Taking The Cores Offline
I have Intel® Core™ i7-2670QM CPU @ 2.20GHz × 8 process which has 4 physical cores and 4 logical cores.
Most of the time i been on AskUbuntu, Watching videos, Basically no processor hungry stuff.
So I was thinking to take cores offline but i have few question, I know i can take the core offline
cat /sys/devices/system/cpu/cpu7/online
1
echo 0 > /sys/devices/system/cpu/cpu7/online
So my question is:
Is it safe to take core/cores offline ?
Is it possible that my app crash ?
Does taking the cores offline save power ( On battery ) ?
