InfiniBand networking achieved over Thunderbolt fabric

By PulseAugur Editorial · [5 sources] ·

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

IMPACT Demonstrates a novel approach to high-speed networking that could benefit AI training infrastructure.

RANK_REASON Technical write-up of a novel hardware/software project demonstrating a new capability.
