100% CPU usage), heat (temperatures), clock speed/CPU frequency, voltages, etc. Generally, put target CPU under exaggerated stress levels like extremes of workload (e.g. To accordingly optimize CPU noise level.To accordingly optimize CPU cooling system.To confirm intended specifications are being met.To test CPU stability beyond standard usage and its limits.Usually, people, especially CPU manufacturers need to carry out a stress test CPU for the following reasons: Why Need to Do CPU Stress Test?ĬPU reliability engineers often test CPUs under expected stress or accelerated stress for determining the operating life of CPUs. Therefore, the CPU stress test is to torture a CPU and make its main parameters to reach the breaking points. It involves tests beyond normal operational capacity, usually to a breaking point, to observe the results. A stress test is used to determine the stability of a system, critical infrastructure or entity (hardware). On This Page :Īccording to Wikipedia, a stress test is a kind of thorough or deliberately intense test it is also known as a torture test.

To stress test the CPU, install the stress or stress-ng package - it should be in the repositories for most Linux distributions.This essay will tell you what’s a CPU stress test, the benefits of the test, how to operate guide as well as the best CPU stress test tools. If it's not, open ~/.bashrc (or ~/.zshrc, etc., depending on what you're using) with a text editor and add this at the bottom of the file: export PATH=$PATH:$HOME/.local/bin, open a new terminal and you'll be able to run s-tui without typing its full path. The s-tui executable is installed in ~/.local/bin so make sure this directory is in your PATH. Python3 -m pip install -upgrade -user s-tui The s-tui installation instructions mention the option of installing s-tui using pip, but since the instructions mention using "pip" directly, which can point to either Python2 or Python3 depending on the used Linux distribution, I thought I'd mention that you must install it using Python3. Though as expected, it's not yet updated to the latest version in most cases (and in Ubuntu it won't be until Ubuntu 20.04). S-tui is available in the official repositories for some Linux distributions, including Debian Buster and newer, Ubuntu 19.04 and newer, Arch Linux / Manjaro and openSUSE. Another menu showing the maximum / minimum / average for all sensors is planned for a future release. It's also worth noting that some features were removed in this release in order to make s-tui more modular: reading the maximum frequency with root for all cores, and displaying the maximum recorded temperature. This should make it a lot easier to add a new source, by simply implementing all the class methods. There have also been some important under the hood changes, with everything being made a lot more modular. Also, selected graphs are now stored for future uses. There are now two sections, called Graphs and Summaries, from where you can enable or disable any graph or sidebar information. With s-tui 1.0.0, you can toggle both the side menu items and graphs on off. In previous versions you could only toggle the graphs on or off.

With this first stable release, there are now multiple graphs for each source - the CPU temperature, frequency and usage graphs are now per core, etc. In case you want to use it in a TTY and it crashes on start, run it with the -no-mouse option to disable mouse input support, and get around this issue.Īnother cool s-tui feature is the ability to run a shell script when a certain threshold is exceeded.įor the 1.0.0 release, s-tui went through some important under the hood and user interface changes. If you prefer to use the mouse instead of keyboard, you can do that as s-tui has mouse support. For the sidebar though, you can use h j k l to navigate it without resizing the terminal window. The TUI (terminal user interface) application has a responsive interface, similar to bandwhich, so the information it shows depends on the size of the terminal window.
