StressLinux (Score 1)

I have been using this for a while and it works great.

From the StressLinux website:

stresslinux is a minimal linux distribution running from a bootable cdrom or via PXE.

stresslinux makes use of some utilities available on the net like: stress, cpuburn, hddtemp, lm_sensors ...

stresslinux is dedicated to users who want to test their system(s) entirely on high load and monitoring the health.
