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更加复杂和逼真，导致了各种复杂的模拟平台，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，大多数数据分析是使用单独开发的工具进行的，并针对特定的模拟平台或研究领域；天体物理研究人员之间很少有系统和直接的技术转让。Yt项目是一个平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。该项目将能够开发先进的、基于物理的模块，这些模块普遍适用于模拟代码，促进科学研究，并能够更有效地利用计算和人力资源。通过这样做，它将有助于推进从黑洞双星研究到宇宙结构增长的无数研究目标。此外，该项目将成为许多研究不同现象的小组之间合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开发，吸引广泛的参与者。这项研究的基础设施开发将通过扩大YT内适用的模拟平台、实现微物理解算器和物理模块的跨代码利用以及现场分析，以及开发探索天体物理数据集的协作平台来实现这些能力。特别是，它将在三个主要机制中发展YT的能力。第一个是支持其他根本不同的模拟平台，例如平滑粒子流体动力学、非结构化网格和非笛卡尔坐标系。二是提供模拟仪器组件，以简化模拟代码的开发过程、这些模拟代码之间的接口和交换技术，并实现天体物理模拟代码与yt和其他分析工具包的更深层次的即时集成。最后一个重点是开发界面组件，以便能够利用基于网络的平台对数据进行协作和交互探索。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，重点是为贡献者和研究人员发展和鼓励合作、欢迎的环境，这一SSE将有助于培养一个对各方更容易进入的公平竞争环境，特别是妇女和代表性不足的少数群体。该项目的一个明确里程碑是通过科学可视化简化直接外联的过程，极大地扩大以STEM为基础的公共外联的领域和个人。

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.
