NVIDIA NVLink on a Mac
GPU-to-GPU interconnect; per-link state & bandwidth · Storage & NAS
NVLink is NVIDIA's high-bandwidth GPU-to-GPU interconnect (within a node/board). Monitor with nvidia-smi: nvidia-smi nvlink --status (per-link up/speed), nvidia-smi nvlink -gt d (throughput counters), and nvidia-smi topo -m (the GPU/NIC topology matrix; NV# = NVLink hops). DCGM (dcgmi) exposes NVLink bandwidth/errors as fields for monitoring. No macOS GPUs; check it on your Linux GPU hosts (GPU Fabric Manager / AI Harness over SSH).
