Stress Injector

Python module, to inject memory and CPU stress

Insights:

CPU Stress:

• To achieve CPU stress, I have used multiprocess, looped for the # of logical cores, triggering an infinite loop on each core.
• The infinite loop will run for a given # of seconds provided by user.
• Mean-while the cpu_percent from psutil runs (dedicated thread) in an infinite loop with kill signal set to False calculating the current CPU utilization on each CPU core.
• Once the given # of seconds have passed, the kill_signal is set to True and some painful steps to gracefully stop the multiprocess and multi-thread.

Memory Stress:

• In this script, I have used numpy.random.bytes which are sampled from uniform distribution.
• Generating these random bytes induces a stress on the machine's memory usage.
• I have then used getrusage (get resource usage) for SELF to get the memory consumed only by the current script.
• The size_converter converts the bytes from resource usage to a human understandable format.
