        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 210 stress tests
          * over 50 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,
            Debian Hurd, Haiku, Windows Subsystem for Linux and SunOs/Dilos with
            gcc, clang, tcc and pcc.
  
        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.
