Charles J Murray: The Supermen: The Story of Seymour Cray and the Technical Wizards Behind the Supercomputer.
Sun, Mar 08, 2020./noise/books | LinkKindle. Not to be confused with the "supermen" theories of another Charles Murray. I was always a bit curious about what Seymour Cray actually did. Suffice it to say that this book is at the popular, business-y end of things with insufficient technical detail. It needed a bit of an edit. For most of it the author tries to push the unconvincing line that Cray was somehow conservative in his designs when clearly he had a lot of insight into the risks he was and should be running. Cray's greatest hits are the CDC 6600 (a prototypical RISC design by the sounds of it) and the iconic Cray 1. I don't know what exactly he was expecting from gallium arsenide semiconductors; Intel et al seem to have gotten there with silicon.
Incidentally Dijkstra worked at Burroughs from mid-1973 so I guess their paths didn't overlap so much. Little is said in the book about programmability and nothing about Brooks's software crisis.
