I never could figure out (2000's-era) Cray. Their office was in my neighborhood and a friend-of-a-friend worked there and it sounded like interesting work, so I checked out their jobs page. Almost all of the jobs were sales, and their most junior engineering position required something like 10-15 years HPC experience. I've seen successful niche technical industries (Fluke comes to mind), and Cray didn't even look like a niche industry. It looked like a dying one.
