ITR/AP Development of a Next Generation Community Code for Astrophysical Gas Dynamics

AST-0113571J。斯通这项研究的成果将是一个改进的用于天体物理气体动力学的通用解算器，包括磁流体动力学、自重和辐射冷却效应。它将是PI广泛使用的Zeus代码的继任者，并将是利用新硬件和软件功能的新一代代码。针对能够在分布式内存并行机上运行的标量处理器进行优化的求解器将极大地扩大可通过直接数值模拟解决的天体物理问题的范围。该项目与科学计算和应用数学建模中心的研究生项目相衔接，该项目将允许在天体物理数值模拟和并行体系结构的数值算法使用方面进行研究生培训。

AST-0113571J. StoneThe product of this research will be an improved general purpose solver for astrophysical gas dynamics, including magnetohydrodynamics, self-gravity, and radiative cooling effects. It will be a successor to the PI's widely used ZEUS code and will be a new generation code exploiting new hardware and software capabilities. Solvers optimized for scalar processors able to run on distributed memory parallel machines will greatly enhance the range of astrophysical problems addressable with direct numerical simulation. The project is interfaced to the graduate program of the Center for Scientific Computation and Applied Mathematical Modeling, which will allow hands on graduate training in numerical simulations for astrophysics and in use of numerical algorithms for parallel architectures.
