Ookami[3]是由美国国家科学基金会支持的计算机技术测试平台。它为研究人员提供了访问富士通[17]与RIKΞN合作开发的A64FX处理器的机会[35,37],用于日本的百亿亿次计算之路,部署在Fugaku[36]中,这是世界上最快的计算机[34]。通过专注于关键的架构细节,基于arm的多核512位simd矢量处理器具有超高带宽内存,承诺保留熟悉和成功的编程模型,同时为广泛的应用实现非常高的性能。我们回顾了相关的技术和系统细节,论文的主体集中在微基准,迷你应用程序和完整应用程序的硬件和软件生态系统的初步经验,并开始回答有关这些技术适合NSF生态系统的问题。
Ookami [3] is a computer technology testbed supported by the United States National Science Foundation. It provides researchers with access to the A64FX processor developed by Fujitsu [17] in collaboration with RIKΞN  [35, 37] for the Japanese path to exascale computing, as deployed in Fugaku [36], the fastest computer in the world [34]. By focusing on crucial architectural details, the ARM-based, multi-core, 512-bit SIMD-vector processor with ultrahigh-bandwidth memory promises to retain familiar and successful programming models while achieving very high performance for a wide range of applications. We review relevant technology and system details, and the main body of the paper focuses on initial experiences with the hardware and software ecosystem for micro-benchmarks, mini-apps, and full applications, and starts to answer questions about where such technologies fit into the NSF ecosystem.
