ExaStar 项目旨在为在百亿亿次机器上运行的多物理场天体物理模拟提供高效、多功能且可移植的软件生态系统。该代码套件是一个基于组件的多物理场工具包，建立在当前仿真代码（特别是 Flash-X 和 Castro）的功能之上，并基于大规模并行自适应网格细化框架 AMReX。它包括流体动力学、先进辐射传输、热核动力学和核微物理模块。通过构建集成到编排系统中的当前多核和众核包，该代码将达到百亿亿级效率，该编排系统使用配置工具、代码转换器和特定于域的异步运行时的组合来管理一系列平台架构的性能。目标科学包括天体物理爆炸（例如超新星和中子星合并）的多物理模拟，以了解元素的宇宙起源以及极端条件下物质和中微子的基础物理。
The ExaStar project aims to deliver an efficient, versatile, and portable software ecosystem for multi-physics astrophysics simulations run on exascale machines. The code suite is a component-based multi-physics toolkit, built on the capabilities of current simulation codes (in particular Flash-X and Castro), and based on the massively parallel adaptive mesh refinement framework AMReX. It includes modules for hydrodynamics, advanced radiation transport, thermonuclear kinetics, and nuclear microphysics. The code will reach exascale efficiency by building upon current multi- and many-core packages integrated into an orchestration system that uses a combination of configuration tools, code translators, and a domain-specific asynchronous runtime to manage performance across a range of platform architectures. The target science includes multi-physics simulations of astrophysical explosions (such as supernovae and neutron star mergers) to understand the cosmic origin of the elements and the fundamental physics of matter and neutrinos under extreme conditions.
