Performance per Watt is indeed the killer in HPC. I am not sure I agree ARM have no future in HPC. IMO, the window of opportunity has never been larger for them. It'll take time, yes, but I think it will happen.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
