cpuburn?

i just completed an update/upgrade.
a new package has appeared that i did not remember installing called cpuburn.

the discription fo rhtis is as follows:
	CPUburn is a collection of programs to put heavy stress on CPU.
	These programs are designed to load x86 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.

this worries me.
how do i determine what created this dependency?
is it safe to remove?
is it safe to run?
