We can scale horizontally (more machines) as well as vertically (faster machines). If reasoning about more machines is easier than imagining faster machines (implicitly here: ones with more cores), then going the other route could be better
- sz4kerto 12y agoThe problem is exactly that we can't scale vertically. Look at single threaded performance charts -- they're already far below Moore's Law. STP/watt is increasing quickyl, but peak performance per core isn't really. (It is, but the second derivative of performance vs time is already negative.)
