  • 2019 GDD breaking world‘s record of π

    Day 2

    1、breaking pi‘s world record with google cloud 

    【concept】

    memory wall:

    Originally theorized in 1994 by Wulf and McKee, this concept revolves around the idea that computer processing units (CPUs) are advancing at a fast enough pace that will leave memory (RAM) stagnant. This isn’t going to happen immediately, but assuming current trends in CPU and RAM remain the same, we could hit a memory wall sometime in the near future.

    Once we reach this so-called memory wall, program/app execution time will depend almost entirely on the speed at which RAM can send data to the CPU. 

     n1-megamen-96:

    计算节点 96 vCPU, 1.4TB RAM ,单台ECS的配置。那么是否Google cloud的ECS已经突破了物理机限制,实现跨物理机的VM?

    查询Google 官网有如下VM机型介绍

    机器名称说明vCPU 数量1内存 (GB)永久性磁盘 (PD) 数上限2总 PD 容量大小上限 (TB)本地 SSD
    n1-megamem-96 具有 96 个 vCPU 和 1.4 TB 内存的内存优化机器类型。 96 1433.6 128 64
