescopes), and gravitational wave observatories (LIGO, VIRGO, KAGRA). While the data types of each of these experiments or observatories are dramatically different, they all record data in the independent spatio-temporal increments, observations, triggers, events, etc. that are processed and stored separately. The EWMS is applicable to nearly all current workflows in MMA experiments, and by combining these most precise observations via EWMS, scientists will be able to observe the Universe in fundamentally new ways and learn more about its history than any one of these messengers can provide in isolation. Thus, this award addresses and advances the science objectives and goals of the NSF's "Windows on the Universe: The Era of Multi-Messenger Astrophysics" program.This award by the Office of Advanced Cyberinfrastructure is jointly supported by the Windows on the Universe Program, the Physics at the Information Frontier Program, the IceCube Science Program, the Antarctic Astrophysics and Geospace Sciences Program, and the Office of Polar Programs CyberInfrastructure Program.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
