MAESTRO, CASTRO, and SEDONA -- Petascale Codes for Astrophysical Applications
摘要：
对Ia型超新星（SNe Ia）进行高分辨率、高保真度的三维模拟，不仅需要精确表示正确物理的算法，还需要有效利用最强大超级计算机资源的代码。我们正在开发一套代码，提供的能力，以执行端到端的模拟超新星Ia，从早期的对流阶段导致点火的爆炸阶段，其中爆燃/爆震波爆炸的恒星的光变曲线的计算产生的爆炸。在本文中，我们将讨论这些代码的重点技术需要将它们扩展到千万亿次架构。我们还展示了我们的能力，映射数据从低马赫数制定一个可压缩的求解器。
英文摘要：
Performing high-resolution, high-fidelity, three-dimensional simulations of Type Ia supernovae (SNe Ia) requires not only algorithms that accurately represent the correct physics, but also codes that effectively harness the resources of the most powerful supercomputers. We are developing a suite of codes that provide the capability to perform end-to-end simulations of SNe Ia, from the early convective phase leading up to ignition to the explosion phase in which deflagration/detonation waves explode the star to the computation of the light curves resulting from the explosion. In this paper we discuss these codes with an emphasis on the techniques needed to scale them to petascale architectures. We also demonstrate our ability to map data from a low Mach number formulation to a compressible solver.
