        Stress test a system in various selectable ways, exercising both various
        physical subsystems and various operating system kernel interfaces:
        - over 130 different stress tests
        - over 70 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.
