Description: a collection of programs to put heavy load on CPU
 CPUburn is a collection of programs to put heavy stress on CPU. These programs
 are designed to load CPUs as heavily as possible for the purposes of system
 testing.

 Warning: The goal has been to maximize heat production from the CPU, putting
 stress on the CPU itself, cooling system, motherboard. This may cause data loss
 (filesystem corruption) and possibly permanent damage to electronic components.
 Use at your own risk.
