GH200 超级服务器

每个DGX系统的核心都是基板上的GPU复合体，基板上与NVLink互连，中每个GPU都可以以NVLink速度访问对方的内存。许多类带有GPU复合体的DGX通过高速网络互连，形成更大的超级计算机，例如NVIDIA Selene超级计算机。然而，一类新兴的巨型万亿参数Al模型要么需要几个月的训练时间，要么即使在当今好的超级计算机上地无法解决。
NVIDIA将NVIDIA Grace Hopper Superchip与NVLink开关系统配对，在NVIDIA DGX GH200系统中整合了多达256个GPU。在DGXGH200系统中，GPU共享内存编程模型可通过NVLink高速访问144 TB内存。与单个NVIDIA DGX A100 320 GB系统相比，NVIDIA DGX GH200通过NVLink为GPU共享内存编程模型提供了近500倍的内存，形成了一个巨大的数据中心大小的GPU。NVIDIA DGX GH200是第一台突破GPU通过NVLink访问内存的100 TB障碍的超级计算机。

Since then, the core of each DGX system has been a GPU complex on the substrate, which is interconnected with NVLink. Each GPU in the substrate can access each other's memory at NVLink speed. Many types of DGX with GPU complexes are interconnected through high-speed networks, forming larger supercomputers, such as NVIDIA Selene supercomputers. However, a class of emerging giant trillion parameter Al models either require several months of training time or cannot be solved even on today's good supercomputers.
NVIDIA paired NVIDIA Grace Hopper Superchip with NVLink switching system, integrating up to 256 GPUs in NVIDIA DGX GH200 system. In the DGXGH200 system, the GPU shared memory programming model can access 144 TB of memory at high speed through NVLink. Compared to a single NVIDIA DGX A100 320 GB system, the NVIDIA DGX GH200 provides nearly 500 times more memory for GPU shared memory programming models through NVLink, forming a huge data center sized GPU. The NVIDIA DGX GH200 is the first supercomputer to break through the 100 TB barrier of GPU access to memory through NVLink.
