I worked there years ago, so here's a bit of trivia. The Cray Supercomputers you see in Seattle is an acquirer of Cray Research. The original Cray was bought by SGI in the late 90s and sold to a Seattle supercomputer startup named Tera in the 2000s with some help from the US government-- unhappy about how SGI ran Cray. The company still kept a surprising percentage of its early engineers, despite passing through several owners and changing HQ locations.
