人工智能在计算能力方面处于领先地位
Atlas900AI训练集群采用业界单芯片算力最强的昇腾910AI处理器，每颗昇腾910AI处理器内置32个达芬奇AICore，单芯片提供比业界高一倍的算力。Atlas900AI训练集群将数千颗昇腾910AI处理器互联，打造业界第一的算力集群。
升腾910 AI处理器采用SoC设计，集成了"AI计算能力、通用计算能力、高速大带宽I≤O"，极大地卸载了主机CPU的数据预处理任务，充分提高了训练效率。
最优集群网络
亚特兰900 AI培训集群采用hccs、PCIe4.0、100 G三种高速互连方式，100 TB全互连无阻塞专用参数同步网络，降低网络延迟10≤，梯度同步延迟70%。
在AI服务器中，胜腾910AI处理器通过HCCS高速总线连接，升腾910AI处理器和CPU与最新的PCIe4.0(速率16Gb/s)技术相连接，其速度是业界主流PCIe3.0(8.0Gb/s)技术的两倍，使得数据传输速度更快、效率更高。在集群级，采用面向数据中心的CloudEngine 8800系列交换机提供单端口100 Gbps的交换速率，集群中的所有AI服务器都连接到高速交换网络。
采用原有的智能无损耗交换算法对集群中的网络流量进行实时训练，实现了网络0分组丢失和E2Eμ的延迟。
