π2.0 hardware specification

上海交通大学高性能计算中心的π 2.0超级计算机于2019年4月建成,双精度理论峰值性能为2.1 PFLOPS,是国内高校和上海地区最快的超算之一。π 2.0 是国内最早使用Intel Cascade Lake CPU 构建的超算,拥有656台计算节点,共计26000个CPU核,可同时支持HPC与AI应用。计算节点之间使用100Gbps 的Intel OmniPath 互联。并行存储的聚合存储能力为5PB,采用Lustre并行文件系统。为了更好的支持IO密集型应用,π 2.0 还在国内首次采用了基于Intel 全闪存NVMe 固态硬盘搭建的Lustre存储系统,π 2.0的详细配置如下表所示。

Built in April 2019, the supercomputer π2.0 of Shanghai Jiao Tong University has 2.1 Double-Precision PetaFlops in peak performance and is one of the fastest supercomputers among China's universities and in Shanghai. The supercomputer is the first in China to adopt Intel Cascade Lake Processors which can support both HPC and AI applications. It has 26000 CPU cores within 656 nodes. The nodes are connected with Intel Omni-Path 100Gbps. Its parallel storage is based on Lustre file system and has a 5PB capacity. To better support the I/O intensive applications, the supercomputer is the first in China to build Lustre storage system with 300TB Intel NVme SSDs.
