stress-ng

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:

  * nearly 120 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. 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.

To build, the following libraries are required:
	libattr1-dev, libkeyutils-dev

To build on BSD systems, one requires GNU make
