I use "fastest to complete == least power usage" as a rule of thumb because of "race to sleep". I suppose that might be thrown off by power usage characteristics varying based on number of cores working? How does one even begin to write code that prioritizes power-efficiency over performance?
- to3m 10y agoFor short runs, any fixed-cost warmup/cooldown periods might dominate - a latency/throughput tradeoff kind of affair. (I am just shooting my mouth off and have no idea whether that's the case here.) As for how to do it, I'm not sure... but if I were a valued customer of various CPU suppliers, and were famous for the depth of my pockets, I'm sure I'd be able to find somebody to explain it to me ;)
