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.

AST-0113571J。这项研究的成果将是一个改进的通用求解器，用于天体物理气体动力学，包括磁流体动力学，自引力和辐射冷却效应。 它将是PI广泛使用的ZEUS代码的继承者，并且将是利用新的硬件和软件功能的新一代代码。 针对标量处理器优化的求解器能够在分布式存储器并行机上运行，这将极大地提高直接数值模拟可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课程相连接，该课程将允许在天体物理学数值模拟和并行架构数值算法的使用方面进行研究生培训。
