thunderbolt-ibverbs: We have InfiniBand at home
A developer has created a project called thunderbolt-ibverbs that enables InfiniBand networking over Thunderbolt fabric. This setup connects two AMD Strix Halo mini-PCs using USB4 cables and a custom Linux kernel module. The resulting network achieves approximately 48 Gb/s per direction, significantly outperforming standard Ethernet and soft-RoCE over Thunderbolt. AI
