The record

Purpose: stress-ng stress tests computer systems by exercising physical subsystems and operating system kernel interfaces.
Stress tests: The project lists 390+ stress tests, including 100+ CPU, 60+ virtual memory, 80+ filesystem, and 50+ memory or CPU cache tests.
CPU coverage: CPU stress tests exercise floating point, integer, bit manipulation, and control flow operations.
Platforms: The README lists Linux, Solaris, BSD variants, Minix, Android, MacOS X, Serenity OS, GNU/Hurd, Haiku, WSL, Cygwin, and SunOS/Dilos among supported or tested systems.
Architectures: The README lists test coverage across architectures including ARM, x86-64, RISC-V, MIPS, Power, SPARC, and s390x.
Use cases: The project says it was originally intended to expose hardware issues such as thermal overruns and operating system bugs that occur under heavy load.
Throughput metrics: stress-ng can measure test throughput to observe performance changes across operating system releases or hardware types, but the project says it is not a precise benchmark suite.
Usage caution: Some tests can make poorly designed hardware run hot and cause excessive system thrashing that may be difficult to stop.
Privileges: When run as root on Linux, stress-ng adjusts out-of-memory settings so stressors are unkillable in low-memory situations; the README advises judicious use.
Packaging: The README documents running the latest snapshot in a Docker container and installing recent Ubuntu versions from the project’s PPA.
Build dependencies: The build detects optional library dependencies and can disable functionality when support libraries are missing.
License: The repository identifies its license as GPL-2.0.
Support and contributions: The README invites patches by email or merge requests through the stress-ng GitHub repository.
