Abstract

The introduction of heterogeneous computing via GPUs from the Sierra architecture represented a significant shift in direction for computational science at Lawrence Livermore National Laboratory (LLNL), and therefore required significant preparation. Over the last five years, the Sierra Center of Excellence (CoE) has brought employees with specific expertise from IBM and NVIDIA together with LLNL in a concentrated effort to prepare applications, system software, and tools for the Sierra supercomputer. This article shares the process we applied for the CoE and documents lessons learned during the collaboration, with the hope that others will be able to learn from both our success and intermediate setbacks. We describe what we have found to work for the management of such a collaboration and best practices for algorithms and source code, system configuration and software stack, tools, and application performance.
Sierra卓越中心:经验教训
Sierra架构通过gpu引入异构计算代表了劳伦斯利弗莫尔国家实验室(LLNL)计算科学方向的重大转变,因此需要大量的准备工作。在过去的五年中,Sierra卓越中心(CoE)将IBM和NVIDIA的专业人员与LLNL聚集在一起,集中精力为Sierra超级计算机准备应用程序、系统软件和工具。本文分享了我们申请CoE的过程,并记录了在协作过程中获得的经验教训,希望其他人能够从我们的成功和中间挫折中学习。我们描述了我们发现的对这种协作的管理以及算法和源代码、系统配置和软件堆栈、工具和应用程序性能的最佳实践的工作。
