I've got a question about the energy consumption of my mic code. Here are the specs of my system:
cpu code running on: i7-4700 mq 4core (haswell) on my laptop, tdp=47w, windows os
mic code running on: 5110p 60core (knights corner) on my server with an xeon x5650 6core cpu, tdp=225w, gnu/linux os
I found that with 8 threads my cpu usage is 100% and the power always hits its tdp, but my mic with 240 threads only spends ~150w, much lower than its tdp. since my mic code does not contain vectorized part, so can i conclude that the vpus on mic are not used, hence the power is much lower than the tdp? Thanks for clarifications!
