CPU Power Benchmark (CPUPowerBench)

CPUPowerBench is an automated benchmark to accurately generate a power model for single-board computers (Raspberry Pi, Asus TinkerBoard, BeagleBone, etc.).

Step 1: CPU Benchmark

:package: Automatic installation

Run the installer file: sh installer.sh in cpu-benchmark folder.

:floppy_disk: Manual Installation

First install dev tools: gcc, cmake, make, python 3, pip: sudo apt install python3 python3-pip gcc make cmake

Then install python requirements for CPU Load Generator: pip install -r requirements.txt

Then compile CPU Cycles program: cmake . make

:bulb: Usage

Connect your single-board device to a PowerSpy2 power meter.

Then, just run the benchmark script: sh start-benchmark.sh.

At the end of the experiment, two CSV files will be generated (cpucycles.csv and cpuload.csv). Finally, get the power meter data by using PowerSpy software and downloading the saved monitored data from the meter's internal memory, and rename the file to powerspy.csv.

Step 2: Power model generation

:package: Installation

Install python requirements: pip install -r requirements.txt in model-generation folder.

:bulb: Usage

Copy the 2 CSV files generated in the benchmark (cpucycles.csv and cpuload.csv) to the model-generation folder. Also, download power data CSV file from PowerSpy2, and copy it under the name powerspy.csv.

Then, just run the model generation script: python runModelGeneration.py in model-generation folder.

If you use a different powermeter or have a different CSV file structure for the power file, you can run the script with the powercsv option: python runModelGeneration.py powercsv. The option expects the CSV file to have two columns: timestamp and power consumption.
