Professionally, I'm a Site Reliability Engineer at Google. In previous jobs I was primarily a C++ software engineer working with embedded Linux devices. In my spare time (hah!), I like to develop video games.

comment Artificially burden the CPU
I finally attached a meter to my system to see which method causes the CPU to draw more power (more power == more heat). The burn programs of course win. The surprise is ls / > /dev/null draws nearly the same power as the urandom method.

I'm accepting your answer as "there is no way".

comment Upstart event based on level
It turns out 'coretemp-too-hot' is just the opposite of what I want. My script is to assist with device burn in. It only turns on the CPU roasting program when the temperature gets above 60C. I could instead emit a signal 'cpu-hot-enough', but I don't like that either. I was hoping to get my temperature emitter to act like a udev event.

It's not obvious from my question, but I need this utility to do heat test on an embedded device. While it's being cooked the only input is a serial line to verify the device is still alive. Would f@h run on a machine with no internet access?

cpuburn is able to heat up the processor more quiekly as well as get it a few degrees hotter. dd 57° C vs burnP6 60° C.

This may keep the CPU busy, but will it really stress it? The various cpu stressing programs for windows seem to try a lot harder than just continually copying memory (maxed out SSE while driving the ALU and FPU).
