Podcast: John McCalpin Surveys HPC System Memory Bandwidth

"In the long run, if you need orders of magnitude more bandwidth than is currently available there's a set of technologies that are sometimes referred to as processor in memory - I call it processor at memory - technologies that involves cheaper processors distributed out to adjacent to the memory chips. Processors are cheaper, simpler, lower power. That could allow a significant reduction in cost to build the systems, which allows you to build them a lot bigger and therefore deliver significantly higher memory bandwidth. That's a very revolutionary change."
