在本文中，我们展示了Isambard的性能结果，Isambard是第一台基于Arm cpu的生产超级计算机，专门针对HPC进行了优化。Isambard是首款Cray XC50“Scout”系统，结合了基于Cavium ThunderX2 Arm的cpu和Cray的Aries互连。完整的Isambard系统将于2018年夏天交付，届时它将包含超过10,000个Arm内核。在这项工作中，我们展示了2018年3月升级到B0 beta硅的八个早期接入节点的节点级性能结果。我们展示了ThunderX2与主流cpu（包括英特尔Skylake和Broadwell以及Xeon Phi）的节点级基准测试结果。我们专注于一系列对英国国家HPC服务ARCHER以及Isambard项目合作伙伴和更广泛的HPC社区重要的应用程序和小应用程序。我们还比较了Arm的三个主要软件工具链的性能：Cray的CCE， Arm的Clang/Flang/LLVM版本，以及GNU。
In this paper, we present performance results from Isambard, the first production supercomputer to be based on Arm CPUs that have been optimized specifically for HPC. Isambard is the first Cray XC50 “Scout” system, combining Cavium ThunderX2 Arm‐based CPUs with Cray's Aries interconnect. The full Isambard system will be delivered in the summer of 2018, when it will contain over 10 000 Arm cores. In this work, we present node‐level performance results from eight early‐access nodes that were upgraded to B0 beta silicon in March 2018. We present node‐level benchmark results comparing ThunderX2 with mainstream CPUs, including Intel Skylake and Broadwell, as well as Xeon Phi. We focus on a range of applications and mini‐apps important to the UK national HPC service, ARCHER, as well as to the Isambard project partners and the wider HPC community. We also compare performance across three major software toolchains available for Arm: Cray's CCE, Arm's version of Clang/Flang/LLVM, and GNU.
