I'd never heard of him. He's done a lot of interesting stuff, mostly in high performance computing. From his personal page:
"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?

- boltzmann_brain 7y agoI only heard of him recently and just went through his presentation about Unums, available on his page. Great stuff, highly recommended. http://www.johngustafson.net/presentations/Unums2.0.pdf http://www.johngustafson.net/presentations/Unums2.0.pdf

- carlsborg 7y agoAmong other things he is famous for what came to be called Gustafson’s law: http://www.johngustafson.net/pubs/pub13/amdahl.htm http://www.johngustafson.net/pubs/pub13/amdahl.htm “Speedup should be measured by scaling the problem to the number of processors, not fixing problem size”
