I would like to benchmark some object methods. I can create a timer with
"boost::mpi::timer" for get time on all cluster nodes.

Is there any solution to get the time profile on seperated function
or methods?
I need only the information whitch functions are the "slowest"

Get a real tool - a profiler. They are OS-specific. Linux has gprof,
VTune. Windows has LTProf, AQtime, VTune, GlowCode, etc. Mac... I
don't know what
Mac's got. In most of them you can profile your functions
selectively. Don't reinvent the wheel, no matter how much appealing

Damn, I'm developing under OS X and than I port the code to a gui-less
Gentoo Linux cluster. Is there any kind of solution to check the
function with boost-only precompiler options?

I don't know, sorry. I know, however, that Boost has online forums
where you can probably ask for more assistance (wink-wink).
