      Stress test a computer system in various selectable ways, by exercising
      various physical subsystems of a computer as well as the various
      operating system kernel interfaces. Stress-ng features:
      - over 60 different stress tests
      - over 50 CPU specific stress tests that exercise floating point,
        integer, bit manipulation and control flow
      - over 20 virtual memory stress tests
      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.
