DGX H100 vs DGX GH200 256 GPU SuperPod Memory Common Address Space

My understanding is that the DGX H100 SuperPods only share a common address space among the 8GPUs within a BasePod. Is this the same with the DGX GH200 systems? The language in the DGX GH200 tech blog ( NVIDIA DGX GH200 Tech Blog) seems to indicate that the DGX GH200 has a full common shared address space for all 256 GH200 devices. If this is the case, can we assume that the NVLink “network” is not needed for DGX GH200, as NVLink Network endpoints do not share common memory address space.

Thanks in advance!
