Tesla’s TTPoE at Hot Chips 2024: Replacing TCP for Low Latency Applications
Last year at Hot Chips 2023, Tesla introduced their Dojo supercomputer. For Tesla, machine learning is focused on automotive applications like self driving cars. Training deals with video, which ca…
Tesla doesn’t intend to run TTP over the low quality links of the open internet, and therefore takes a brute force approach to congestion control. Tesla justified this approach by noting that traditional TCP congestion control algorithms like Reno work on too long of a timescale to be effective for their Dojo supercomputer application. Tesla wants to deploy large numbers of host nodes to feed their Dojo supercomputer, and having cheap network cards helps achieve that in a cost efficient manner.
