The current number one of the TOP500 list, Supercomputer Fugaku, has demonstrated that CPU-only HPC systems aren't dead and CPUs can be used for more than just being the host controller for a discrete accelerators. While the specifications of the chip and overall system architecture, and benchmarks submitted to various lists, like TOP500 and Green500, etc., are clearly highlighting the potential, the proliferation of Arm into the HPC business is rather recent and hence the software stack might not be fully matured and tuned, yet. We test three state-of-the-art compiler suite against a broad set of benchmarks. Our measurements show that orders of magnitudes in performance can be gained by deviating from the recommended usage model of the A64FX compute nodes.

A64FX——您必须决定的编译器！

目前在 TOP500 名单中排名第一的 Supercomputer Fugaku 已经证明，仅使用 CPU 的 HPC 系统并没有消亡，CPU 不仅可以用作离散加速器的主机控制器。虽然芯片和整体系统架构的规格，以及提交到各种列表的基准，如 TOP500 和 Green500 等，都清楚地突出了潜力，但 Arm 进入 HPC 业务的扩散是最近的，因此软件堆栈可能不会完全成熟和调整，但。我们根据广泛的基准测试测试了三个最先进的编译器套件。我们的测量表明，通过偏离 A64FX 计算节点的推荐使用模型，可以获得几个数量级的性能。
