Last week I attended the Arm Research Summit, and on Tuesday there was a panel session on using Arm hardware for performance, an effort known as GoingArm. You can watch the whole panel on youtube, from 2:12 onward (~1h30). All videos are available on the website.
It was interesting to hear the opinions of people in the front lines or ARM HPC, as much as the types of questions that came, which made me believe even more strongly that now is the time to re-think about general computing in general. For a long time we have been coasting on the fact that cranking up the power and squeezing down the components were making the lives of programmers easier. Scaling up to multiple cores was probably the only big change most people had to deal with, and even so, not many people can actually take real advantages of it.
