Grace是是今天最引人注目的产品,名字来自计算机科学家Grace Hopper。而这颗芯片,是一款为大规模人工智能和高性能计算应用而设计的CPU,英伟达认为,AI模型的数据量和规模正在成倍增长。当今最大的AI模型包括数十亿个参数,并且每两个半月就会翻一番。训练它们需要一个新的CPU,可以与GPU紧密结合,以消除系统瓶颈。

Grace内置Arm Neoverse内核,官方宣称性能基础是第四代NVIDIA NVLink互连技术,该技术在Grace和NVIDIA GPU之间连接速度超过900GB/s,相当于目前服务器14倍的带宽;从CPU到CPU的速度超过600GB/s。

Grace还将采用LPDDR5x内存子系统,与DDR4内存相比,可提供两倍的带宽和10倍的能效。此外,新的架构提供了统一的缓存一致性和单一的内存地址空间,将系统和HBM GPU内存结合在一起,简化了可编程性。

Grace将得到NVIDIA HPC软件开发包和全套CUDA和CUDA-X库的支持,这些库可以加速超过2000个GPU应用。

Grace CPU预计将于2023年初上市,瑞士国家超级计算机中心(CSCS)和美国能源部的洛斯阿拉莫斯国家实验室(Los Alamos National Laboratory)将率先建造NVIDIA CPU驱动的超级计算机。
