This is using Thunderbolt networking as transport, which incurs a bit of overhead.

But starting with the upcoming Linux v7.2, there's a new feature called USB4STREAM to use raw Thunderbolt packets as transport with minimum overhead and a super simple user interface:

Release of v7.2-rc1 is predicted for Jul 5, that's when this will first be available as a tarball. Until then you have to clone from thunderbolt.git/next:

Or alternatively linux-next:

Kudos for the idea and being fully open to the state of this project (AI code, expect breakage)!

Sounds like the old days using Firewire as an IP transport to get 400/800Mbps PtP networks. Interesting hack.

Nice project but you should be able to get infiniband up between a pair of Linux boxes with cheap adapters / cables off ebayy

Fascinating. Infiniband is already fascinating, running it on something else is more fascinating.
