CPU Load Generator

This package allows to generate a fixed CPU load for a finite time period. The script takes in input the desired CPU load, the duration of the experiment and the CPU core or all cores on which the load has to be generated.

Python versions This master branch refers to Python versions 3.x

Dependencies Installment of psutil is required (it is already set as dependency in the setup.py)

Install psutil:

pip install psutil

Other dependencies for unit tests and linters:

pip install mock pytest flake8 tox

Usage To generate 20% of load on core 0 for 20 seconds run:

python -m cpu_load_generator -l 0.2 -d 20 -c 0

To generate 50% of load on all logical cores for 20 seconds run:

python -m cpu_load_generator -l 0.5 -d 20 -c -1

There is an option to run CPU load based on profile file. An exemplary profile is under load_profiles/default_profile.json. In order to run generator based on a profile issue the following command:

python -m cpu_load_generator -p <path_to_profile_json>

To use the package features from python code:

Install the package from PyPi by issuing the following command:

python -m pip instal cpu-load-generator

To use its features from your code:

from cpu_load_generator import load_single_core, load_all_cores, from_profile

load_single_core(core_num=0, duration_s=20, target_load=0.4)  # generate load on single core (0)
load_all_cores(duration_s=30, target_load=0.2)  # generates load on all cores
from_profile(path_to_profile_json=r"c:\profiles\profile1.json")
