Linux already has RDMA support but it cannot yet use Thunderbolt. It's probably quite a bit of work to add everything that's required. Is anyone working on it?

It would be great to have this for those cheap Strix Halo boxes with 128GB quad channel DDR5-8000 for using two or three of them with their 2 USB4 ports (which are Thunderbolt capable) to fit larger models.

- yonatan8070 10mo agoI assume that's Thunderbolt 5? From my experience, eGPUs over USB 4/TB3 work just fine (from a technical point of view, in practice 40Gbps isn't enough BW and performance is shit)
- Tepix 10mo agoYes, that works but what's needed here is remotely accessing RAM on another PC via RDMA via Thunderbolt. Not accessing a standalone eGPU.
