I visited Tennessee once, walked by a bar and saw a sign saying «Jack lives here». Fun story.

Also, well deserved. I still recall the one talk by Jack Dongarra I ever saw. He threw out there that the iPad 2 had (at the time) the highest performance-per-watt CPU in the world. I’ve waited for the «apple M1 moment» since then - and now, suddenly… fantastic talk covering the whole HPC topic!
