"Gustafson has recently finished writing a book, The End of Error: Unum Computing, that presents a new approach to computer arithmetic: the unum. The universal number, or unum format, encompasses all IEEE floating-point formats as well as fixed-point and exact integer arithmetic. This approach obtains more accurate answers than floating-point arithmetic yet uses fewer bits in many cases, saving memory, bandwidth, energy, and power."
Has anybody read it?

“Speedup should be measured by scaling the problem to the number of processors, not fixing problem size”
I was lucky enough to tour the Chippewa Falls facility early on - serial number 5 of the Cray-1 was undergoing final tests before delivery.
We were lucky enough to see Seymour in his office. He pointed to a pumpkin on his desk, and declared that it was the Cray-3. His daughter had grown it, and since she knew he was already working on a Cray-2, she decided this would be the Cray-3.
If you read any biographies of US physicists of the time, it seems they either all sailed, or had a close scientist friend that owned a boat.
