@HPCpodcast-110: John Gustafson on AI, HPC, Making Every Bit Count – In Depth

Can AI and high-performance computing get better answers with fewer bits? HPC pioneer John Gustafson, author of Every Bit Counts, joins Doug Black and Shahin Khan to challenge the default reliance on 64-bit floating point, and explain why numerical precision belongs at the center of the debate over computing performance, memory bandwidth and energy use.

@HPCpodcast-37: John Gustafson on Feynman, Gustafson’s Law, Posit Format

How did Richard Feynman end up playing the bongo drums? How did a new take on Amdahl’s Law helped propel massively parallel computing and become Gustafson’s Law? And what’s wrong with IEEE 754 number format that the new Posit format fixes? We go to the source as we welcome special guest John Gustafson in another very lively conversation.
