      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.
