V100, A100, H100
Streaming Multiprocessor (SM), Compute Unit (AMD)
SuperPOD
Compute Nodes: 40ea DGX A100 system(8x A100)
A100 80GB부터는 VRAM이 80GB. V100까지는 16/32GB까지만 제공되어 insufficient memory error가 잦았다.

Legend:
X = Self
SYS = Connection traversing PCIe as well as the SMP interconnect between NUMA nodes (e.g., QPI/UPI)
NODE = Connection traversing PCIe as well as the interconnect between PCIe Host Bridges within a NUMA node
PHB = Connection traversing PCIe as well as a PCIe Host Bridge (typically the CPU)
PXB = Connection traversing multiple PCIe bridges (without traversing the PCIe Host Bridge)
PIX = Connection traversing at most a single PCIe bridge
NV# = Connection traversing a bonded set of # NVLinks
