2017有好戏看了，美国有2套100P+级别的超算开始建造

U.S. sets sights on 300 petaflop supercomputer

Summit will feature more than 3,400 nodes, each with:
Summit包含超过3400个节点，每个节点包括

    Multiple IBM POWER9 processors and multiple NVIDIA Volta GPUs
    多路IBM POWER9处理器和多路的NVIDIA Volta GPU （话说，POWER9是个什么玩意？）

    CPUs and GPUs completely connected with high speed NVLink
    CPU和GPU由高速的NVLink互联

    Large coherent memory: more than 512 GB of combined DDR4 and high bandwidth memory—all directly addressable from the CPUs and GPUs
    海量相联存储：超过512GB的混合DDR4及高带宽内存（指的是显存吧），二者均可通过CPU和GPU寻址

    An additional 800 GB of NVRAM, which can be configured as either a burst buffer or as extended memory
    附加800GB的NVRAM，它可被配置为突发缓存或扩展内存

    over 40 TF peak performance
    超过40Tflops的性能（按3400节点，每节点40TF计算的话，相当于136PF）

Summit will have a dual-rail Mellanox EDR interconnect configured as a full, non-blocking fat-tree. The file system will be a GPFS Storage Server system with 1TB/s I/O bandwidth and 120 PB of disk capacity.
Summit包括一个双轨制的Mellanox EDR（可能是infiniband EDR 4X，当然也可能是12X，Mellanox早就有4X的商业化产品了)，非阻塞的胖树架构网络，GPFS文件系统将有每秒1TB的吞吐量和120PB的容量。

Summit位于橡树岭，另一套相同配置（有说法是100P级别）的Sierra位于劳伦斯里弗莫尔

阿贡也发布了一套70P级别的机器
