How to measure:
- system info
- on Asus ZenBook 14
- Ubuntu 20.04.3
- disable factors that affect energy usage
- disable power saving options in BIOS
- charge to full capacity
- disconnect all plugs (USB, HDMI) except power connector
- set screen and keyboard to full brightness
- turn off bluetooth
- kill GUI (go to terminal mode using Ctrl+Alt+F2, then kill GUI)
- note several factors
- cpu frequency using
cpuinfo - running processes using
psaux - battery level and charging state using
upower -i /org/freedesktop/UPower/devices/battery_BAT0
- cpu frequency using
- start Jupyter Notebook with
numactl -C 1 jupyter notebookto fix it on one CPU core - benchmarks
- idle (energy only)
- blas/lapack
- kmeans
