Best way to peg CPU usage?

I am trying to run down a signal 11 problem. I suspect it may have to do with CPU cooling. Can anyone suggest a way to easily nail all the cores on the CPU with some process that would be sensitive to a hardware fault?

I have tried making world but I need a test that can run longer.
 
Build OpenOffice :D
Or if you think that is short, build all localized OpenOffice packages :D

And remember to turn off distcc and/or ccache if you're using one of them
 
<rimshot> I walked in to that one!

Looks like I may have fixed the underlying problem, knock on wood... I think it was poor CPU cooler mounting.
 
I've done it before, because my laptop was overheating with FreeBSD. Due to missing voltage modulation on ATI VGA, I could drive the CPU that was sitting under the same cooler to over 100°C which forced an automatic power-off.

A simple way is to run openssl speed -multi <number-of-CPUs-times-2> in a loop. Compiling in a loop is also fine, but you need to saturate all the available cores.
