Nice article.

There is a nice gui tool for the same purpose,
http://developer.amd.com/tools-and-sdks/opencl-zone/codexl/
I find it easier to use then perf since it lists the useful 
statistics as a table.
Also very useful is valgrind --tool=callgrind
and the gui for it kcachegrind.
http://kcachegrind.sourceforge.net/

I used it to optimize the newCTFE code with great success.
Also I would recommend to compile the executable you are 
profiling with -g -gc, as you will be able to see which lines of 
code asm instructions correspond to.
