作为美国能源部高级计算科学发现（SciDAC）计划的一部分，科学团队正在解决需要在千万亿次计算机上进行模拟和建模的问题。作为SciDAC可扩展应用开发软件中心（CScADS）和性能工程研究所（PERI）相关活动的一部分，莱斯大学正在构建用于领先平台上科学应用性能分析的软件工具。在这篇海报摘要中，我们简要介绍了HPCToolkit性能工具，以及如何使用它们来查明SPMD和多线程并行代码中的瓶颈。我们证明了HPCToolkit的实用性，通过将其应用到两个SciDAC应用程序：用于模拟湍流燃烧的S3D代码和用于原子核微观结构从头计算的MFDn代码。
As part of the U.S. Department of Energy's Scientific Discovery through Advanced Computing (SciDAC) program, science teams are tackling problems that require simulation and modeling on petascale computers. As part of activities associated with the SciDAC Center for Scalable Application Development Software (CScADS) and the Performance Engineering Research Institute (PERI), Rice University is building software tools for performance analysis of scientific applications on the leadership-class platforms. In this poster abstract, we briefly describe the HPCToolkit performance tools and how they can be used to pinpoint bottlenecks in SPMD and multi-threaded parallel codes. We demonstrate HPCToolkit's utility by applying it to two SciDAC applications: the S3D code for simulation of turbulent combustion and the MFDn code for ab initio calculations of microscopic structure of nuclei.
