Stress test a system in various selectable ways, exercising both various
physical subsystems and various operating system kernel interfaces:
2016-07-14 16:06:54 +00:00
- 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.
