Intellectual Merit: This project will demonstrate a performance annotations approach to tune a production simulation code for use with computers containing more than O(1000) multicore processors. The code to be optimized is FLASH, a publicly available astrophysical simulation code. The work will focus on three code units of broad interest to the astrophysical simulation community:hydrodynamics (Euler equations), particle transport, and gravitation (Poisson?s equation). PI will focus on two machines, the TACC Ranger machine and the Argonne BlueGene/P, both of which are new and relatively untested architectures.Broader Impact:The annotation based approach to tunig codes for petascale can have tremendous impact on a number of other "legacy codes" if successful

智力优势：这个项目将展示一个性能注释方法，用于调整生产模拟代码，以用于包含超过O（1000）多核处理器的计算机。要优化的代码是FLASH，这是一种公开可用的天体物理模拟代码。 这项工作将集中在天体物理模拟社区广泛感兴趣的三个代码单元：流体力学（欧拉方程），粒子输运和引力（泊松？s方程）。PI将集中在两台机器上，TACC Ranger机器和阿贡BlueGene/P，这两台机器都是新的，相对未经测试的架构。更广泛的影响：如果成功的话，基于注释的千万亿次tunig代码方法可以对许多其他“遗留代码”产生巨大的影响
