SI2-SSE: yt: Reusable Components for Simulating, Analyzing and Visualizing Astrophysical Systems

天体物理现象的计算建模已经变得越来越复杂和现实，导致了各种复杂的仿真平台，每个平台都利用自己的机制和格式来表示粒子和流体。同样，大多数数据分析都是使用孤立开发的工具进行的，并针对特定的仿真平台或研究领域；天体物理学研究人员之间很少有系统和直接的技术转让。该项目是一个并行分析和可视化工具包，旨在支持研究人员的协作社区，因为他们专注于回答物理问题，而不是阅读、处理和可视化数据格式的技术机制。该项目将开发先进的、基于物理的模块，这些模块普遍适用于模拟代码，推进科学探究，并使计算和人力资源得到更有效的利用。在这样做的过程中，它将有助于推进无数的研究目标，从黑洞双星的研究到宇宙结构的发展。此外，该项目将作为许多研究不同现象的小组之间协作和跨代码利用的试金石。此外，该项目将通过面向社区的进程发展，吸引广泛的参与者。本研究中的基础设施发展将通过扩大yt内适用的模拟平台，实现微物理求解器和物理模块的跨代码利用以及原位分析，以及开发用于探索天体物理数据集的协作平台，从而实现这些功能。特别地，它将在三个主要机制中发展它的能力。首先是支持额外的、根本不同的仿真平台，如光滑粒子流体动力学、非结构化网格和非笛卡尔坐标系。二是提供仿真仪器组件，以简化开发仿真代码的过程，在这些仿真代码之间进行接口和交换技术，并使天体物理仿真代码与yt和其他分析工具包进行更深入的实时集成。最后一个重点是开发接口组件，以便利用基于web的平台对数据进行协作和交互探索。这个SI2-SSE项目的一个明确目标是发展科学家之间的合作关系，促进整个领域的发展。通过公开开展所有业务，重点发展和鼓励合作，欢迎贡献者和研究人员的环境，SSE将有助于营造一个公平的竞争环境，使各方，特别是妇女和代表性不足的少数民族更容易获得。该项目的一个明确的里程碑是通过科学可视化简化进行直接外展的过程，极大地扩展了从事stem公共外展的领域和个人。

Computational modeling of astrophysical phenomena has grown in sophistication and realism, leading to a diversity of complex simulation platforms, each utilizing its own mechanism and format for representing particles and fluids. Similarly, most of the data analysis is conducted with tools developed in isolation and targeted to a specific simulation platform or research domain; very little systematic and direct technology transfer between astrophysical researchers exists. The yt project is a parallel analysis and visualization toolkit designed to support a collaborative community of researchers as they focus on answering physical questions, rather than the technical mechanics of reading, processing and visualizing data formats. This project will enable the development of advanced, physics-based modules that apply universally across simulation codes, advancing scientific inquiry and enabling more efficient utilization of computational and human resources. In doing so, it will help advance a myriad of research goals from the study of black hole binaries to the growth of cosmic structure. In addition, the project will serve as a touchstone for collaboration and cross-code utilization between many groups studying diverse phenomena. Moreover, the project will be developed through a community-oriented process, engaging a wide range of participants.The infrastructure development in this research will enable these capabilities by broadening the applicable simulation platforms within yt, enabling cross-code utilization of microphysical solvers and physics modules and in situ analysis, and developing collaborative platforms for the exploration of astrophysical datasets. In particular, it will develop the capabilities of yt in three primary mechanisms. The first is to enable support for additional, fundamentally different simulation platforms such as smoothed particle hydrodynamics, unstructured mesh, and non-Cartesian coordinate systems. The second is to provide simulation instrumentation components to ease the process of developing simulation codes, interfacing and exchanging technology between those simulation codes, and to enable deeper, on-the-fly integration of astrophysical simulation codes with yt and other analysis toolkits. The final focus is on developing interface components to enable collaborative and interactive exploration of data utilizing web-based platforms. An explicit goal of this SI2-SSE project is the development of collaborative relationships between scientists, furthering the development of the field as a whole. By conducting all business in the open with a focus on developing and encouraging collaborative, welcoming environments for contributors and researchers, this SSE will help to foster a level playing field that is more accessible to all parties, particularly women and underrepresented minorities. An explicit milestone of this project is to streamline the process of conducting direct outreach through scientific visualization, greatly expanding the domains and individuals engaged in STEM-based public outreach.
