This is the stress-ng upstream project git repository. stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces.
stress-ng command line added to NAS $PATH
stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces. Stress-ng features:
Over 260 stress tests
85+ CPU specific stress tests that exercise floating point, integer, bit manipulation and control flow
over 20 virtual memory stress tests
portable: builds on Linux, Solaris, *BSD, Minix, Android, MacOS X, GNU/Hurd, Haiku, Windows Subsystem for Linux and SunOs/Dilos with gcc, clang, tcc and pcc.
tested on x86-64, i386, s390x, ppc64el, armhf, arm64, sparc64, risc-v, m68k, mips64
stress-ng was originally intended to make a machine work hard and trip hardware issues such as thermal overruns as well as operating system bugs that only occur when a system is being thrashed hard. Use stress-ng with caution as some of the tests can make a system run hot on poorly designed hardware and also can cause excessive system thrashing which may be difficult to stop.
stress-ng can also measure test throughput rates; this can be useful to observe performance changes across different operating system releases or types of hardware. However, it has never been intended to be used as a precise benchmark test suite, so do NOT use it in this manner.
Running stress-ng with root privileges will adjust out of memory settings on Linux systems to make the stressors unkillable in low memory situations, so use this judiciously. With the appropriate privilege, stress-ng can allow the ionice class and ionice levels to be adjusted, again, this should be used with care.
