Over a fast thunderbolt 5 link you can transfer tens of GB in 2 minutes, with a Python script, or in 30 minutes with scp... This is a mix of many inefficiencies, it's not encryption overhead. Would be cool to have more decent tooling: security is often an excuse for bad things.

MLX's implementation of RDMA (Remote Direct Memory Access) over Thunderbolt on macOS, can now be used as an independent library by anyone: It is the gem that powers Mac clusters for local AI, and is an order of magnitude faster than protocols over TCP.

It’s so funny how the MCU post-Endgame wanted to adapt the same Avengers-less vacuum that created the Thunderbolts in the comics but since half of their heroes were still alive (unlike the Onslaught event) it just seems like nobody bothered to reassemble them.

exo featured on Apple's new M5 Ultra Mac Studio and M6 / M5 Pro Mac Mini pages. Over the past year, we have worked closely with Apple on low-latency RDMA networking over Thunderbolt 5, enabling clusters of Macs to run massive models like Kimi K3 and GLM-5.3 at API speeds. With RDMA, aggregate memory bandwidth across Macs scales ~linearly. A cluster of 4 x M5 Ultra Mac Studios scale to an aggregate memory bandwidth of ~4.8TB/s. Previously, these were speeds only achievable with data center GPUs. Our vision is a data center on every desk. Apple Silicon's superior memory unit economics, power efficiency, and out of the box experience for Local AI make that possible. Thank you to @angeloskath, @awnihannun, @twid and countless others at Apple who tirelessly to bring this technology to the world.
