Not directly related to Homa, but I'd like to point that the paper's author and presenter is none other than TCL programming language original designer John Ousterhout [1].
Ousterhout also came up with RAMCloud, which alas, never caught on. But you can find it in Github and about 4 guys got their PhD on it. He was an early (mid-late 2000s) of cheap PC h/w at scale yielding distributed K/V store with impressive timings.
