Hot discussion: running multi-GPU inference via a single slot with a PCIe switch

A developer shares a C-Payne PCIe switch setup that attaches multiple GPUs to a single slot for inference, noting inference traffic is only KB-scale. Follow-up discussion probes the card-count threshold and its fit for hybrid GPU+RAM+NVMe inference.
