Experimental RDMA over USB4 via Thunderbolt IB Verbs Demonstrated on Strix Halo

A blog post describes an experimental implementation of RDMA over USB4 using Thunderbolt IB verbs, demonstrated on two Strix Halo machines. The author could not find any prior public posts on the topic, suggesting it is a novel approach. The implementation shows that RDMA can work with any USB4 host, potentially enabling high‑speed data transfer without a dedicated network interface. The demonstration was performed on two Strix Halo GPUs, highlighting the feasibility of using consumer hardware for RDMA. The post links to the blog for detailed technical information. The author notes that the implementation could be significant for future USB4‑based data pipelines. The demonstration indicates that USB4 can support low‑latency, high‑throughput communication. The post invites readers to experiment with the technique on their own USB4 devices.
